Komachi Akimoto

Komachi Akimoto is kind and shy, and likes to read books and write. However, once she is angered enough, she will snap and release her temper. Along with her best friend, Karen Minazuki, Komachi is also a popular senior at her school. She is a volunteer at the school library, along with Karen, and often spends her time there writing stories. Her dream is to become a writer, and she exhibits particular talent in this: though he harshly criticized about the first half of it, Natts praised her first completed story upon the seventh revision, and he does not give praise lightly. Her parents own a traditional Japanese sweetshop, which has the same name as her, Komachi. Her alter ego is the Cure of Tranquility, Cure Mint.

Quiet and studious Komachi likes reading and writing. She is very kind and polite, but will be very angry and bitter if provoked. Her sister, Madoka, has also told the others in Pretty Cure that Komachi is very weak and sulky when being even slightly criticized "Komachi Gives Up on Being a Novelist!?".
