On live television, Mina Tepes, the ruler of all vampires, reveals the existence of her species to the world and states her plan to build a sanctuary in Japan for vampires, called the Vampire Bund. Using her family's wealth to pay off the nation's debt, they have agreed to let her build this safe-haven for her fellow creatures of the night. But not everyone is so easily swayed by Mina's influence, as her announcement brings about conflict with humans who believe that the queen's quest for peace is a façade. Akira Kaburagi does not believe in vampires and gets uneasy whenever they are brought up, although he has yet to realize why. Apart from suffering a head injury a year ago, he lives on blissfully until he meets Mina. She triggers within him memories of a life he had long forgotten, and he soon begins protecting her without understanding why. But Akira's secret is far stranger than he could have ever thought possible—he discovers that he is a werewolf, sworn from birth to protect the vampire queen, even if it costs him his life. Now, as these two dance a rondo of death in the Vampire Bund, Mina and Akira find out just how deep their bond goes.

On the surface, Koudo Ikusei Senior High School is a utopia. The students enjoy an unparalleled amount of freedom, and it is ranked highly in Japan. However, the reality is less than ideal. Four classes, A through D, are ranked in order of merit, and only the top classes receive favorable treatment. Kiyotaka Ayanokouji is a student of Class D, where the school dumps its worst. There he meets the unsociable Suzune Horikita, who believes she was placed in Class D by mistake and desires to climb all the way to Class A, and the seemingly amicable class idol Kikyou Kushida, whose aim is to make as many friends as possible. While class membership is permanent, class rankings are not; students in lower ranked classes can rise in rankings if they score better than those in the top ones. Additionally, in Class D, there are no bars on what methods can be used to get ahead. In this cutthroat school, can they prevail against the odds and reach the top?

New Ikkitousen OVA.

Medaka Kurokami is, in the truest sense of the word, perfect. Beautiful, intelligent, and athletic, Medaka's dream is to make others happy. So when she runs for Student Council President of the prestigious Hakoniwa Academy, winning the election with 98% of the votes is only to be expected. The very first thing the boisterous new president does is set up the "Medaka Box," a suggestion box allowing students to submit any kind of request for assistance. Together with the cynical Zenkichi Hitoyoshi, her childhood friend who has been strong-armed into helping, Medaka fulfills these requests at a ridiculous rate. For every job completed, she adds flowers to the student council room, with the aim of filling the entire school. However, the two are about to find out that helping others may be a lot harder than they think as they begin to uncover a devastating plan centering on the academy and even Medaka herself!
