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.
