Description
Koi Kisaragi represents February in the Tsukiuta franchise as an idol under Tsukino Talent Production and a core member of Six Gravity. He possesses fair skin, short bubblegum-pink hair, and slightly darker pink eyes, often adorned with hairpins from his younger twin sister, Ai. Though initially one of the shortest idols across both Six Gravity and Procellarum, he grew significantly, reaching 176 cm. His theme color is pink.
Naturally friendly, amiable, and socially adept, he forms connections easily and encourages others. Earnest, hard-working, and straightforward, his broad knowledge fosters unexpected relationships. Within Six Gravity, he acts as a mood-maker, playing the funny man while delivering sharp retorts, making him a reliable presence. Despite appearances, he possesses a strong moral sense. His extroverted nature helps him connect with staff, and he often assumes a protective, brotherly role towards others, even while being doted on by older members.
He is the older twin in a family where his mother is a former goddess and Ai is a goddess candidate; neither he nor his father knows about the Moon Society or the goddess status. Scouted at 15, he debuted and moved into the TSUKINO Dorms with Shiwasu Kakeru, Mutsuki Hajime, Yayoi Haru, Uduki Arata, and Satsuki Aoi, forming Six Gravity. The announcement of rival sibling unit Procellarum initially shocked him, leading both units to pursue idol work side-by-side yet individually.
Relationships are central to his character. He deeply cares for his sister Ai, though others perceive her as more dependable. His closest bond is with Shiwasu Kakeru, his missionary school classmate; they became instant friends and are frequently paired. Koi's natural good luck balances Kakeru's misfortune, creating equilibrium. They established rules for shared responsibilities like walking their dog Croquette and have experienced conflicts typical of their closeness. He intensely respects Mutsuki Hajime, likening him to a "final video game boss" and accepting Hajime's strict tutoring, particularly in English, which significantly improved his grades. His dynamic with Uduki Arata involves frequent bickering over trivialities due to similar wavelengths, though they share underlying compatibility noted by others. He admires Satsuki Aoi's good looks without his usual dislike for "high-spec" people, viewing Aoi as an older brother. He also enjoys spontaneous conversations with Procellarum's Haduki You.
In the anime's second season, he undertook a clothing design project for a women's magazine, tasked with creating "clothes that make you smile." His initial design received praise but felt incomplete; a comment from Ai inspired a redesign, leading him to collaborate with Kakeru and You to refine the concept. Earlier episodes show his proactive organizing, like when he and Kakeru filmed member comments for the Full Moon Festival 2020 concert, handling scheduling and locations. His growth is reflected in merchandise like a compact mirror featuring his likeness and character CDs, including duets with Kakeru exploring their contrasting yet complementary dynamics.
