Himiko Kudou

Himiko once worked with Ban Mido as a thief in the pre-GetBackers days, along with her older brother Yamato Kudou. When Yamato was 28 years old, he was alone with Ban in their house so that they might face his "Voodoo Child mirror" (Himiko was sent out to buy a cake.) As a Voodoo Child, if one of two halves dies, both perish. Ban realises this too late when his "Snake Bite" killed Yamato's other half. When Himiko came back with the cake, she saw Ban's hand covered with Yamato's blood. Since that day, she has held a grudge against Ban. Occasionally an enemy, but more frequently an ally, Himiko has mixed feelings for Ban, whom she sees is a good person, but cannot reconcile this with her brother's killer. On Ban's part, he treats Himiko more like a little sister (his nicknames for her are "washing board" and "landing strip girl", referring to her bust despite her having a fairly impressive one).
