All of Ichika Orimura's relationships.

Morioka Creators

A group of people responsible for his, Chifuyu, and Madoka's creation. Ichika was unaware of their existence nor his true origins when Tabane revealed the truth, which greatly shocked him. Although they viewed him as a success at first, they later decided to destroy him since he was more than what they expected, forcing Chifuyu to flee with him.

Family

Chifuyu Orimura

Young Chifuyu and Ichika.

Chifuyu is Ichika's older sister as well as his homeroom teacher of Class One and 1st year dorm supervisor. Originally a legendary pilot of the 1st generation IS, She took care of him after their parents had abandoned them. Despite the harsh treatment he regularly gets from her, Ichika loves her deeply. She was also the one who transferred him to the IS Academy to ensure that he would be safe from the other governments.

Although he does not remember much of the events that transpired during his kidnapping, it was his sister who came to save him when he was young. Though grateful, he still feels deep regret over the incident as it cost Chifuyu's title, showing how much respect he has for his sister’s pride and reputation. As seen or stated, Ichika is willing to give his life to protect her at all costs.

They both share a common desire to protect one another, acknowledging that they are the only family the other has. At home, the relationship between the two is way more casual, as Ichika does all the housework while Chifuyu is working and he would give her massages to help her relax. While Ichika thinks this is normal because they're siblings, the other girls think they look more like a married couple than brother and sister, something that they are envious of. They are even worried that Ichika might have a sister complex toward Chifuyu and likewise. Despite rarely showing it, Chifuyu greatly enjoys that Ichika treats her much better than other girls (including those who love him), much to their annoyance and jealousy. However, Ichika is sometimes bothered by her unwillingness to share information with him, especially about their family. He was shocked when his and Chifuyu's origin was revealed by Tabane.

Madoka Orimura

Madoka is Ichika's younger twin sister. She holds a grudge towards her older sister, Chifuyu, because she feels that she abandoned her, which leads her to join Phantom Task as an IS pilot of Silent Zephyrs. Both have clashed against each other numerous times in battle and when she reveals her true identity to Ichika at the end of Volume 6, he begins to question the forbidden topic of family. It can be assumed that she's at least aware that Ichika doesn't know who she is given the fact that she introduces herself to him. It is later revealed that Madoka despises him because Chifuyu gave priority to him instead of her and abandoned her. She came close to killing him in Kyoto with her new IS Kurokishi, but was stopped when Shirokishi took control of his body. After this, Ichika comes to accept that Madoka is his enemy and resolves to fight her when the time comes.

Childhood Friends (Normal) and Family-related people

Dan Gotanda

Dan has been Ichika's good friend since middle school. He is often mentioned by Ichika that he wants to switch places with him to enjoy "paradise" in the IS Academy. They often play video games together in the Gotandas' home when Ichika comes to visit. Dan is also well aware of how dense Ichika is towards the feelings of girls around him that they have for him, including his sister Ran.

Ran Gotanda

Dan's younger sister. Like in Dan's case, Ichika is on good terms with Ran as he has known her for a long time. Due to being dense, he is unaware that she has a crush on him, which causes Ran to be annoyed by him.

Kazuma Mitarai

Another friend from middle school. He appears in Volume 5. Like with Gotanda siblings, they are on good terms with each other.

Tabane Shinonono

Houki's sister and childhood friend of Ichika's older sister Chifuyu. Tabane calls him affectionately as Ikkun (Short for Ichika-kun), and he has a mutual respect for her, though he too is somewhat overwhelmed by her explosive energy. Most notably, Ichika never scolded or lashed out at her out of annoyance like Houki and Chifuyu. However, he has become increasingly cautious around her due to her involvement with Phantom Task. It is also Tabane who reveals to Ichika the secret of his and Chifuyu's birth and the truth about their parents which they didn't have, and then casually calls him a monster in conclusion, breaking him in the process.

IS Academy

Being the only male student at the academy, Ichika is usually the center of attention there. Almost all of the students are interested in him and become excited at any chance to be around him. They can sometimes be very demanding of him, wanting him to treat them like he usually treats the personal IS pilots, and get upset when he refuses to do so. Most of the girls in his year are completely comfortable around him, not having any problems being in situations where he could see them in their underwear or touch their bodies. If anything, they even want him to. The older students are even more bolder, coming off as seductive and flirty when given the chance.

