The game will feature animation sequences reproduced from the CD and look very well done on the PSP's small screen. And yes, just like in the anime and manga series, the game features a Costume Destruction System, so as more damage is taken, the less clothes the character will have. The game is being produced and released by Maberasu Ent. and will feature regular and limited edition versions. The Limited Edition will include a Rice with Chicken and Egg figure, which is basically Mother (Goei) and Daughter (Hakufu) in a rice bowl in nothing but their bikinis [Image Below]. I hope to provide more information on this game as it nears release, but for now pictures have been provided of screenshots along with an image of what the limited edition Figure will be.
