|Japanese name:||彩京 朋美|
Tomomi is an upper-ed student at the academy and is also Hino's childhood friend. Her polite and refined attitude serves as a front to hide her true self: a manipulating prankster. She plays pranks on other people to keep herself from being bored and is willing to withhold information from everyone whenever she sees fit. Also there may be some cases where she involves others in situations to achieve certain ends (as when she assigned Hino to stay with Mimina for a day in order to inspire her to draw).
According to Hino, she is highly intelligent and also dislikes losing to other people. In the anime, a characteristic high-pitched giggle accompanied by a shadow and dark expression on her face signify whenever she is having an evil thought. It is revealed by Hino while she and him were on a date that, despite her constant pranks on him, he had in fact had a crush on her and his dream was to marry her when they grow up, which surprises and embarrasses Tomomi, showing that she reciprocates these feelings but never realized it until then.
