コロナ

Full name: Asaumi Korona (浅海 ころな)
Likes: Humans
Dislikes: Causing trouble

A robot produced by the Valhalla Institute with the hope of one day being sent into space to explore far-off planets. In order to become accustomed to human culture and becoming more similar to them, she attends Tsukikou. She is very friendly and speaks overly polite to everyone. She’s very enthusiastic about making friends with everyone to the point where she wants to know the names and faces of everyone who goes to Tsukikou. However, she’s afraid her being a robot scares people away from her. She often helps her friend Rui out at the local shrine.

She was actually born as a normal human girl and awakened as a very powerful Elfin and can use a multitude of runes. Her specialty is pyrokinesis.
