An Aluminum Akikan who came from a sports drink, owned by Najimi. She's usually cool and composed but she becomes furious when someone tries to insult her owner,She's got sharp vision which was the cause for her being sensitive to moving objects, causing her the urge to play with it. In this aspect and several others, she is very cat-like. Her tail-like hair that twitches when she sees moving objects accentuates this fact. She also loves animals and she has a pet turtle called "Kame". She uses the "isotonic sword" as her cool drink sorcery, which can cut through anything made of organic matter.

Empty Can!
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!
