The shmup specialists only just released 2011's Akai Katana on Western shores, so it may be a while before Saidaiojou's brand of vertical bullet-hell reaches us. In the meantime, we can look ahead to the game's dress-up shtick.
Your ship's abilities and the game's difficulty depend on which outfit you choose for your supporting "elemental doll." Naturally, the skimpy bikini results in the hardest difficulty – though all the outfits look pretty skimpy, as you can see in the arcade game's trailer above.
In addition to HD visuals, a new easy mode, and a 360-specific mode, the console port will receive a new elemental doll. Presumably with new outfits. Presumably skimpy.
