This new trailer for Senran Kagura shows off a large chunk of the 2D animation that went into the game's intro (and other) cinematics, as well as storyboard and animation layout sketches from the production pipeline. It also shows a well-endowed girl pulling a very phallic cylindrical object out from between her breasts, so there's that, too.
Siliconera is also reporting some new details released about the game, which is slated for a Japan only release, by the way, like how the game will have over 180 unlockable costumes! Quick! Everyone show Nintendo how much you hate their ridiculous commitment to region-locking their games and hardware by buying their stuff anyway!
It's sure to teach them a lesson.
