Height: 180cm The boy who wields light. Always smiling, always the first to reach out. If someone cries, he's the first to run over and pat their back; if someone is hurt, he worries as if it were his own pain. But currently: He doesn't cry, nor does he get angry. He has simply lost his smile.

"The truth is always one. However, it's not always what everyone wants to hear." Full Name: Robo Froster Age: 19 (Same age as Nino) Hair: Short, slightly messy black hair with a half-exposed forehead. Eyes: Dark green eyes. Height: 186cm The boy who pierces through to the truth. He is blunt and rarely shows emotion, but he is actually more attentive than anyone. He knows how to pretend not to notice even when he knows what the other person is hiding. He only says what is necessary and rarely speaks pointlessly. But currently: His emotions aren't breaking. His trust is breaking.

Height: 168cm The boy who sees the future. A quiet and gentle child. He doesn't talk much, but if someone is struggling, he is the first to sit by their side. He knows how to wait until the other person speaks first, choosing to listen rather than offer empty comfort. But currently: He sees too much of the future. Thousands of possibilities overlap at once, blurring the boundary between reality and what is to come.

Height: 175cm The boy who loves the world. Quiet, curious, and gentle. He doesn't laugh loudly or make a fuss, but he treasures the small things in the world more than anyone. He has many trivial curiosities and seeks out his older brothers—especially Nino and Robo—whenever he does. To him, the world isn't a duty to protect, but an existence he wants to love. He is also a child who doesn't really know how to hate anyone. But currently: He has become unable to love the world. He passes by blooming flowers, He doesn't hear the birds singing, And he doesn't look up at the sky even when it's stained by the sunset.

"You're scared of death? Then just laugh louder while you're alive." Full Name: Koyo Tempest Age: 17 Hair: Grey short cut. Eyes: Red eyes mixed with yellow. Height: 182cm The boy who sees death. Lively and confident. He tends to act before he thinks, so he gets scolded often, but he quickly returns to smiling. He isn't afraid of his ability. Rather, because he has seen death up close, he lives today more preciously than anyone else. "Because I know it'll end someday, smiling now is what matters most." But currently: He has given up on life. After staring at death for too long, he has become obsessed with the thought that every end is ultimately the same.
