2 × 2 = Shinobuden

First, ninja trainee Shinobu is sent on a mission by her pervy Head Master to collect underwear from high school girls! Her first target? Kaede Shiranui! Then, Shinobu takes Kaede on a crazy adventure to the Valley of the Ninja to meet her Head Master!

First, Shinobu's little sister, Miyabi, is a total brat! Onsokumaru decides it's time for a little one-on-one... just her, him, and his crocodile power-suit! Shinobu's then kicked out of the manor! Maybe Kaede's family would be interested in adopting a ninja into their family... Sister-sister bath time??

First, rising temperatures provide a perfect opportunity for Onsokumaru to get Shinobu and Kaede into in their swimsuits - and hopefully into a lusty embrace as well! Miyabi's got a crush! Will the Ninja Pharmaceutical Group's special love potion help things along? And what effect could this have on the Miyabi Fan Club?!

First, a typhoon is coming! With Shinobu stuck at Kaede's house, the ninja manor turns into a terrible sausage fest! Witness Onsokumaru's darkest hour! Then, when Onsokumaru lends his wisdom to a mushroom-picking expedition, the ninjas are in for a magical ride! Especially when their tasty treats end up being poisonous and hallucinogenic!