Many of the girls seem to prefer it if Ichika treats them as his own harem, calling the academy his harem kingdom. They get upset whenever they think he's giving one girl favorable treatment or looks like he's going out one. Some have even outright said Ichika belongs to all of them and has a duty to please them in whatever way he can. While they don't seem to share the same kind of feelings as the main heroines, the majority of them do like him. Although there are some who aren't interested in him, either because they like someone else or they don't swing that way, the prime example being Daryl Casey and Forte Sapphire who are dating each other, along with being part of Phantom Task.

Main Heroines

The closest friends Ichika has made at the Academy would be with all the personal IS pilots of his year as well as Tatenashi. Although Ichika got off on the wrong foot with most of them (which was never his fault, to begin with), his steadfast and noble personality, along with his kindness, won him their hearts, something that everyone but him noticed. After that, they would try to spend as much time with him as they could, usually under the excuse of helping him get better at piloting the IS. However, Ichika failed to understand this and ended up spending time with them as a group (which made them closer to one another).

While the girls all love him and have become very close friends with each other, they're always quick to get jealous and angry whenever he seems to be giving any one of them (or another girl) more attention than the rest of them, which they react with violence, ironically making them more of a danger to his life than his actual enemies. This usually results in them demanding him to 'repay' them in some way. Despite this, they do value his life, which was clearly shown after Ichika was killed by the Excalibur protecting Cecilia; they were all utterly devastated and almost lost the will to continue. After he was revived, they were all extremely relieved and overjoyed to see him alive again.

Houki Shinonono

His 1st childhood friend and a classmate in Class One. They used to train in kendo when they were young. About six years before the current storyline, Ichika agreed to become her boyfriend if she won the national kendo tournament of their grade. He told her that he was glad to be her roommate, as he was worried about sharing the same room with a total stranger. Ichika, due to his nature, sees Houki as an extremely strong childhood friend of his. He is willing to do things for her that he probably might not do for others. However, before the events of the Shinonono festival (which takes place sometime after the events of Season 1, Episode 12), they had practically dated and nearly kissed, implying that he may have some sort of emotions regarding Houki. Unfortunately, Ichika's kiss is comically obstructed by Cecilia, Rin, Charlotte, and Laura, causing him to run away while carrying her with a comical worried face showing "he is going to die".

Ichika and Houki almost kiss during a photo shoot (if they were alone and that's what happens in Houki's mind).

In addition, during the episode of "Lovely Style," he is well aware of the attractiveness of the heroines. However, during Houki's turn, there is a moment where they feel a "spark" between them, but they are interrupted by Yamada-sensei. Also in the light novel, his inner monologue during their photoshoot after their interview with Nagisako indicates that he realizes Houki's beauty when she's all dressed up, to the point where he said it was intoxicating. Another example can be seen in Volume 8, while Ichika was annoyed by the other girls' delusions of him, but he seems more jealous of how much better Houki treated the fake Ichika than she ever treated the real him.

Houki loves Ichika to the point where she manages to muster up enough courage to confess to him at the Shinonono festival. However, right when the words "I love you" were said, fireworks exploded, rendering her words inaudible. Her emotional state is also somewhat dependent on her relationship with Ichika, as shown when Akatsubaki's One-Off Ability is activated after excessively thinking about him. Additionally, when he was injured while saving her life by taking a blast meant for her, she was so depressed that she nearly stopped piloting her IS altogether.

Cecilia Alcott

Ichika helping Cecilia cook by overlaying his hand over hers

His classmate in Class One and the IS Representative Candidate of England. They originally started in a bad way. She challenges him to a representative duel as she believes it to be biased. After giving her a hard time in the duel, she soon starts to see him as a true man and falls in love with him, calling him affectionately "Ichika-san," much to his confusion and Houki's displeasure.

Ichika hugs Cecilia on her birthday.

