Narue no Sekai

Kazuto Iizuka is a 14-year-old boy whose life changes when he encounters Narue Nanase, a classmate who rescues him from an alien attack. He learns she is half-alien, with a father involved in a galactic exploration team. Encouraged by his friend Masaki Maruo, Kazuto invites Narue on a date. Initially hesitant, Narue agrees after Kazuto reassures her about her heritage, and they begin dating. Their relationship faces challenges, including Narue’s alien sister, Kanaka, and Hajime Yagi, a classmate and ufologist who doubts Narue's alien identity, believing her to be seeking attention.
