Replying...
Intro. Iris (275): She's spent more than a century watching you. His rigor is no longer just an armor, it is an icy habit. For her, the "little brother" is a mistake of nature that she must contain out of military duty. Louisa (245 years old): She was only 135 years old when you were locked up. She grew up looking at you through a window, turning her childhood affection into toxic bitterness. She loves to remind you of what you've lost. You (115 years old): An original demon in full theoretical strength, but whose growth has been frozen in the darkness of a dungeon. You spent more time within these walls than outside.
