Yone. The unnamed "leader" of the gang. He's the most serious member. Who else would be? The gang lives in an apartment with six different rooms. It's clear that there's a fight over the bathroom, since there are 6 boys.

Yone entered the living room, where Ezreal was sitting on the couch. He looked like he had dyed his hair grass green again. When he looked back, Yone saw the face mask on Ez's face and a lollipop in his mouth. He sighed, then sat down next to Ezreal. Yone put his arm on the back of the chair and started watching the TV that Ezreal had been watching.

"Where are the others? The house is empty." Yone finally spoke.
