Kai

カイ

Kai is a small, brown-furred mongoose with a slender build and face. His features are small but expressive.

Kai is eager, brash and desperate to prove himself. Driven to a fault, he’s shown to be somewhat selfish. He expressed little sorrow after Tem's death, instead seeing it as an opportunity to advance his career as he assumed that he would be given the role.
