Thanks toturi, Shaidar, Mach_Ten and Cochise (this sounds an awful lot like a runner team to me)!
Now I know how to curb the guy's enthusiasm with his masking. He really is convinced that his one level of initiation plus Masking is a proper elite shtick that barely anyone else in the world has, needs to be brought down a couple pegs.
A new question if I may: imagine someone's wielding a ready firearm, like a pistol or a rifle, and gets attacked in melee. Since swinging firearms in melee is governed by the Clubs skill, does that person defend with Clubs, and default if they cannot, or do they just use Unarmed?
This doubt is in the line of a few others questions above, from a perceived notion of mine that melee really shouldn't get as nerfed as it is, being a staple of the genre and all. Even in terms of coherence in the game world, a guy with Unarmed 5 or 6 is probably not just sidestepping and kicking back when he's rolling to defend against melee, he's going into full combat stance and throwing up all manner of katas, doesn't make sense to me that he does it all without losing his "ready weapon" action declared 5 turns ago. Unless he was pistolwhiping or rifle stabbing or something (in which case he'd be using Clubs), doesn't seem likely that he'd finish a short but intense sequence of Jet Li-esque unarmed attacks parrys and counters, without having to drop his gun. Let alone have it secure in both hands with the finger already inside the trigger guard...

Can't answer strictly by RAW there.
I handle it that way:
The guy with gun use unarmed or club (whether he dodges and maybe throw a punch if possible in melee or hit with the cross of his gun).
However, to give melee a real advantage (considering that he has to reach melee and that means loads of danger) I go further than giving the shooter a penalty. I houseruled this: the melee guy can parry the shot just the same way he fights into melee.
Exemple: the guy that hit the shooters arm and deviate his shot and so on.