Ichika sees Cecilia as a fellow student and a good friend on most occasions. Of course, the comical and awkward scenes that have involved her before may imply something beyond the boundaries of friendship. Of course, this is completely unconfirmed. They are on relatively good terms, which most likely means that Ichika does not care about the prior incident when they dueled for the position of "Class Representative". Ichika even gave her a massage to make up for not being able to feed her, something she found blissful. Over time, Ichika has come to see Cecilia as a very beautiful young woman and a dear friend.

By volume 11, there are hints that Ichika has started seeing Cecilia in a romantic light, which makes the other girls extremely jealous had how close the two have become. He shows strong concern for Cecilia and doesn't hesitate to go with her back to England after Chelsea's strange actions. While around her, he shows concern yet sometimes a little teasing. During Cecilia's birthday party, Ichika acts more intimate and a little bit more mischievous towards her. At her request for her birthday present, Ichika embraces Cecilia.

In Volume 12, their relationship was shown to be a bit more romantic as Ichika showed no hesitation or embarrassment in regards to feeding her a parfait or complimenting her on her "curves"

Cecilia is in love with Ichika to the point of fantasizing about him. While it has happened with all the main heroines of the series, it is undeniable that Cecilia is no exception. Her love for him is a little shallow, but it is love nonetheless, and she puts in as much effort as the rest of the girls.

Lingyin Huang

Lingyin trying to kiss Ichika

His 2nd childhood friend, who is the IS Representative Candidate of China and a student from Class Two. She has been in love with Ichika since he protected her against her school bullies. Ichika sees Rin as a really good childhood friend, and this is shown when she is first introduced. He addresses Rin without any other proper honorifics, which shows his good relationship with her. When they are eating together in the cafeteria during this time, they have already engaged in a very deep and long-winded conversation.

Rin has loved Ichika for quite some time already, and this is shown when she mentions the promise they made to each other when they were much younger. Notably, she and Cecilia Alcott share a similar trait of a yandere girlfriend. This is first shown when Charlotte and Ichika go to the mall by themselves.

While Rin meant for them to become a couple, Ichika had misinterpreted the promise (with his usual blockheadedness) as getting free sweet and sour pork every day on Rin's behalf. In fairness to Ichika though, the promise was phrased as "If I become a better cook, would you eat my sweet and sour pork every day?"

However, he does seem to have some feelings for her, as in Side Story 3, Lingyin manages to convince Ichika to dry her bare breasts with a towel, while for all other girls, he had instantly refused to even dry their backsides.

Charlotte Dunois

The IS Representative Candidate of France. She was sent as a spy by her father to figure out how Ichika could pilot an IS. After her transfer, she becomes Ichika's roommate where he later discovers her true gender. Upon learning that Charlotte's father and his corporation used her to spy on him, Ichika decides to help and protect her, being reminded of his own history with his parents.

Charlotte hugs Ichika.

When they first met, Ichika was under the impression that all the other students were under, which was that Charlotte was a male student known as Charles. During that time frame, Ichika was on extremely close terms with Charles/Charlotte due to his lack of male contact. On the very first day, they had already established a very close friendship.

After the discovery of Charlotte's/Charles' true gender, Ichika's opinion and friendship towards her are completely unwavering. Although some events happen between them that are undeniably awkward, they have maintained an extremely good relationship. Ichika even gives Charlotte a nickname for just the two of them (Charl).

The two are extremely good partners during IS battles for some reason, as shown when they coordinate their attacks extremely well during the match with Laura and Houki. Additionally, Charlotte is able to transfer energy over to Ichika's IS, which is something that is initially fairly (if not highly) difficult to do. This already proves how close they are.

While Ichika views Charlotte as a very good friend and a powerful companion, Charlotte has undeniably fallen in love with the dense Ichika. Her very mannerisms are extremely flustered when around him, and this merely proves that she has very intense feelings for him. While Charlotte is no doubt the gentlest and most forgiving of the harem, she has also shown herself to be extremely scary. This is shown when she gets mad at Ichika for whatever reason, and Ichika's inner monologue has described her smile as scarier and more demonic than the kind and angelic one it usually is.

Nevertheless, their bond was close enough for Charlotte to sense that Ichika was in danger right at the moment when Tabane mentally broke him after calling him a "monster".

