Budoko's owner and a junior high sophomore student. She was a timid girl who hid inside her shell and didn't have friends. Her hobby is drawing, and she often refers to people with otaku terminologies.

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!

A Japanese voice actor. She's also a certified junior and senior high school teacher.

Hirohashi was born in Niigata Prefecture, and her family's home was a Buddhist temple. Because of this, she attended Ryukoku University in Kyoto, a Buddhist university. In the middle of her first year, however, her parents told her that she could do what she liked, even if it wasn't related to Buddhism, so she sought out what she wanted to do. During her second year, she remembered a radio show she used to listen to in middle school and became interested in voice acting, so she started going to the Aoni Coaching School Osaka while attending university at the same time. The radio personality she had listened to in junior high school was a voice actor, which inspired her to become a voice actor herself.
