Мінасе Акіко

Akiko is Nayuki Minase's mother and Yuichi Aizawa's aunt whose main role is in Nayuki's arc.

Akiko is a kind and caring person. She is a great cook and is proud of her special and unique jam, which no one likes. It's unknown if she has tasted it or if she likes it. She tends to answer yes and no very quickly, usually in one second. She works at an unspecified job and takes care of the house, cooking various types of food, most of which is good except for her infamous "special" homemade jam which she alone enjoys the taste of. She appears to not realize exactly what is going on around her, taking in strays such as Makoto Sawatari and assuming lame excuses for her behavior. Akiko is known to be very easygoing and is constantly smiling.

She will not even resort to stern lectures, such as when Makoto spends money on herself that Akiko gave her to buy food. Akiko can be assertive, though she never has once raised her voice in anger or otherwise. She will often give responses to questions within one second of being asked, the answer almost always marking approval.