Laura Bodewig

The IS Representative Candidate of Germany. Laura came to the IS Academy to punish Ichika, and he thought that she blames him for his sister withdrawing from the IS International Fighting Tournament, Mondo Grosso, in order to save him when he was kidnapped in the past and denying Chifuyu the right to win, the fact that Ichika was kidnapped was something that Laura was not aware of. But actually, Laura hated Ichika because she believed that he made Chifuyu look with a weak expression.

Laura kisses Ichika.

Ichika first had a fairly negative impression of Laura, as she had practically attempted to kill Rin and Cecila in what was supposed to be a mock battle. However, after discovering that she looked up to Chifuyu greatly, and also had similar issues to any other normal person, he treated her with kindness and friendship regardless. He trusts her like he would trust any of the other girls at school anyway. Afterwards, he starts considering her a woman, even calling her "cute" when Chifuyu questions him about his feelings for her.

Laura's first impression of Ichika was far more negative than the latter's. Believing Ichika to be a hindrance to Chifuyu's image in her eyes, Laura did not like him at all. However, after Ichika saved her from her mutated IS, they seemed to have shared a brief moment of conversation before she had fallen unconscious. When Laura saw that Ichika's characteristics were also extremely similar to that of Chifuyu, it's safe to assume that she had decided to fall in love with him right then and there. As time progressed, her feelings for him deepened to the point she started acting like a typical girl in love, even becoming very shy from happiness when Ichika held her or complimented her looks.

In volume 9, it is implied that he has started to see her as a woman, even inviting her out for drinks without a good reason. Before getting killed by the Excalibur, Ichika had trusted Laura to handle the rest. While Laura resents him for it (as it robbed her of the chance to mourn his death), it allows her to stay focused when both Houki and Lingyin have already fallen into shell shock, thus she is still devastated and wants revenge against the Excalibur for killing Ichika.

Tatenashi Sarashiki

Tatenashi with Ichika

“	Welcome back. Do you want dinner, a bath, or... do, you, want, me?	„
	― Tatenashi Sarashiki to Ichika Orimura[src][src]

Tatenashi is teasing Ichika with her body

The Student Council President of the IS Academy, the IS Representative Cadet of Russia, and the head of the Sarashiki family. On Chifuyu's order, Tatenashi becomes Ichika's bodyguard as well as his third roommate, but she often creates mischief for him. At first, he usually doesn't like her company because she always ends up teasing him. But when it comes to important matters (such as Phantom Task or family), they talk to each other more seriously, although she will usually break the atmosphere by teasing him again or playing a prank. However, when Ichika talks about her, she does it with respect and she praises it. Another part of the reason why Ichika is uncomfortable around Tatenashi is because she sometimes gets too physically close to him with her very voluptuous, mature body (Ichika often states that Tatenashi's figure is good, and not just good, but really outstanding). She also teases him with it by dressing scantily in front of him and demanding that he massage her whole body, which Ichika considers 'dangerous' for a young man like him. Ichika thinks that her body feels great to touch, and it feels good to massage it. Also, when Tatenashi asks him to massage her butt, Ichika does not oppose it and really likes the feeling of it, having a nosebleed while doing so. When Autumn attacks Ichika, Tatenashi appears to protect him, but Autumn's mechanical IS arm pierces Tatenashi's body (it is not known that it is actually one of her clones). As soon as Ichika sees this, he screams in pain and is very angry. But he calms down when he finds out he's okay. When Autumn tries to escape by throwing IS into the air, Tatenashi prostheses her by creating a force field. However, Tatenashi prosthetically added him using her body, but it didn't seem to bother her that her breasts were on Ichika's face. Tatenashi also asks him what he thinks of her breasts. Although Ichika hesitates a little at first after looking at Tatenashi, she says shyly "Huh, no, well...it-it's really soft...I guess..." After that, Tatenashi makes a little fun of him.

