Hajime
Hajime is an amnesiac and a gluttonous girl who eats a lot and often. She spends most of her time at the Nowhere Café.
She suffers from memory loss. At first, she seems ordinary, but her minimum is revealed to be enhanced speed, strength, and regeneration. It is not explained how she activates her minimum until the second season (Re: Hamatora).
