Half a year has passed since Muneakira and his busty, battle-savvy friends fought valiantly in a fierce battle, and now, Muneakira is returning to Yagyuu Dojo after embarking on a journey to train his skills. But little did the man expect that Yukimura, Jubei and the rest of the gang would have turned the dojo into a maid café! What's more, past foes have been resurrected, and they have their sights set on Jubei. With new girls – and animals – to make contracts with and action at every turn, life at Yagyuu Dojo is more exciting than ever.
Minato Sahashi was living a normal life; he had just failed his college entrance exam for a second year in a row, and lived a quiet life in a single's apartment. That is, until the busty Musubi fell from the sky on top of him! She is a Sekirei, one of 108 that are destined to fight each other until only one remains; and he or she will ascend to heaven with his or her chosen one known as an Ashikabi. Minato soon finds himself in the embrace of Musubi, becoming her Ashibaki - but his life will only become more complicated. Musubi isn't the last to claim Minato as her Ashibaki, and what's worse, plenty of other Sekirei and opponents stand in his way!
On the surface the anime are very similar in one guy with limited battle capability being surrounded by more battle fit maidens. IN terms of power balance both series equally heavily prefer one character out of their group over the others but both series have similar tropes littered among the group of girls. Both series are not at all shy about showing female bosoms and while sekirei is more open about it's sexual nature in the dialogue both are about as perverted in imagery. Sekirei is basically Samurai bride without the ''samurai'' / ''artsy medieval'' feel to it.
