Keila

Keila is a recruitable character that can be found in the abandoned church at Straight Down City, by continue moving right after finding Beatrice's house. To recruit her you need to give Maria a scroll of light, summoning her. If you keep using light scrolls, Keila will get new skills until she has nothing else to learn, being maxed out and changing her appearance. She is the only angel in the whole game, and there is no explanation why.

Her quirk in battle is making miracles, healing allies and even reviving the dead. She also has damaging magic skills.

The game itself described her as:

"Pretty nice angel that helps who's in need. Kinda refreshing to see one in this world."
