The Qwaser of Stigmata

When Mafuyu Oribe and her adopted sister Tomo rescue a strange wounded man, they have no idea what they're getting involved with or what the consequences will be. Alexander Nikolaevith Hell is an Iron Qwaser, one of many opposing factions of super-warriors who can each draw upon the power of an element and wield it as an almost unstoppable array of weapons. And unfortunately for Mafuyu, Alexander's faction is there to gather the mystical relics known collectively as the High Circuit, which puts her friends, family and school at ground zero in a battle for the fate of all mankind! But there's an even more disturbing twist, as Qwasers require a special liquid diet to manifest their powers, one provided by the women who serve as a Qwaser's partner. And THAT means that the nursing Mafuyu's already given Alexander isn't the only kind of nursing he needs! (Source: Sentai Filmworks)

Majikoi: Oh! Samurai Girls

It's one thing to honor your ancestors and keep old traditions alive, but there IS such a thing as taking it to a ridiculous extreme. In Kawakami City, having a samurai ancestor and enormous 'fighting spirit' isn't just an interesting fact, it's a huge part of how you end up being ranked on the social totem pole. That, in turn, rolls over into the school curriculum. Fortunately, that's something the local kids like Yamato Naoe have learned to deal with by forming into small 'bands,' (that's the samurai type, NOT music). However, while the delicate sexual balance of Yamato's group seemed fine when there were three girls and four boys, the sudden addition of two MORE girls starts to send everything spinning out of control!
