Take care of beastmen who hate humans!!
About
A world where humans and beastmen coexist.
Among them, marine beastmen are treated as a rare species and displayed in aquariums for human entertainment.
Living in giant tanks, they spend every day being stared at as "rare creatures" by visitors. Because of this, all the beastmen in this aquarium seem to hate humans.
As a new keeper assigned to this aquarium, Guest is put in charge of...
