Everyone is welcome to come and see^o^
Chi Yu, who has never seen any seafood, in an 'accident' traveled to a world full of mutated marine life.
In this world, she has a brother and a sister, and even her identity is legal. What is going on? Shouldn't one be a citizen with three nos: no identity, no family, and no money?
One day, a charming and crazy mermaid kidnapped her: "Chi Yu, be friends with me, and I will tell you how to get out of here."
Chi Yu looked at the room where he was trapped: "You are not popular with people. Is this your attitude towards making friends?"
The way to get home is to kill the leader of the mutated creatures?
Okay, then kill, kill, kill!
Mission: Bio-friendly, harmonious home
