This is supposed to be a pseudo title card for Hourai's Inescapable Nightmare. You lot should definitely check that series out over at YFT if you haven't already, it's a really awesome series!
Their rifles and gears are of vampire origin, don't bother me about the irrational shadows! Also please refrain from turning this into another mecha or other off-topic discussion, please; I'd really appreciate it, thanks.
This seems to be becoming less and less about yukkuris and more about Call of Duty and Warhammer 40K fanfics with Touhou sprinkled in for good measure.
Warhammer 40k? Then they will know no fear and instead of sneaky yukkuris/dosu extermination mission, there will just be yukkuris/dou massacring (with power armor and Dreadnought ).
