Hajime Yagi  

, 八木 はじめ

Yagi is a friend of Kazutos and enjoys science fiction. She initially refuses to accept that Narue is an alien because she doesn't want to believe it. Later on, when she meets Kanaka, who struggles with adjusting to school, Yagi appears to be somewhat isolated. Eventually, Yagi and Narue reconcile due in part to the influence of Kanaka, and they become friends.
