Himiko belongs to the Five Gattles, led by Jendle, later joining Abaku Onifuda in Duel Masters King MAX alongside Hyde. Her history connects deeply to Abaku and Hyde, her former classmates. A pivotal incident occurred when Hyde swapped their decks out of spite, triggering Abaku to destroy his own town in a fit of rage, shaping their complex dynamic.

Personality-wise, Himiko displays politeness toward Hyde and Jendle, but exhibits a cranky, crass-mouthed demeanor toward others. She possesses extensive knowledge of the Creature World's history.

In Duel Masters King!, she wielded a Water, Darkness, and Nature civilization deck focused on "Sutured" Dispectors. Her duel record included a victory against Cap (Episode 7) and a loss to Bolts (Episode 19). Episode 8 featured her quest for the Gaial Kaiser card alongside Joe Kirifuda and a mysterious magician.

Transitioning to Duel Masters King MAX, her deck shifted to a Nature-based strategy centered on the Demonio race. Her performance yielded two losses: against Joe Kirifuda (Episodes 2-3) and a rematch against Bolts (Episode 14). Her role in King MAX tied directly to Abaku's resurgence and his plans involving the Ourai Academy ruins.

Her name derives from Himiko, the ancient shamaness queen of Yamataikoku, though no connection exists to the card "Emperor Himiko."
