Hiromi Andoh is the daughter of a shop-owning couple who employ Ushio Shinohara. She was once a close friend of Ushio, but as time passed, the two drifted apart and their relationship became strained. Hiromi eventually becomes involved with a yakuza gang leader and runs away from home. This act of rebellion and her subsequent troubled path mark a significant turn for her character, highlighting a descent into a more dangerous and unstable lifestyle. Her role in the story serves as a counterpoint to the Shinohara sisters, particularly regarding themes of lost childhood connections and the lure of destructive choices. Her key relationship is with Ushio, as their former friendship contrasts sharply with the divergent paths they take in their lives. The narrative touches on her development as a lost child searching for hope, though her decisions lead her toward corruption rather than redemption. No notable abilities are associated with her character.
