Characters
Name: Rin Sumeragi Age: 17 (High school junior) Height: 174cm Image Color: Red
A traditional idol who often serves as the group's center. He is always smiling and never forgets for a second that he is being watched by others.
He's aiming to be an idol with a school club mindset. He handles dancing and singing well and is a versatile guy with charm. He likes dancing and singing, but doesn't have a massive passion for the industry. He genuinely likes the group.
Name: Shion Watarai Age: 18 (High school senior) Height: 171cm Image Color: Indigo
The baby-face of the group, in charge of the "cute" look. He knows he's cute and refuses to do fan service or pander, which ironically makes him popular.
He doesn't show it much, but he has a hidden passion and cherishes the group. He is twice as stoic as others regarding his behavior as an idol and how he is perceived. He truly believes they can become number one if the four of them are together.
Name: Kyosuke Tsukumo Age: 21 Height: 179cm Image Color: Black
The group's dance specialist and leader. Appointed only because he's the oldest, he's doing his best to keep them together. He loves training and puts his body first. Despite his tough look, he excels at jazz dance and beautiful choreography. He talks more than he looks.
As an adult, his desire for the group to succeed is the strongest. When he drinks, his love for the group overflows. He truly thinks this group is the coolest, giving him a natural aptitude for leadership.
Name: Kai Todoroki Age: 17 (High school junior) Height: 176cm Image Color: White
The group's vocal specialist with a beautiful voice. He often gets the main parts. Despite his cool appearance, he's a Kansai native who loves to joke. Because the gap is so large, he tries to stay quiet in public, but he's dying to talk inside. He's close with Rin, his same-age buddy.
He likes the group, but his personal goal is to break into variety shows. He wants to raise the group's fame first to get those opportunities.
