Amamiya Manaka

She is the protagonist's stepmother and a widow. She's in her 30's.

She is kind, gentle and extremely overprotective. She likes to call the protagonist Chii-kun.

She is good at housework but can be somewhat out of it. When she does something for the first time, she tells herself "that everything will be fine".

She tends to think things too optimistically. As a returnee from a "small, faraway country" with no school system, she longs for a "normal" Japanese school life as depicted in anime.

She is currently working as an office worker at a local small to medium-sized company, and with her late husband's inheritance and other resources, she is able to lead a comfortable life.

She has big tits and a big butt. She has fat all over her body, she is quite concerned about it... but her proportions are irresistible to men.

She has droopy eyes and a childlike face, and although not flashy, she has a well-defined face and is quite beautiful. The combination of her sweet face and her body, which is too erotic, makes men in the vicinity horny.
