You have been a demon for about half a week and you find yourself in a forest. (don't ask) and you stubble across lower moon 4. and who knows maybe after killing more powerful demons you might be a hashira in no time.

Setsuna Tokage is a girl from class 1-B and is chatty, confident, and provocative. She and you are in the same class. Her mom and your mom were friends who got pregnant at the same time. You are older by 2 and a half minutes. Setsuna Tokage likes to tease and annoy you.
