10. Manyuu Hikenchou

The Edo period of Japan gave rise to a clan of warriors with a very specialized, magical skill. The clan was known as the Manyuu, and the skill was the ability to administer a sword strike that could shrink the size of a woman’s breasts. This might not seem like an ability that could exert power over a land, but in Manyuu Hikenchou, large breasts denote status, wealth, fame, and influence.

Grave concern has arisen in the Manyuu clan due to the actions of their chosen successor, Chifusa. Disgusted with the breast obsessed society that the Manyuu have created and perpetuated, Chifusa has not only deserted the clan, but also stolen the sacred scroll that details their techniques to growing and severing breasts.

Fortunately, Chifusa is not completely alone. Her fellow warrior Kaede is sympathetic to her cause; a sympathy that could place her in considerable danger. Now wanted by the very clan that raised her, Chifusa must defend her life and Kaede’s while seeking to undo the damage their brethren have done to the land. Along the way, Chifusa will discover that she harbors a power that goes far beyond the scope of her training, one that could help shape and change the land that she seeks to bring equality to.

9. Freezing

Decades into the future, humanity is under siege by an alien race known as the Novas. These inhuman beings leave devastation in their wake whenever they appear, with the efforts to stave them off becoming known as Nova Clashes. Young women known as "Pandoras" and young men known as "Limiters" are implanted with stigmata to give them superhuman powers and are trained in military academies, where they must learn to work together if humanity is to have a chance of surviving.

Freezing tells the story of Kazuya Aoi as he sets out for his first day at the West Genetics military academy, right when a battle royale is being undertaken by the Pandoras. It is here that he mistakes Satellizer el Bridget—a powerful Pandora known as the "Untouchable Queen"—as his deceased sister and embraces her. Though he costs her the match, she finds that his touch doesn't drive her away and decides to take him as her Limiter. The only question is whether or not their partnership can survive the machinations of their upperclassmen and the impending battle with the Novas…

6. Ikkitousen

In Ikkitousen, the Kanto region of Japan is locked in the middle of a turf war between seven different high schools. Among the students of these schools are a select few who are in possession of sacred beads. These magatama harbor the souls of warriors who fought during the Three Kingdoms Era of Chinese history. Not only are these students blessed with abilities that draw from the souls they are tied to, but they are also blessed, or maybe cursed, with the fates of these warriors from the past.

One of these students is Hakufu Sonsaku; a young, caring, dim-witted girl who has recently transferred into Nanyo Academy and will be living with her cousin, Koukin Shuyu. Hakufu’s arrival creates an almost immediate sense of tension due to her power as a fighter and the possibility that she may be the one who carries the spirit of the Chinese warlord, Sun Ce. The most powerful fighters at Nanyo, known as “The Big Four” are shaken by her presence and determined to stop Hakufu from achieving the goal given to her by her mother: to conquer those who challenge her and unite the seven schools.
