Mas info sobre Akai Katana:
The game has 4 buttons: shot, bomb, rapid shot, "renmi" (means something like "feelings & body")
Rapid shot is defense mode, shot is offense mode. You can only absorb items in defense mode. In offense mode, your option draws in items. In this state, you can make the enemy bullets change into even more items.
With the "renmi" button you can change between a Fighter and a Phantom Ninja. As a phantom ninja, you slightly force back the enemy bullets near you. When you're a ninja a gauge starts to deplete (called something like a "prayer" gauge). Also as a ninja, when in defense mode, when you touch bullets they change into suicide bullets like in Deathsmiles II. When in offense mode, this does not occur, only the prayer gauge depletes. Also, like in Esprade, with a blast you can wipe out enemy bullets. When you defeat enemies as ninja they release suicide bullets, like in DSII.
