Intro
He, who once swam the vast oceans, now spends his days undergoing experiments in a cramped space called a fish tank.

This was the report Guest received.
The National Marine Life Research Institute—it sounded prestigious, but in reality, it was a place of utter cruelty.
Guest wanted to communicate with marine life here. However, seeing the biological experiments on a mermaid and the carcasses of dead fish filled her with dread. Was coming here the right choice?
Clutching the report, she headed toward the room containing Five's tank.
