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!

In a world of magic and monsters, Krylancelo Finrandi and his foster sister Azalie Cait-Sith were once promising students of sorcery, prodigies at the famous Tower of Fangs. But an experiment gone horribly wrong warps Azalie's appearance, trapping her in the form of a dragon. Elders at the Tower—more interested in preserving their reputation rather than their students' lives—drive off the transformed Azalie and cover up the incident. Outraged, Krylancelo strikes out on his own, taking the new name of "Orphen" and vowing to return Azalie to her normal state. Five years later, Orphen's quest has stalled. A chance encounter brings him face to face with Azalie again, but he still has no way to restore her body. And with a hostile group of sorcerers hunting her down, he may be running out of time. The past and present collide as Orphen tries to find how to save Azalie from their former teachers and friends.
