My SF Gun Romance

You know how it is. One day you're playing your favorite game, crafting a new gun for your Lancer class battle armor, then the next you're "level 1" in the fantasy medieval world you've been summoned to.

NOT!!!

Is this reincarnation? Did I kick some special kid's favorite dog and got reincarnated into a world without even gunpowder? I need explosions and fire and BAM and RATATAT and WHOMP. Oh, the whomp from a good grenade. Can anything beat that?

Yes! The quadruple whomp whomp from a grenade launcher loaded with MIRV rounds.

What is this swords and bows and staffs crap? I mean-

Wait a minute. What about toilet paper? Hey! Anyone? You have toilet paper here right?
