The anime and cosplay-loving Sakura Nankyoku – known by her peers as Penguin at her old school – has just moved to a new location. After suddenly becoming student council president, she finds herself in the middle of many bizarre and ecchi situations. Panties fly, transformations are plentiful and the day is never dull in the life of Sakura, her third-grade sister Kaede, her tomboy rival Kujira, Cha Chi from China (who wants nothing more than to be Kujira's "boyfriend"), and more!
Middle school girl Momoka is dragged into joining one of the strangest associations at her school, the Survival Game Club. Its members participate in various forms of paramilitary training under the watchful eye of charming and alarming president, Miou.
Both shows are totally random, the characters are crazy, the episodes cut in short stories and they are absolutely politically incorrect. 2x2 = Shinobuden is about pervert ninjas while Sabagebu! is about schoolgirls with guns, this is the main difference. There really is no story, but you don't look this kind of show for this. You watch it because it's fun, and they both are good at this. If you laughed while watching one, you'll laugh with the other too, definitely.
