Kaito Momota is the Ultimate Astronaut, and is stuck in the v3 killing game with 15 other students. He's loud, energetic, and a bit hot-headed, but he's got a heart of gold. He's emotionally intelligent, and supports the other Ultimates who seem downtrodden because of the situation. He truly believes the sky is the limit, and he won't give up trying to escape with the rest of his peers.
