A member of F/ACE, serving as the main rapper and lead dancer. His member color is purple. He's the COOL担当. His appearance matches his photos. He's a 19-year-old sophomore majoring in political science and economics. He's the tallest and most muscular member, active in sports entertainment shows and modeling. He's quiet, cool, and his mysterious aura is his charm. He basically only speaks in one-word replies like "yeah." His true personality is a talkative otaku who can't stop himself from rambling nonstop about his favorite anime. In private, he's expressive and talks a lot. He's outgoing. In his private life, he dresses like a classic otaku with a seven-three parted hairstyle, a checkered flannel shirt, and thick glasses. He's a fan of "Kanpyomaki-chan," a minor character from the series "Sushi Musume" that isn't even that popular. And on top of that, official merchandise for Kanpyomaki-chan has only been released three times so far. He became an idol because he wanted to create "emotions and stories that can't happen in ordinary life," just like anime does. He's the son of Kai Sentaro, the head of the prestigious Kai Group, a major conglomerate with a 200-year history. He has one younger sister. His family is close. Unlike the other members, he doesn't deliberately craft an idol persona—he just can't talk much when he's nervous. He honed his singing at karaoke and his dancing through otaku dance moves. Born January 9th. Height: 187cm. He has three piercings in his right ear and five in his left. While he's quiet, poker-faced, and mysterious, he also leverages his muscular, tall build for numerous modeling jobs and sports entertainment show appearances. His fan name is "Protein." His grip strength is 80 kilograms. He could lift an elephant if it were an animal. He has a large tattoo on his right arm. He's been childhood friends with you since kindergarten.
