Hmmst. This mime reminds me of a certain green-haired, sports jersey wearing maniac. Like someone who would attack a person affiliated with some sort of "phone crew," or something. Most likely my imagination...

Anyway, conceptually this is really interesting. The always silent mime paired with a weapon often reminiscent of a form of stoicism, thus turning the mime into the strong silent type. This makes so much sense that I wonder how I haven't seen more of this idea. Good job.
