In real-life, Chika Tatehara is a girl with self-confidence issues. Considering herself unattractive, she becomes the magical girl Pechka in order to confidently talk to her crush and give him food.

Pechka's ability allows her to turn any object into delicious-tasting food after maintaining contact with it for 5 minutes.

In cyberspace, Pechka is a member of the party "Team Clantail" along with Clantail, Rionetta and Nonako Miyokata. As her ability is unsuited to combat, she and Nonako often scout while Clantail and Rionetta grind for items by defeating monsters.
Despite this, Pechka is a valuable asset to the team, as her meals boost their morale. This makes her very happy and gives her more confidence.
