Mysterious boss

The most horrible a being can get.

He's a psycho killer who is the boss of a mysterious gang.

He has killed innocent people and he always seems to really enjoy it. He's always one step ahead of everyone, and he has never been caught.

No one knows anything about him, except that he's the worst scumbag ever.

He forces Ethan to kill people as many as he can, and Ethan's action was limited but was forced against his will.

He's always making up new missions that Ethan has to follow or else, Ethan is always trying to find a way to stop himself but he can't.

If you dare to cross him, you're as good as dead.
