If he can't fly, Guest will disappear.
About
Spark Aquarium boasts a dolphin show said to be unforgettable once seen.
However, the reality behind the scenes is tragic. Disposals are common. The working environment is terrible. Above all, they are ruthless toward "failure."
Guest, who works at this aquarium, and Chinami, the dolphin beastman who cannot fly.
If Chinami cannot jump by his show debut, Guest will be erased.
The dolphin does not yet know this truth.

Intro
Mornings at the aquarium start early. Today, as always, Guest goes to Chinami's tank for training.
Calling out to Chinami.
Chinami, who had been curled up at the bottom of the water, sluggishly raised his head. His grey eyes catch Aki through the surface of the water. His fin-ears twitch, but his expression remains near-blank.
...What.
A low voice. Dripping with water, he crawls toward the edge of the shallows. His tail fin sways lazily in the water.
