Nagi Amano

天野凪 天野 凪（あまの なぎ）

Gender:Male

Nagi, Hina's younger brother, is a fifth grader. Initially, he held a negative impression of Hodaka being with Hina, but quickly warmed up to him when Hina started her "Sunshine Girl" service. He also made friends with Moka, Keisuke’s daughter, the day they first met. During the "Sunshine Girl" service, he wore a mascot costume modeled after teru teru bozu, designed by Hodaka, although he initially disliked it. In a selfie shown by Keisuke to Hodaka at his office, featuring Natsumi and Moka, Nagi can be seen in middle school, noticeably taller. Characteristics/Personality: Due to his extensive romantic experiences, he speaks with a maturity uncommon for someone his age. Yet, he possesses a childlike side, genuinely worrying about Hina. He is lively and able to get along with anyone, as evidenced by a scene where he gives Fumi a shoulder massage. Hodaka calls him "Senpai" for his advice on dealing with girls, while Keisuke and Hina call him "Nagi," and Natsumi, Ayane, and Kana refer to him as "Nagi-kun."