Throughout Volume 6, it is shown that she is becoming more mindful of Ichika, even thinking of him on random occasions. While she doesn't mind teasing him or putting him in situations he doesn't want to be, she has complete trust in him. Ichika is also aware of Tatenashi's beauty and the pleasure when her body touches his body. When Tatenashi wants to tickle Ichika, he considers even this contact is dangerous for a man like him because of her “voluptuous chest and tender thighs that were touching me while tickling...” When Ichika starts to massage Cecilia, he compares her with Tatenashi 2 times: first is when Cecilia wants to undress her lower part, and second is when Ichika is massaging her butt, he thinks: He wouldn't lose, not even to Tatenashi-san's and trying to stop thinking to it. However, when Ichika is massaging Tatenashi's butt, he is overwhelmed at how soft her butt is, and it is chosen with a nosebleed. Even when he's just thinking about touching her butt, Ichika can feel how much blood is about to come out of his nose if he doesn't stop thinking about it.

Tatenashi getting in on the fun

“	"Please, Ichika. I’m being serious. Tatenashi?"	„
	― Tatenashi Sarashiki and Ichika Orimura[src]

In the episode of "Lovely Style", Ichika sees Tatenashi wearing a Neko Cat outfit. He's a little shy after looking at a little more of her feminine parts, unlike the other girls. When Tatenashi tells Ichika that she is serious, it seems to become more affordable and that a moment has arisen special between them, but it is interrupted by Lingyin. While she doesn't mind teasing him or putting him in a situation he doesn't want to be in, she has complete trust in him.

“	"Both of them seem to have quite the good relationship."	„
	― Kanzashi Sarashiki[src]

In Volume 7, Tatenashi even asked Ichika to be partners with her little sister Kanzashi when she was having trouble getting along with her (when Kanzashi goes to Ichika's room, he sees it with his big sister Tatenashi, although he sees them for a short time, she affirms "Both of them seem to have quite the good relationship."). This ends up with the two sisters finally making up with each other at the end of Volume 7. Afterwards, she questions herself on why she asked him in the first place and admits to herself that she wanted to flirt with him, blushing as a result.

“Ichika...”

Also, their relationship and feelings for each other are deeper in Volume 8 when Tatenashi is shot in the back by an American soldier, she mutters his name before falling unconscious. In the research room, Ichika, who had his IS in open mode, hears his name in his mind and goes to save Tatenashi (also, Ichika had no IS or other communication devices with him, the Academy's communications did not work and no one else told him he just heard his name “Ichika” and it occurred or better said felt that Tatenashi is in danger, it means that a special bond was formed between them).

Ichika heard his name in his mind from Tatenashi or better said felt that Tatenashi was in danger

After Ichika saves Tatenashi from being kidnapped by the American special forces, she reveals her true name, (更識 刀奈 Katana Sarashiki), to him while they are in the Academy's infirmary, which has a special significance in the Sarashiki family, indicating that a certain level of affection has grown between them (at least from her side; also Ichika is happy to know a little bit more about her). She also exhibits a jealous reaction towards Ichika after mentioning the lewd exploits of the fake Ichika and the other girls. This suggests that she does feel the same way the main harem does since she asks him to do similar things to her as well. Even the manner, in which she asks him to do it, is also different from the way she used to do it before; in a shy, nervous tone compared to her previous playful, straightforward one. She also has him call her by her real name when they're alone.

Tatenashi and Ichika to the Academy's infirmary

In Volume 9, their respective positions in the relationship become reversed. Ichika is no longer uncomfortable about being close or intimate with her and even takes the initiative to see her, even without a good reason. While Tatenashi herself becomes shy about Ichika and is the one who is constantly confused about their relationship, this in turn causes them to behave more like a real couple, which more than a few people point out. However, she is initially not entirely in favor of this development, noting the value in her duty and reminding herself that falling in love is the only thing she can't do, only to fail to deny it when questioned about it by Chifuyu. She changes her mind after their 'evening' together, by realizing that when she is by his side, she isn't Tatenashi, head of the Sarashiki family or student council president, she is only Katana. She's even willing to consider marrying him and using her authority as the IS representative of Russia to smuggle Ichika to Russia should it be necessary.

