Since you like weapons I suggest you go train martial arts and buff up. Lots of girls whom I know find guys who train martial arts manly and tough, and they would then look as your weapons as awesome. On the other hand if you just collect and do not train they might see you as a potential violent rapist or something. Illogical, but some girls seem to think that way.

You can go to those anime cosplay expos, should be right up your alley.

Please don't end up like this:
