A steel Akikan who came from a melon soda, owned by Kakeru.  She&#039;s competitive and strong-willed, which was the reason why she was always having a fight with Kakeru.  Although she likes her owner she cannot express her feelings well, which ends up telling opposite of what she wants to say.  She likes watching baseball matches, even with midnight telecasts, though she has stated she has no clue on how the game is played.  She basically hates Aluminum Akikans and is always having small quarrels with Yell.  She mostly uses carbon dioxide based cool drink sorcery in battle.

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&mdash;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!
