Tsumugi Wakana from "Puella Magi Madoka Magica: Magia Record" by nanihoo

One of the side characters from the Magia Record online game, Tsumugi Wakana is a girl whose only desire is to eat and praise good cooking. To that end, she makes a wish to keep supporting fellow magical girl Manaka Kurumi.

I've been fond of Tsumugi's design for a while, and even though others consider it too plain I feel it makes sense if she wanted to support another magical girl. It's simpler compared to others because you don't want to overshadow the person you're trying to help.
