Infinite Stratos Wiki

Lingyin Huang (凰 鈴音ファン・リンイン, Fan Rin'in?), nicknamed "Rin", is a first year student at the IS Academy. She is also the second childhood friend of Ichika Orimura. She is the third heroine to be introduced in the Infinite Stratos series.


Rin is a young, petite teenage girl. She has light brown hair tied into long twin tails, with a yellow ribbon at both sides. She has green eyes and her fangs could often be visible.

Rin's IS Academy uniform is slightly modified as the sleeves are detached and expose he shoulders. For her IS practices and battles, she wears a pink version of the training uniform.


Rin is depicted as a very energetic girl with a slight competitive streak. This is seen when Houki and Cecilia were arguing with Lingyin about her relationship with Ichika. She effectively answers them while hinting that she has an advantage over them (e.g. when Houki said that she has eaten and slept with Ichika when they were kids, Lingying said that he has been coming over to her place to do the same when they were in grade school, though Ichika is quick to clarify by saying he ate at the restaurant her family owns).

In her middle school year, Rin was usually the target of pranks due to her nationality. However, Ichika helped protect her from these situations (e.g. when he protected her from four school bullies). Because of this, she developed romantic feelings for him and made him promise that if she became an excellent cook, he would become her boyfriend. When she meets Ichika again at IS Academy she becomes disappointed and extremely hostile to him because he had forgotten the details of the promise. When he asks what she means, she just says that it means she will give him free meals, hoping he would not understand the meaning, which is technically a lie.

Lingyin is very impulsive and irresponsible, as she always acts without thinking about her action or the problems with them, which is made worse by the fact that she has a personal IS. This often causes headaches for her superiors in China because of the trouble she usually causes as an IS Representative Candidate. She rarely acknowledges her actions as her fault (which they are) but instead's blames someone else (mainly Ichika). Like Houki, she has a tendency to be self-righteous of her actions. She can also act very aggressively when is provoked enough.

She can become extremely jealous when there are other girls around Ichika who are trying to get his attention, to the point of showing the stereotypical lifeless eyes of a "yandere" girlfriend (this trait is shared with Cecilia in episode 9 and at the end of episode 12). This trait is also seen at the end of episode 8, when Charlotte revealed that she is a girl. Rin crashed into the classroom and was immediately about to shoot Ichika with her Shenlong's Ryuhow without giving him time to deploy his own IS. Similar to Houki as she's also his childhood friend, Rin's cruelty towards Ichika hinders her from getting closer to him (meaner than Houki to be precise). However the case may be, Lingyin highly expected Ichika to notice how she feels about him, but she keeps her true feelings a secret. Despite being the same age as Ichika, Lingyin's too immature to give him a chance to bond with her, which also hinders her from getting closer to Ichika, despite them being childhood friends. This was displayed when she was under World Purge, as her ideal version of Ichika expressed his feelings for her while trying to make physical advancements on her whenever he had the chance, which she was happy with despite saying otherwise.

Lingyin is very sensitive when it comes her bust size. She can become easily enraged when her size is mocked or pointed out by others. Her friends are aware of this and try not to talk about it, as she becomes threatening even when there's no ill intention. Strangely, she usually brings up this topic when she starts thinking about it or notice other girls' breasts. In Season 2 Episode 5, she became enraged and jealous when she saw Ichika look at Charlotte's breasts, believing he was only focused on them (Charlotte's breasts).   

Similar to Cecilia, Lingyin has shown to a lewd imagination when it comes to Ichika. Often, she would imagine him having a strong desire for her and making advances on her. Sometime, she would mix up her delusion with reality, embarrassing herself when she realizes what she was thinking.   

Infinite Stratos & Abilities

Ling performing a partial deployment

Lingyin is supposedly skilled in her piloting of her Personal IS, as she has the same rank as Cecilia. She has good combat senses when it comes to 1-1 combat, but tends to underperform at times when she loses her temper. She also received military training.

Lingyin is also able to quickly perform a partial deployment (summoning a part of the IS), first seen when Houki tried to hit her with a wooden kendo sword.

Outside of combat, Lingyin is skilled at cooking, mainly Chinese cuisine. This is because her family used to run a Chinese restaurant.


Ling and Ichika on the day of the Sweet Pork promise

She moved into Ichika's neighbourhood soon after Houki's family moved out. (Houki moved out at the end of 4th grade, and Lingyin moved in at the beginning of 5th grade). Her family used to run a Chinese restaurant, which Ichika visited frequently. During this time, Chifuyu spent most of the time outside working due to her prominence as an IS pilot, and Ichika decided to go out to eat rather than cook for himself.

Due to her nationality, Lingyin became a frequent target for pranks. She seems to have developed a crush on Ichika when he helped her by fighting against four kids bullying her at school.

