Hajime Yagi (八木 はじめ)

Yagi is a classmate of Kazuto's and a sci-fi enthusiast. She doesn't want to believe Narue is an alien, so she acts hostilely towards her early on. When she befriends Kanaka, who had trouble adjusting to school, Yagi is shown to be somewhat of a loner. Yagi and Narue eventually get over their misunderstandings, partly due to Kanaka, and are able to become friends.
