Agari Yamato's beautiful, slightly neglectful mother.
She is 32 years old and the mother of Agari Yamato. Cconsidering both her and Yamato's age, she was a teenager when she gave birth to him (about 16 years). She is very short-tempered and doesn't like when Yamato behaves strangely. She is first seen when he was hiding in the bushes, simply warning him not to use the restroom in them and leaving, unconcerned as to why he was there in the first place.
She seems slightly neglectful, dissappearing for periods of time and then showing up again; it appears that Yamato is used to this, as her reappearance eludes any special reaction from him. When he was a child, she at least cared enough to walk him to his first day of school, and mentions how she always buys him milk (his favorite food) when he wants it, although she warns that it's going to make him too big and expensive to feed -- which did eventually happen.
