Yaeko (Yakko) Mitamura: 18 year old at the beginning of the story, Yakko works at her father's okonomiyaki restaurant "Mambo" in Osaka as well as attending evening classes at the university. Yakko is romantic and a little naive, and she is flattered by the attention paid to her by one of the regular customers of her father's restaurant, handsome and long-haired Satomi Okawa. One day she casually meets two people that will change her life: Go Kato and his little brother Hashizo. Yakko soon discovers that Go and Satomi are friends and both members of an emerging rock band, "Bee Hive". She is attracted to them both, but soon she will have to make a choice between them.