She moved back to China during early 3rd grade of junior high, due to her parent's marital issue (they are now divorced), but transferred to IS Academy as a Representative Candidate for China.

Episode 8: "Find Out My Mind"

Cecilia and Lingyin are in the crowd to watch the long awaited battle.

The fight has started and Ichika immediately goes on to strike first at Laura, but is stopped by her AIC. As Laura prepares to shoot Ichika while he's paralyzed, Charles appears behind Ichika and counter-attacks Laura with her Rapid Switch, but Houki interferes, stating that she won't have them forget about her. Laura feels that Houki is in her way, so she used her tentacles to remove her out of her business against the boys. While Ichika and Laura fight, Charles defeats Houki first and resumes his battle against Laura.

During the fight, they discover the AIC's weakness: Laura can only focus on stopping one enemy per time. They then use different "sacrifice-and-attack" combos to slowly defeat her. Ichika gets his energy shield exhausted and Laura takes advantage of this to pin him down to the ground, but Charles keeps protecting him with her Ignition Boost, stating that it's the first time he's using it. Charles then uses her Shield Pierce weapon to brutally punch Laura's shield multiple time and exhaust her armor. Laura, fainting, is suddenly consumed by her IS and transforms into a large dark mech that matches Chifuyu's fighting style. Angry about this, Ichika decides to fight against it, but Houki holds him back, telling him that he doesn't have to do anything and the matter will be resolved by the instructors troop. Ichika still refuses and Charles offers him enough energy to manifest his sword, making him promise that if he loses, he'll have to wear a female uniform to school starting the next day, embarrassing Ichika and Houki. After Ichika gets enough energy, he cuts through the mech and saves Laura.

The next day, Charles introduces herself to the class under the name of "Charlotte" Dunois, shocking the whole class. As everyone knows that Ichika and Charlotte used the Boys' Bath the night before, Lingyin charges into the class with her IS to attack Ichika, probably jealous that he bathed with another girl instead of her, but is stopped by Laura's AIC. Ichika thanks her, but is suddenly grabbed by Laura as she French-kisses him in front of the whole class, shocking Cecilia, Lingyin, Houki, and all of the other girls. Laura then states that Ichika will be her bride, saying that it is final and that she won't hear any objections from him. Ichika and the girls are once again shocked.

Episode 9: "Ocean's Eleven!"

Lingyin and Cecilia, along with Laura, stalk Ichika and Charlotte through the shopping mall to learn about their relationship. While looking for Charlotte and Ichika, who have disappeared into a swimsuits boutique, they spot Chifuyu and Maya giving them a moral lesson in the middle of the boutique about drawing a line even as classmates.

At the beach, Maya tells everybody to enjoy themselves and to return to the inn in time for dinner. When Honne asks Ichika to play volleyball with her, Lingyin jumps on Ichika's neck to play walking watchtower, which Ichika hates. Cecilia arrives and asks Ichika if he had forgotten about the promise he made to her on the bus, which is to rub suntan oil on her back; he agrees desperately. Hands full of suntan lotion, he touches Cecilia's naked back (without her bikini top attached) and she screams, saying that he must warm up his hands before he rubs. Ichika then warms up his hands and rub her back while Cecilia enjoys the sensual massage. When Ichika's done, she asks Ichika to rub everything where her hands don't reach, including her legs and butt. Ichika freaks out and Lingyin takes the oil and replaces Ichika. She rubs it in a tickling manner that makes Cecilia giggles the whole time. When Lingyin rubs her butt, Cecilia gets up to scold Lingyin, but her top falls off, exposing her breasts. Ichika freaks out as he gets punched in the face by Cecilia's partial deployment IS.

Later in the water, Lingyin challenges Ichika to a race to the buoy and that if he loses, he'll have to treat her to shaved ice. As she swims underwater, she starts to drown. In the anime, she has a leg cramp; in the LN she accidentally swallows water instead of air while getting distracted by her thoughts. This forces Ichika to save her and pull her to the shore. Cecilia then proposes to walk her to the inn as she got "hurt". With the help of Shizune Takatsuki, they drag Lingyin by force towards the inn as she resists.

While everyone's playing volleyball, Cecilia is seen chasing Lingyin. Lingyin runs into Chifuyu's breasts and both of them get scolded. They then have fun on the beach for rest of the day, Cecilia sun tanning and Lingyin playing in the water.

  • Lingyin's name in kanji means "sound of the bell". Bell (Ling, 鈴) and Sound (yin, 音). Her name matches her loud voice. In Chinese, her name literally means "Phoenix Ringtone".
  • Among the 5 girls in Ichika's harem, Lingyin has the lowest rate of public appearances.

    • Both are stubborn, prideful, impulsive and good cooks.

    • Both are rather boyish and, as a result, both like it when Ichika looks at them as girls.
