Asou Asuna

An older girl that works at the local cake shop. Asuna is generally amicable and is very willing to give advice (and is somewhat romantic). She instantly takes a liking to Kida upon meeting him, and vows to protect and look after him. Though she seems to be quite comfortable with the role of "older sister" leading the "inexperienced younger man", her demeanor changes to that of a tense and quiet person whenever her past is brought up.
