寄忍 由良利

Yurari is the older cousin of Seiji and Yume and the childhood friend of Karin, Jun and Atsu and the friend of Mitsu. She is also their teacher.

Yurari is currently learning to be a teacher, it's her childhood dream. She tends to speak slowly while taking breaks with her friends but begins to speak normally in front of the rest of the world. She is very close to Seiji since always, always to cuddle him as if he was a plush, their proximity is such that Seiji once confessed his feelings but she never gave him an answer.

She is idolized by the whole school where she works, but she doesn't know why.

She has a lifestyle that is usually completely neglected, she only wears tracksuits, does not tidy her apartment and Seiji greets with just a towel to cover herself. 

She hardly feels shame, being naked in front of Seiji doesn't bother her.

Whether Yume or Seiji or whoever else, everyone thinks that she is not a virgin since a long time, because she is very pretty and very kind.

She is very assertive, when Seiji decides to take an interest in Yurari again, it is she who takes the lead by masturbating him in the bathroom./
