Hizamaru is a touken danshi that was one of the prized possessions of the Minamoto clan. He earned his name by cutting a criminal from head to knee as they were testing his sharpness. He admires his older brother Higekiri and often feels depressed when his brother forgets his name, but gets over it quickly. He is shown to be proud to be a treasure of Genji Clan, along with his brother. He often gets flustered due to others' easygoingness, remarking that he's also easygoing, while he's not.