His feelings for her are on a much deeper level compared to the other girls. He purposefully makes Tatenashi lunch made of her favorite foods and subsequently insists on feeding it to her. He is even perfectly calm and decisive about touching her body and complimenting her on it. He even compliments her on features that the other girls don't have. He can always recognize when she is facing difficulties or is trying to deflect him. He is very interested in talking about Russia after imagining Tatenashi wearing a long fur coat and hat. He even asks her if he can go with her one day to Russia, only the two of them. After the mission, Tatenashi says that they missed the reservation at the restaurant and suggests returning to the Academy, but Ichika refuses and suggests another one. This delights Tatenashi but as soon as he discovers that the place is a ramen cart parked under a rail overpass, Tatenashi is intrigued and asks if he does that everyone, but Ichika says “Huh ? No, this is my secret, I’ve only ever told the guys about it.” - this means that Ichika told his friends about this place but only the boys, and also that Ichika did not tell any girl she is friends with about this place and the village can include her sister as well. This makes Tatenashi the first and probably the only one who knows about this place from Ichika. And she is even able to pressure him into calling her his girlfriend in public.

Kanzashi Sarashiki

Tatenashi's younger sister and student from Class Four. Ichika asks Kanzashi to be his partner during the tournament at the IS Academy (Tatenashi asked him to do it). She initially despises him at first due to how others treated her in the past, to which slaps him thinking the offer is a bad joke. After that event, she starts to fall for him, so she finally accepts his petition.

Her feelings for him seem to be connected to her love for heroes. As such, Kanzashi views Ichika as her hero (someone who will always be there for her and protect her). At the end of Volume 7, she confesses to him. But because they were talking about anime, she believes (which is most likely true) that Ichika thought she meant anime and not him. She behaves like the other girls who love him do, shy when he compliments her looks, but will become angry with him when he compliments another girl.

However, her love for Ichika has changed her on a deeper level. Kanzashi is no longer reserved and shy about Ichika, and she continually schemes both with and against Tatenashi to reduce the amount of contact he has with other girls.

Maya Yamada

Ichika accidentally gropes Maya's breast, making him completely aware of them af

His assistant homeroom teacher in Class One and a former IS Representative Candidate of Japan. They have mutual respect for each other. Even when Ichika accidentally gropes Maya's breast during an IS demonstration, the latter does not seem to be too bothered about it ( even though she started daydreaming about the possibility of being Chifuyu's sister-in-law). The two would often find themselves in similar situations when they are training due to Ichika being in positions where he ends up noticing her large bust through her IS suit. Even during casual conversation, Ichika would find himself looking at her breasts whenever they jiggle. Maya doesn't get angry at Ichika like the other girls would, understanding that he's a young man and in age, thus she's often slow to notice. When Ichika ended up entering the mixed bath where Maya and Chifuyu were bathing nude, Maya didn't get angry at Ichika but was still surprised by his appearance, with both of them clearly flustered to have seen each other naked. Maya also helped Chifuyu hide him from the other girls by using their bodies.

Unlike Chifuyu, Maya tends to spoil Ichika at times and would take his side in matters. This includes hosting a contest for his birthday where she and the main girls, plus Chifuyu, wore revealing outfits for him and getting the 1st year personal pilots to serve him as geishas.

Honne Nohotoke

Honne comforting Ichika

The two seem to get along with each other, even before Ichika is forced into the Student Council. Ichika even recognizes her more out of all the other girls in the school outside of the girls he's usually with. His opinion of Honne is mainly on how she does almost everything at her own slow pace. Having gotten used to seeing her in her usually baggy clothes, he was somewhat surprised by how well-endowed she really was. Honne doesn't seem to mind being seen naked (or a least in her underwear) by Ichika as she takes her clothes off herself before him without any problems.

In volume 10, Honne won the right to sit next to Ichika on the train ride to Kyoto, where she enjoyed clinging to him the entire ride, much to everyone's jealousy. In order to get away from everyone crowding him, Ichika and Honne flew away, and they ended up in a play. After getting away from that, Honne took the time to point out to Ichika how he's always there for all of them, but didn't ask for the same from them. This ends up surprising Ichika as he cries. Honne comforted him by telling Ichika he could let them help him too. After this, the two start growing closer to each other, even outside of the Student Council, something that worries the Sarashiki sisters, especially after seeing him buy Honne a gift in a very casual manner.

