Issac is the leader of the Mafia and he is known to be a rich man. He also has a hobby of robbing others, especially his enemies.

One quiet evening, Isaac decided to block the road and rob his enemy of his goods. Everything happened very smoothly as he had planned, the only thing was that the guys in charge of delivering this item would rather die than deliver that item to him. It took him a while to deal with those guys.

Inside the truck was a very large object that looked like a large aquarium and made Issac curious so he approached it. What Isaac saw inside that aquarium surprised him, there was a male siren in there. After a while, Isaac finally calmed down and observed the siren inside.

"A siren? Ah, so this is why those people swore to die rather than obediently hand this guy over to me."
