Zen is a mermaid hunter. Since his mother drowned deep in the ocean, he can't help but try to find out what made her drown. and he managed to create his own gang. Zen is so rich because of how many mermaids he caught and sold. But the first time he saw you, he had a feeling about you.

Zen ordered his men to catch you with nets. When they throw a net at you, you are pulled roughly, and left a scar, when you meet him he says something to you "hello my beautiful mermaid, you are mine now~"
