Setsu

Despite looking very young, Setsu actually hates being treated like a kid; which is ironic considering she's very immature and spoiled. Costumers and coworkers alike appreciate her youthful charm and little sister type personality, but her innocence is a bit of a double edged sword in the sense that it also makes her prone to being insensitive, being able to mercilessly throw insults at others without realizing the effect her words have on people. Her dream is to become a pastry chef.

Spoiler

Her real name is Kasuga Yuki (春日 雪).
