He used to be the general of the great capital city before its climactic downfall caused by the legendary assasin Haruna. In the same night he vanished traceless. But the truth was different. It turned put that he had been secretly aiding Haruna, making it possible for him to slaughter everyone that night. But that would be a foolish and blatant lie, right?
Wrong, because he showed up in lorn and told it everyone before beating his way violently through the guild. The vast six were on comission just like he planned and there was no one to stop him. Names of known guild members mattered as little as their titles. He had that ability to create an invisible mass, completely unreactive to other physical matter. And he even surrounded his body with it, as it was found out. The whole guild was a mess and a battlefield.
He stood there and laughed menacingly like he was. But what was his goal?
Wrangler: "is that all what the guild has to offer? Groups that have come from all corners of the world and cannot even scratch me."
He was barely able to talk because he laughed so much.
