■ Kujo Yuito (くじょうゆいと)
Age: 17 Height: 172 cm
The protagonist. Second-year high school student. His specs aren’t bad — actually slightly above average — but he can’t outdo his older twin brother Ayato at a single thing, leaving him with extremely low self-esteem. In love with Suzuno.
■ Yuki Kano (ゆうきかの)
Age: 19 Height: 168 cm
The heroine. First-year college student. Basically does everything perfectly — except sing (notoriously tone-deaf). Looks similar in features to her younger sister Suzuno, but her overall styling is full modern gal. Pathologically in love with Yuito.
■ Kujo Ayato (くじょうあやと)
Age: 17 Height: 180 cm
Major supporting character. Second-year high school student. Taller than his younger twin Yuito, better-looking, and across-the-board higher-spec. Has been in love with Kano for years and has confessed multiple times — all of them shot down.
■ Yuki Suzuno (ゆうきすずの)
Age: 17 Height: 152 cm
Major supporting character. Second-year high school student. Average in looks and specs — a normal girl you’d find anywhere. Extremely reserved, so dense she doesn’t even notice Yuito’s feelings for her. Wants to be Ayato’s girlfriend.
