Maya Yamada (山田 真耶, Yamada Maya?) is the assistant homeroom teacher of Chifuyu Orimura in Class One at the IS Academy and a former IS Representative Candidate of Japan.


Maya has short green hair with matching colored eyes and wears glasses. While being around average height and somehow petite, she has a voluptuous figure and very large breasts, which are made more noticeable whenever she is in her tight-fitting IS suit. She is mostly seen wearing a revealing short sleeves yellow dress with black edges that shows off much of her pink (black in the CHOCO illustrations) bra and knee-high black boots. For practices and missions, she wears the standard IS suit. During the practice for Cannonball Fast, she wore a custom IS Suit that had a V-neck, but she was forced to stop wearing it because it was too distracting Ichika. 


Maya takes being accidentally groped by Ichika surprisingly well

Compared to the confident and harsh Chifuyu, Maya is usually a very shy and nervous person who is highly affectionate towards her students. For example, when Ichika accidentally grabbed her breasts during a crash landing, she refused to say anything cruel or mean. Instead, she began talking about marriage and the implication that Chifuyu would become her sister-in-law and whatnot before having a sexual relationship. Ichika quickly backed off due to his somewhat similar personality. She is a sharp contrast when compared to Chifuyu, who tends to be very strict and hard with her students. This doesn't mean she isn't capable of being strict with them when they get out of line. Despite her tremendous IS abilities, Maya remains extremely modest when being flattered by Chifuyu, stating that it was ages ago and that she never got past being a candidate student.

She can be quite mischievous and teasing from time to time, such as playfully questioning Chifuyu about her brother, which she is always forced to take back under the threat of sparing with her. She also enjoys putting her old rival Djbril in an embarrassing situation by taking advantage of her prideful and rash habits. This dated back to when they were students themselves.

Despite her shyness, Maya can quickly become level headed and confident when it's time for action. This quick change surprised her students, after she protected Ichika from Cecilia and Rin's anger. She is also somewhat playful in battle as well, as she can often be seen smiling when in action. Furthermore, Maya is surprisingly brutal as well, as she would bombard her opponent with bullets without giving them any chance to escape, which earned her the nickname "Killing Shield", something she's embarrassed by. 

Maya being slow to notice a Ichika's "problem"

Maya is also rather inexperienced when it comes to being around males. Often, she's slow to catch on that her large breast would naturally draw the attention of young boys (usually Ichika), especially when she's wearing the skin-tight and revealing IS suit. When she does finally pick up on this, she surprisingly gets very shy about Ichika noticing her breast but has never gotten angry at him for it, suggesting that she might be a little happy with the attention. She admits at one point that she has never had a boyfriend, which further explains her inexperience. She has trouble understanding some of Ichika's discomfort with women, such as when he was put in charge of taking the students' measurements.

Similar to Chifuyu, Maya cares a lot about her students as a teacher. She always expresses strong concern for them during emergencies and would prefer they avoid putting their lives in danger. Even in situations where she and Chifuyu have needed to send them out, she regrets that they had to, preferring not to as a teacher.

Infinite Stratos & Abilities

Despite her fragile personality, as a member of the IS Academy staff, Maya is highly proficient at manipulating an IS. Chifuyu, a legendary IS pilot acknowledges Mayas' abilities. Her extremely accurate sharpshooting skills makes her a highly skilled opponent. During a demonstration, she easily defeated Cecilia and Lingyin in a 2 vs 1 battle while using a 2nd generation mass produced IS(although modified) against their 3rd generation personal IS. Maya is also very nimble and can quickly dodge attacks easily. Using her personal IS, Show Must Go On, she was easily able to defeat the Shirokishi while it was controlling Ichika (thought she did only appear after it/he had already fought Madoka and the other first year personal pilots).

Maya's fighting style seems to resolve around forcing her opponent(s) into a corner before finishing them off with one powerful attack. Using her personal IS, she would trap her opponent with her shields then bombard them with bullets. These tactics are what likely earned her the nickname Killing Shield. Despite her slender figure, Maya is surprisingly strong.

Maya demonstrating her sharpshooting skills

Maya's IS is the Raphael Revive from the Dunois company. It's a machine developed at the end of the 2nd Generation, but its specifications are on par with the early 3rd Generation machines. In terms of deployed mass production IS models, it went on sale the last, but has the 3rd largest buyer-base in the world. By changing the the equipment, it can be configured for all types, including physical combat, sniper role, and defense.


Not much is known about Maya's past except that prior to the start of the main series, Maya used to be an IS Representative Candidate of Japan. However, she never got past becoming a candidate student.

The second volume of the light novel identified her as the instructor who Ichika "defeated" during his entrance exam.
