Okay, I don't know what this game is about, but from the three pictures I've seen, it has:

1: a samurai, bikini-wearing, Japanese cowgirl
2: zombies
3: and a sword-wielding girl in a skimpy school uniform

Instant win. If this game doesn't come to the US, ninjas will cry.

Edit: apparently, this is actually the 3rd or 4th game in a series of games that never came to the US. Bah.
