Narue no Sekai

Fourteen-year-old Kazuto Iizuka is an ordinary boy until his classmate Narue Nanase saves him from an alien creature. He learns that Narue is half alien and that her father belongs to a team exploring the galaxy. Encouraged by his friend Masaki Maruo, Kazuto asks Narue on a date. Though hesitant at first, Narue agrees after Kazuto assures her that her alien heritage does not bother him, and they begin dating. Like any couple, Kazuto and Narue face problems. These include Narue’s alien sister, Kanaka, and Hajime Yagi, a classmate and ufologist who doubts that Narue is really an alien and believes she is pretending for attention.
