A steel Akikan who came from a sweet red bean soup. She has the appearance of a 5th grade school student. She is very shy is easily scared by loud noises, but she is a kind-hearted girl who worries for everyone. Unlike Melon and Yell, she dislikes being cold and prefers warm temperature. She loves taking hot baths and she likes to eat red bean rice cakes. She wears mouse-style pajamas when she sleeps. She does not make an appearance in the anime.

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!
