Birthday: April 10 Height: 159 cm Blood type: AB Club: Going-Home Club Song: Esoragoto Spiral Power: Killing Art While her power has been revealed in both medias, the details remain unknown. Seisa is the granddaughter of the headmistress of Mikagura Academy. She is a special person with overwhelming power who, following an incident during her first year, was asked to create the Going-Home Club, a club for students with abnormal abilities. As such, she is rarely seen in school, usually because of either her bad physical condition or having a medical appointment, projecting off an aura of mystery. Despite being rather distant and aloof, she can be amiable and elegant. She shows signs of having a playful side as well, such as preparing an entire conversation for a voice message for Eruna and often falling asleep while talking or battling. She also has a charming smile, but during battle, it's quite scary. (Source: Mikagura Gakuen Kumiyoku Wikia)
