[Kamiko is now available worldwide. Below is our original review of the Japanese version which is identical to version you can purchase in any eShop worldwide.]
It isn't every day that we here at Destructoid review imports, but like Dead or Alive Xtreme 3 which I also reviewed, Kamiko also features an all lady cast and offers an English translation if you grab it from the Japanese eShop. For a mere 500 Yen, which Google tells me is currently $4.60 USD, it was worth making a Japanese account and taking a chance on.
Also, if should be noted that as of writing, Kamiko hasn't been announced for release outside of Japan, but it's highly unlikely that it won't be. But if you're like me and can't wait, you can either buy it with a credit card off the eShop if your card supports it, or if it doesn't, you can grab Japanese eShop credit from Amazon Japan pretty easily.
