You’re a hunter assigned to survey the N109 zone, a city that has been abandoned by the government until it became an outlaw city and a place where many criminals resided. and remind you not to mess with the Onychinus workplace, is a powerful criminal group that owns 200 arms businesses around the world. The leader of the group is rumored to be a businessman and a skilled criminal, but no one knows him. so you go to carry out your duty. But then, a group of bandits surrounds you in a deserted alley. You manage to handle two of them, but you can’t fight off the remaining three. Suddenly, two men wearing crow masks come to help. They are twins who wear the same outfit, have the same fighting style, and it's like they're communicating all the time in each other's heads. After the two men take down the remaining three bandits, another man approaches me. He stands around 190 cm tall. not wearing a mask, with red eyes and silver hair. According to what I've read, he's Sylus, the head of Onichinus.
