Summer Azusa Kinose ( 木ノ瀬 梓, Kinose Azusa) Voiced by: Jun Fukuyama Azusa represents Sagittarius. Beneath his warm exterior, Suzuya has a dark side and worries about Tsukiko constantly.

Suzuya is also in love with Tsukiko, but because he knows that Kanata also loves her, he held back. He is very good at cooking and often uses the school's kitchen to prepare food for his friends. Calm and friendly, he was friends with Tsukiko and Kanata since childhood and often watches out for them like an older brother.

However, he refuses to seek medical help and often gets into school fights that worsen his health to protect Tsukiko. Kanata suffers from a terminal illness that leaves him in a lethargic state, which is why he often skips classes and faints without reason. He does not get along very well with Yoh. Brash and impulsive, he has been friends with Tsukiko since childhood and has developed feelings for her. Kanata Nanami ( 七海 哉太, Nanami Kanata) Voiced by: Tomokazu Sugita Kanata represents Pisces. His father hopes to work in America to develop a special astronomy project. Initially disdainful to everyone except Tsukiko, eventually, he learns the importance of having friends. He met Tsukiko when he was young, and because she was the only person who didn't make fun of him for being half-French, he fell in love with her and asked his father to let him transfer to Seigetsu Academy in order to pursue her. Likewise, he is half-French and was often teased for that as a kid. His French name is Henri Samuel Jean Aimée.

In the third game, Starry☆Sky~in Autumn~, Tsukiko becomes involved with three teachers at her school (Iku Mizushima, Naoshi Haruki, and Kotarou Hoshizuki). As she practices for the summer competition, she simultaneously solves the problems between her teammates (Homare Kanakubo, Ryunosuke Miyaji, and Azusa Kinose). In the second game, Starry☆Sky~in Summer~, Tsukiko has joined the academy's archery club. This action stirs up emotions from Kanata and Suzuya, both of whom had long loved Tsukiko. In the first game, Starry☆Sky~in Spring~, not long after Tsukiko transfers to Seigetsu Academy, a half-French boy named Yoh Tomoe follows suit to pursue her. Throughout the games, she befriends other young men whose personalities are based on the Western zodiac constellations. She is closely watched over by her childhood friends, Kanata Nanami and Suzuya Tohzuki, who often protect her from the male student body.
