Natsume Koyomi

Koyomi is the student council president of Seikai Academy and the leader of Star-Crossing Circle. Koyomi is cursed with “Sloth”. Her curse is the most dangerous because at any time and anywhere, so long as it triggers, she falls asleep whether she likes it or not. When she isn’t sleeping or up on a tree, she is usually marveling at the mathematical wonders of the world.
