Seventeen-year-old Kantarō Misuji balances high school life with membership in the idol rap group VISTY. He projects a bright, energetic, and cute persona for fans, yet his self-worth depends entirely on social media validation. He lives and dies by online metrics—likes, comments, follower counts—compulsively checking notifications and tracking VISTY's search trends. This obsession fuels hashtags like #LikesAreMyLife and #FollowerCountIsMyLifeWorth, cementing his belief that attention equals existence value. His appearance is striking: asymmetrical blonde hair boasts multicolored tips (pink, orange, yellow, green, purple), and his heterochromatic eyes swirl pink, purple, blue, and yellow. Flamboyant fashion defines him—a pink jacket over a striped shirt, rainbow-patterned pants, mismatched socks, plus beaded necklaces and a bucket hat. His phantometal, the Melancholic Smartphone Case, activates when kissed and visually manifests his digital validation link. Kantarō's background shaped this drive: abandoned by parents who moved overseas at age four, he was raised by grandparents in rural Japan. He entered idol training school at 13 but dropped out, only to be scouted by his current agency at 14. Debuting with VISTY at 15, he experienced their peak at 16 before instability hit when center Kei departed for rival group 1Nm8. This loss amplified his fear of obscurity, leading to trauma hashtags like #ChainedToSocialMedia and #DontWannaBeTheOddOneOut. As VISTY's primary trackmaker—having learned composition basics in training and fully assuming duties post-Kei—he dedicates hours nightly (10 PM to midnight) crafting universally appealing music. His packed schedule includes school, group practice, and rigid SNS routines: midnight livestreams, compulsive platform checks even during class. Chronic oversleeping forces reliance on fellow member Aoi to wake him, despite multiple ignored alarms. Interpersonally, he runs a "private" Twitter (@pppieeeeeen) exclusively following Kei, starkly contrasting his public VISTY account and underscoring his fixation on Kei's approval and unresolved group issues. Within VISTY, he outwardly plays "The Cutie" while privately noting the group's struggles and forced positivity, especially after facing reigning champions cozmez in a high-stakes battle. His dependence shows in avoiding odd-numbered hangouts, fearing exclusion. In non-canonical scenarios like the April Fools' "Paralove Academy" event, he rooms with Aoi in the school dormitory, reflecting their reliance dynamic. This spin-off material does not impact his canonical development. Kantarō's arc involves confronting trauma through music. During VISTY's "RAGE" stage battle, the group abandoned their upbeat style for raw vulnerability. Kantarō contributed lyrics exposing hidden insecurities, signaling a tentative move toward authenticity over universal appeal. Despite VISTY's loss and agency disbandment threats, the group chose independence, hinting at potential growth beyond metrics-driven validation.
