Club: Going-Home Club
Song: Esoragoto Spiral
Power: Killing Art
Seisa is the granddaughter of the academy's headmistress, which basically explains her status as someone operating on a completely different level than most students. She's best known for her overwhelming power and the mysterious circumstances surrounding her first year—something happened that led to the creation of the Going-Home Club specifically for students with abnormal abilities, with her at the helm.
You rarely see her around campus, partly because of chronic health issues and partly because she's constantly dealing with medical appointments. This absence has only added to the air of mystery surrounding her.
On the surface, she comes across as distant and aloof, but there's more going on beneath that. She's genuinely elegant and charming when she wants to be, and fans often note her playful streak—like the time she prepared an entire voice message conversation just to mess with Eruna. She has a tendency to fall asleep mid-conversation or mid-battle, which is pretty on-brand for someone with her condition. Her smile is genuinely disarming in normal situations, though during combat it takes on a different, somewhat unsettling quality.
