Katya likes angels and she have a few favorite ones from video games and other media, this one is Angel from ActRaiser he is the angel that players control during the town building parts of the game killing demons and getting orders from Lord of Light or God (name in the Japanese version) to build the town and find demon nests, in the Renaissance remake of the game it he can only assist in giving orders to "The Champions" and places where the players will used the miracles to kill the demons invaders.

Anyway she is just here hugging the little guy must go flying to kill demons to save people from a town... maybe is Bloodpool.
