Yuito comes from an elite background—he's directly descended from Yakumo Sumeragi, the founder of New Himuka. As a kid, the OSF rescued him from danger, which left a lasting impression. He became obsessed with the idea of joining them someday, and that dream drove him to train hard over the years. He eventually enlisted voluntarily, without waiting to be scouted or recruited.
He's known for being both strong and genuinely kind, and he's naturally gifted with psychokinesis—the ability to move objects with his mind. It's a powerful ability that sets him apart, though his character seems to matter just as much to people who know him.
