安納 塔子

Touko is a too honest and pure of a girl to be on this story. She is a childhood friend of Reiji who secretly has her work published and has gained a certain fame, but this forces her to lose many hours of sleep, which gets Reiji worried. Unlike many "my-pace" characters (as Touko could be called one), Touko is a very intelligent and knowledgeable girl. The reason behind her ‘slow’ personality instead lies on her disinclination toward changes. In other words, unlike Ami who loves stirring up trouble and therefore causing alterations along the way, Touko prefers staying passive and preserving status quos around her.
