She is only one female of Jerome's assistants and only appears in the anime.
Ginga Densetsu WeedEdit
After her leader, Jerome, died from drowning in the river (and sacrificed himself to save Weed), she and her brother Ryū attacked Hōgen out of anger. However, they failed when Hōgen killed Ryū immediately, while Ryō got hurt and was nearly taken hostage. Fortunately, Weed came just in time to make Hōgen let her go, after Weed made a deal that he and Hōgen must fight in a showdown without anyone interfering.
In the end, after Hōgen was defeated, Ryō, Hanji and Heita survive in this story.
