Toukiden, the hunting game Omega Force is working on, has similar crossover items. If you pre-order Toukiden at Geo you’ll get a code redeemable for a Shop Manager Hat… which is a store on a straw hat. A bunch of retailers including Softmap, Bic Camera, Yodobashi Camera, Yamada Denki, and Gamecity will give away the Kitsune Mask with a preorder. Tsutaya and Wonder Goo have cat ears as a preorder bonus.
Loppi and HMV will give out away the Lawson uniform. Nothing says you’re ready to fight an oni like dressing as a convenience store, right? Toukiden will come out on June 27 for PSP and PlayStation Vita.
