A chipper and caring young man who often seems disconnected from the world. He doesn’t seem to have any issues integrating himself into JIGOKUGRAM, only occasionally making small comments on the lack of entertainment. However, despite being quite cooperative, he doesn’t seem entirely willing to reveal anything beyond his experience in the facility. With Iustus, he appears kind but avoidant, making it clear when he doesn’t want them to press on. Kai is rather agreeable, one of the ones more likely to go along with the other’s suggestions instead of doing things on his own. He is rarely seen alone, but some would say he is just bad at refusing and saying no.

Calm, yet enigmatic.
