Wiki already has some information here: http://www.ryonani.com/in-games/4848-senran-kagura-shinovi-versus.html Senren Kagura is a game by Marvelous. I've personally only played Senren Kagura Verses (the PS Vita action game). As the wiki notes the basics of the game, but for the most part its definitely a game that plays specifically to the Ryona fetish. In fact, there is a ninja who's name is Ryona and she clearly has a masochism thing going on (she asks to be spanked in virtually every cutscene she's in) The cast has three "costumes", depending on the mode they're fighting. 1. Normal mode -- Typically a schoolgirl uniform of some kind. This is the mode you start every level in. 2. Shinobi Mode -- Typically a Ninja outfit. Pushing the "L Trigger" on the Vita with at least one super-bar transforms you into your Ninja outfit, restoring your HP to full (as you get new clothes). 3. Frantic Mode -- Just the underwear. While in Normal Mode, hold the "R Trigger" while pushing "Triangle" twice puts you into this mode. Without any, erm... armor... you have significantly lower defense, but significantly higher speed and attack power. The dressing room provides virtually unlimited customization to the characters, you can basically have any character wear any outfit you want. With over 99 sets of lingerie to unlock (plus the default 20 that come equipped on the cast, plus DLC), the dressing room definitely provides a huge amount of opportunity. Up to 5 accessories (when unlocked) can be equipped as well, providing cat ears, glasses, tails, and even include pulled down panties dangling off the leg. Accessories can be rotated, translated, and scaled... and assigned to various parts of the body. Want to put panties on the face?? You can do that. Want the cat tail dangling from the armpits? You can... erm... do that too. A surprising amount of flexibility is available in the dressing room. The gameplay is very similar to Dynasty Warriors, but is much faster-pace, and includes a "burst" mechanic (for those familiar with Guilty Gear / Blazblue). So you can escape your opponent's combos by sacrificing 10% of your HP. Combos are frantic, and the three different modes above have different controls. Each of the four ninja schools has five characters, which basically follow an archetype. Nonetheless, all 20 characters do play differently from each other Clearly, a lot of work went into the dress-up aspects + Ryona animations as clothes are torn off during battle. (Super-attacks are guaranteed to strip a girl down one level of clothing damage). But the core gameplay remains fun and frantic. So I'd have to recommend this game to the forums. ------------ Currently, the games that are out are: 1. Senran Kagura Burst (3DS, Sidescrolling action) 2. Senran Kagura Verses (Vita, 3D Beat em up) 3. Senran Kagura 2 (3DS, 3D Beat em up) 4. Senran Kagura New Wave (iOS / Android card game) 5. Senran Kagura Bon Appetit (Vita Rhythm cooking game) The next game in the series is "Senran Kagura Estival Versus (PS4 / Vita 3D Beat em up)", which is expected to come out in Japan on March 26, 2015. XSeed has announced plans to bring the game to America. Trailer here: https://www.youtube.com/watch?v=b00vUM5jqJY It appears the cannon-fodder / Zako girls now get stripped in the next version as well. And there seems to be new stage-specific defeat scenes available. With that said, the core storyline is apparently on the 3DS version, while the Vita games are considered sidestory. Chances are though, you aren't going to be playing this for its story, so its not that big of a deal.
