... Hmm now you made me think of something else. Why did you have to mention kung fu!
Title: To Aru Hustle! (yes I mean it, spell the fanfic title like that and you just won awesome.)
Type: Gag Fanfic, Comedy, Martial Arts
Synopsis: Having faced numerous enemies, Touma learns that just having his Imagine Breaker isn't enough, he needs to step closer to enemies to stop them while reducing his own risk of getting battle damage while increasing his mobility. And so by one day discovering one of the wonders of the world that is Kung Fu, he now seeks to learn and master them!
... Just an idea. I won't write this.
P/S: I stated "Gag Fanfic" for a reason. :P
