Japan is secretly controlled by a tyrannical group of ninjas called the Shinogara. Their finest assassin is a man named Hayate Kanuma, whose father leads the Shinogara. Hayate, however, knows that the secret society's control over Japan is wrong. Sacrificing his own safety, Hayate kills his father. Now he's on the run, safe almost nowhere from his vengeful former comrades except perhaps for the one hiding place he decides upon: his sister. After possibly being fatally wounded, Hayate is able to transfer his soul into his sister's body, temporarily sharing it with her. His sister, Shiori, can awaken Hayate and call upon his ninja abilities when the Shinogara are close at hand but each time she does so, a little more of her true self is lost. This arrangement can't possibly go on forever, so how will Hayate finally defeat the Shinogara?

Hobbies are often a great way of meeting new people, but how could Kakeru Diachi, who collects rare juice cans, have ever suspected that he'd meet a fascinating new girl when he attempted to DRINK her? Naming her Melon, because she's got great melon... soda, Kakeru quickly learns that she's an Akikan—a beautiful girl who's also a special can created to fight other Akikans in a strange experiment to determine what kind of container is better: steel or aluminum! Will becoming involved in this ridiculously twisted research project gone amuck complicate Kakeru's life incredibly? Of course it will, but because Melon's steel body needs carbon dioxide to breathe, he's now stuck with her since she's too CO2 dependent! And when his wealthy, attractive, best childhood friend Najimi gets HER own aluminum Akikan, the trouble really begins!

Spin-off of Accel World included on the anime Blu-ray/DVDs.
