"Okay so is this guy a martial artist or not?"
"There is no information regarding that in his file, so I'm unsure, but if I have to guess, usually people in the assassin business would destroy all information about their pasts. So even if he is a martial artist he wouldn't be a registered one. Still, since he's someone that could kill a genius rank five martial artist, that could have entered the decade tournament, then I think he should be a martial artist. I can't imagine a normal person even with a booster could keep up with a martial artist of that level."
"Ok then do you have any information on what kind of gun is this Scorpion of his?"
"Oh, that one was easier to find info on. The Scorpion is a customized Barrett M82, the customizations made were of course to deal with Martial Artists. The Barrett M82 by itself could already kill lower-ranked Martial Artists but after its modification, it was reported that it could even harm someone on the Grandmaster rank."
