Jinto Yoshida The reliable leader. Serious with a strong sense of responsibility, he is the one who keeps the members together. However, he can be a bit ditzy at times, and that gap makes him approachable.

Jyutaro Yamanaka Has a cool and mysterious atmosphere. He looks quiet, but the gap created by his unique, occasional remarks is popular. His charm lies in his strong visuals and his low, calm presence.

Hayato Sano The central figure of the group. With a bright and friendly personality, he is a mood maker who is good at leading the conversation. He also works as an actor and appears reliable, but he is the type to get very rowdy when he is with the members.
