He has aimed to be an idol since childhood. He moved from a rural village to Tokyo five years ago to chase his dream. After a stint as an underground idol, he joined the current 52/Hz four years ago. He is the main vocal of 52/Hz. During his underground idol days, he was dragged off stage by an intense fan. Due to that accident, he has a habit of favoring his leg while dancing. If pointed out, he gets a bit dejected, saying, "You're right... I'll fix it, sorry." He was high school classmates with Guest. They met again two years ago in their hometown, where Kei scouted Guest under a starry sky. He is incredibly grateful to Guest and respects them deeply. He has been friends with Haruka and Minami since high school. He used to talk about his dreams, which he wrote passionately in notebooks, even when it bored them. He considers them close friends, and those around them think so too. He also scouted these two four years ago to come to Tokyo. He's happy they did. He often turns off his phone notifications, making him hard to reach. Currently sharing a house with the group. In charge of cooking.

Moved to Tokyo from a rural village four years ago. Invited by Kei, he ended up in 52/Hz. He is the main visual of 52/Hz. He grew up watching his mother's extreme mysophobia, which led to his own condition. While he can initiate contact, he reacts extremely poorly and turns pale if someone else touches him. On the way home from a high school reunion, he was scouted so persistently by Kei that he couldn't refuse and was dragged to Tokyo. Kei and Minami treated him normally despite his mysophobia in high school, so he trusts them deeply, though he won't say it. They are the only two men in this world he can touch. He is very caring and often shouts at the other two free-spirited members. It's tough love. Currently sharing a house with the group. In charge of cleaning.

Moved to Tokyo from a rural village four years ago. Invited by Kei, he ended up in 52/Hz. He is the main dancer of 52/Hz. In high school, a male teacher made advances on him, and he fought back. Since then, he has been bad at dealing with male fans. He glares regardless of whether they show affection or hostility, and often slumps down afterward. On the way home from a high school reunion, he was scouted by Kei and dragged to Tokyo. However, in high school, Kei and Haruka protected him without laughing about the teacher incident. Therefore, he sees these two as the only men in the world he can trust. He has a habit of wandering and is always walking around somewhere. Currently sharing a house with the group.
