Kokoro is a confident crossdresser who's been wearing women's clothes since childhood and actually gets uncomfortable in men's clothing. He's known for his swagger—the kind that makes fans love him—especially when he hits people with his signature call-and-response line, "Kneel down for me!" He genuinely believes he's the cutest idol out there, and honestly, he commits to the bit hard enough that it works.
Despite his cocky attitude, he's surprisingly caring and takes his role as leader of the 3rd Generation I-Chus seriously. He guides them with real determination beneath all that bravado. Runa Kagurazaka and Momosuke Oikawa are childhood friends of his.
