Inu Yasha

Kagome Higurashi is a 15 year old schoolgirl who lives at a history-filled Japanese shrine. She is also the reincarnation of an ancient priestess named Kikyo, who guarded the sacred Shikon no Tama (Jewel of Four Souls), and who sealed away the half-demon Inuyasha who had tried to steal the jewel in order to become a full demon. Kikyo died of her wounds and had the jewel burned with her body. Kagome is one day pulled into the ancient well on her family's shrine and thrown into the past, 50 years after Kikyo's death. She befriends Kaede, the late Kikyo's sister, who realizes Kagome is Kikyo's reincarnation. They are attacked, and learn that Kagome has the Shikon no Tama, but it's actually inside her body! Kagome accidentally awakens the dog-demon Inuyasha, and frees him after the jewel has been ripped from her body. Now Inuyasha wants the jewel back, but Kagome can't let him have it. He is forced (by Kaede's magic) to wear a necklace that allows Kagome to control him with one word, "Sit!", which sends him face-first into the ground. Kagome accidentally shatters the jewel, and now she and Inuyasha have to work together to find all the pieces before they fall into the wrong hands. Only Kagome can "sense" where the shards are, and only Inuyasha is powerful enough to get them from the demons or people who have them. But can they stop fighting long enough to work together? 

Magic Knight Rayearth

Three very different (and conveniently color-coded) junior high schoolgirls, Shidou Hikaru, Ryuuzaki Umi, and Hououji Fuu, meet by chance during a school trip to Tokyo Tower. A bright light blinds them, and before they know it, they have been transported to Cephiro, a land of magic and monsters, where the power of will is the very foundation of all existence. Thankfully, they already have talents which allow them to survive in this new world, with the initial guidance of the youthful-appearing Guru Clef, who sends them on a journey to become the Magic Knights, to rescue the Princess Emeraude who summoned them in the first place, but has been ostensibly kidnapped by the Dark Priest Zagato, and, in the process, save the world of Cephiro. They are not alone, either, for they are accompanied by the bouncy, rabbit-like, uber-cute Mokona , who seems to always have they need (unless they are confronted by monsters, of course). Throughout their various adventures, the three girls soon become close friends, and really that by sticking together, they just might have the power to save this world. But not all is as it seems in the world of will.

Code Geass

The series is set in an alternate universe where three superpowers, the Holy Britannian Empire (Shinsei Buritania Teikoku?), the Chinese Federation,and the Euro Universe have divided the world between them (with the exception of an independent Australia) and maintain a tentative balance. It focuses after Japan's conquest by the Holy Britannian Empire on August 10, 2010 a.t.b., with their powerful new robot weapons, the Knightmare Frames, stripping Japan and its citizens of all rights and freedoms and renaming the country Area 11. The series' protagonist Lelouch Lamperouge is an intellectual Britannian prince who was sent as hostage, along with his sister Nunnally Lamperouge, by his father, Emperor Charles zi Britannia, after his mother, Marianne vi Britannia  , was murdered, and has vowed to destroy Britannia. Seven years later, when attacked by Britannian soldiers, Lelouch meets a woman known as C.C. who makes a contract with him. Lelouch then gains a power called Geass,also known as the Power of King,which allows him to give an order to anybody he makes visual contact with at the cost of granting C.C.'s wish. Using such power as well as his superior intelligence, Lelouch becomes the leader of the resistance movement known as the Black Knights to fulfill his two wishes: to seek revenge for his mother and to construct a world in which his beloved sister Nunnally can live happily. As the Black Knights' leader, Lelouch takes the identity of Zero, who gains popular support amongst the people.
