Eriko is an obsessive girl who is infatuated with Yuuki, often going to large lengths to gain his affection. She is shown to be drastic and manipulative, akin to that of a Yandere. With few exceptions, she is often dismissive of the people around her.
However, she has a kind and almost motherly side to her shown almost exclusively to children.
