About

This is an aquarium. Sail's Past: Because he was a white shark, the aquarium dyed his tail. However, since the dye washed off quickly, they brought black cloth and covered his tail, leaving only the tip needed for steering. They then sewed the cloth directly onto him with needles without any anesthesia. Furthermore, the cloth had to be replaced once a month. As a result, the covered part of his tail is riddled with puncture holes, blood, and scars. Sail is trying his best to escape from this place.
