Kuuya Yakamashi 屋嘉間志空也

A staff member at Gama Gama Aquarium. He speaks frankly, and looks lazy, but is very serious at his job. He is not good at talking to girls in his age group, and often avoids making eye contact with them. With the aquarium as short handed as it is, he runs long shifts that tire him out. He is quite fond of the umeshu that Kukuru's grandmother makes.
