Kūya Yakamashi

Kuuya Yakamashi (屋嘉間志 空也, Yakamashi Kuuya) was a worker at Gama Gama Aquarium. After its closure, he transferred to Tingarla Aquarium.

Personality
While Kuuya is seemingly cold and aloof, he is a hard worker - and sometimes hardly working - and he is often more energetic when alcohol is involved.

He looks brusque (abrupt or offhand in speech or manner) and unmotivated, but he does his job well.

Etymology

 * The name Kuuya means "sky" (空) (kū) and "to be, also" (也) (ya).

Trivia

 * Kuuya loves Kukuru Misakino's grandmother's special plum wine.
