ここあ

Kokoa is a manager of a supermarket. She views convenience stores as inferior to supermarkets, and because of this, she comes off quite hostile to Chris at first. 

Kokoa is semi-hidden romanceable character, though her level of interaction otherwise would be indistinguishable from a minor character. She is not listed among the official main characters on sites like Getchu, but does have her own character image and scene reminiscence section./