Kaoruko Mayuzumi

A second year and the Vice-President of the Newspaper Club. Being the only male student in the Academy, Ichika has been interviewed by Kaoruko more than a few times. Because of this, Ichika has gotten used to Kaoruko, while often bothered by her teasing. In order to complete Kanzashi's personal IS, Ichika asked Kaoruko for help and agreed to her terms (going on a date with her).

Utsuho Nohotoke

Honne's older sister and fellow member of the Student Council. Due to her more mature and straightforward personality, Ichika would ask her for advice when it came to Student Council work or dealing with Tatenashi. Unlike the majority of the students, Utsuho never expressed or showed interest in getting closer to Ichika for being the only male there. Instead, she ends up dating his best friend Dan.

Ichika and Airis sleeping together.

Airis Twilight Ruxezemburg

The Seventh Princess of Luxembourg who first appears in Volume 12. She quickly took interest in Ichika after meeting him and had him as her escort around Japan, not giving him the choice to refuse. During their first week together, Airis kept ordering Ichika to do stuff for her whenever she felt like it. While Ichika found her to be a selfish little brat, he still did as he was told until it became natural for him. By the end of the first week, the two started warming up to each other, with Ichika beginning to see Airis as like a little sister, even giving her a nickname (Alice). Airis also starts to develop feelings for Ichika, and she wants to bring him to her home country to be with her, which only strengthens after he saves her from a kidnapping.

IS Pilots

Natasha Fairs

The IS Representative Candidate of USA and the pilot of the Silver Gospel. Natasha appears at the end of Volume 3 (does not appear in the anime) when she walks onto the bus (taking the IS Academy students back from their field trip) to look for Ichika. She was grateful to him for saving her from the out-of-control unit and kissed him on the cheek as her way of thanking him, unknowingly getting him into trouble with the girls. After kissing Ichika on the cheek, Natasha leaves the bus and talks to Chifuyu, only to blush when the latter teases her about her kiss, which has created unnecessary sparks.

Civilians from outside

Chelsea Blackett

Cecilia's maid and childhood friend. He first meets her in Volume 4 with Cecilia as his companion. The latter begins to suspect the rumor that 'Ichika likes older women based on the former's interactions with Chelsea. Unknowingly, this results in Cecilia pondering the possibility of becoming an older woman to get Ichika's attention. After the Excalibur incident, Chelsea is grateful to Ichika for saving her younger sister Exia, as well as them.

Ichika meeting Hikaruno

Hikaruno Kagaribi

The director of the Kuromochi Research Center where Ichika's personal IS, Byakushiki was developed. While Ichika tries to be polite toward her, Hikaruno's eccentric and perverted personality makes him feel uncomfortable around her. Like with Maya, Ichika often finds himself getting distracted by Hikaruno's large breasts, made easily noticeable by her IS suit. Unlike Maya, however, Hikaruno doesn't mind and makes no effort to cover them. Hikaruno finds him interesting and good-looking groping his butt before evening introducing herself. She would do it every time they met. Despite the age difference, she casually flirts with him and offers herself if he can't get himself a girlfriend. She invited him to her room for some 'fun' and suggested they could do sexual things (not even mind to say so in front of her coworker), something Ichika didn't agree with.

Phantom Task

Squall Meusel

The leader of the Phantom Task squad that Madoka and Autumn are a part of. The two first meet at the restaurant where Ichika and Houki are given free dinner tickets for. Since Ichika wasn't able to enter the restaurant without a formal outfit, Squall bought him one, so he could enter because she felt satisfied helping someone in need, along with roses for Houki. This leaves him charmed by both Squall's beauty and grace. However, he becomes confused when she says his name, even though he didn't tell her. He later learns that she's a member of Phantom Task, which leaves Ichika feeling more cautious of Squall when he meets her again while shopping, although he still acts polite towards her. This doesn't bother her much, and she warns him to be careful around his older sister and the Kuramochi Engineering's plans before leaving, causing Ichika to feel suspicious about the two. Despite being enemies, Squall doesn't have any personal grudge or open hostility about Ichika.
