Natsume Sakuya

Akira and Kurumi's childhood friend. She took care of them both after their father died while their mother went to work to support them. Because of this, they both often call her Nee-san. She is strict toward Akira, so Kurumi will often tattle on him to her. Her alternate reality self is good friends with Miruku and is also a magical girl.

She has strong magical powers, but doesn't know how to control them well. This often leads to unintended side effects to her magic.
