Sekirei: Pure Engagement

Minato Sahashi is extremely intelligent, yet due to his inability to cope under pressure has failed the college entrance exam twice. As a result he has been branded an idiot and loser by many. One day after talking to his yet again disappointed mother he comes into contact with a girl named Musubi who was under attack. The girl runs but takes him with her and soon finds that Minato, while unknown to him, is an Ashikabi, one of the mysterious set of masters that have the genetic trait that can become partners with some of the 108 cute girls, buxom women, and bishounen called "Sekirei". The reason for the partnership allows the Sekirei to use all their power to win in the competition held by the mysterious MBI corporation.

Seven schools are constantly 'at war' with each other, and the students within - both male and female - have become skilled fighters and constantly battle with rival schools. Their lives and fates are guided by strange jewels that contain the spirits and destinies of warriors from the Sangokushi period. One girl, Sonsaku Hakufu, has recently moved to Japan and is apparently destined to unite the schools as her counterpart united seven countries long ago. But, like all heroes, there is a darker side to her fate, and as always there is a constant struggle by those around her to break the chains of their own destinies and make their own lives.
