Description
Otome Katou is a secondary character in School Days. She is a first-year student in class 1-4 of Sakakino Gakuen and a classmate of Kotonoha Katsura. She has been a friend of Makoto Itou since at least middle school, and the two share a long history as childhood acquaintances. Otome is a member of the girls' basketball team and acts as the de facto leader of the girls in her class. She has brown hair and brown eyes, and she stands about 164 centimeters tall.

In terms of personality, Otome is direct, headstrong, and assertive. She is comfortable taking charge of her social group and is regarded as its organizing figure. Despite her confident outward manner, she carries a long-held crush on Makoto that has existed since junior high. This attachment is one-sided, as Makoto does not appear to think of her romantically. When Makoto begins dating Kotonoha, Otome becomes strongly irritated and jealous, particularly because she had previously assumed that his interest in her was one-sided.

Her primary motivation is her desire for Makoto's affection and recognition. She wants to be close to him and is deeply unsettled by the idea of another girl taking the place she hoped to occupy. This jealousy drives her to act against Kotonoha. In the story, Otome is responsible for the bullying that Kotonoha endures, using her influence as the leader of the class's girls to turn others against her classmate and rival.

Within the story, Otome serves as a supporting figure whose actions intensify the tensions surrounding the central romantic conflicts. Her connection to Makoto and her involvement in Kotonoha's mistreatment place her at the center of the emotional fallout that affects the main characters. In the original visual novel, she has her own route in which her relationship with Makoto can develop into a genuinely happy one, offering an alternate outcome in which her long-standing feelings are finally acknowledged and returned.

Her key relationships are with Makoto, Kotonoha, and the group of girls she leads. Makoto is her childhood friend and longtime crush, while Kotonoha is both her classmate and her romantic rival. The other girls who follow her are the ones who carry out the harassment she orchestrates. In the anime, her situation does not change substantially, and her feelings for Makoto are never fully reciprocated. In alternate story material, however, she has the opportunity to move past her jealousy and build a real relationship with him.

Her notable abilities include her athletic skill as a member of the girls' basketball team and her social influence as the leader of her class's girls. She uses this influence to maintain her social standing and, negatively, to organize the bullying directed at Kotonoha.
