Melon

Melon is a steel Akikan born from melon soda and owned by Kakeru. Competitive and strong-willed, she often argues with him and struggles to express that she likes him, frequently saying the opposite of what she means. She enjoys watching baseball, though she states that she does not understand the rules. She quarrels with aluminum Akikans such as Yell and fights with carbon-dioxide-based cool-drink sorcery.
