Personification of the [[tachi (weapon)|tachi]] ''Usu-midori'', treasure of the Minamoto Clan. The name used for [i][[Touken Ranbu]][/i] is one of many that the sword had obtained over the years, ''Hizamaru'' in particular referencing a practice test where the sword cut through the knees of an opponent. 

The game portrays him as the younger brother/ younger brother figure of fellow Minamoto clan sword [[higekiri_(touken_ranbu)|Higekiri]], and is highly affectionate towards him though the historical Higekiri was used to cut Usu-midori (thus earning the name ''Tomokiri'', "Friend Cutter"). This is because of the relationship between their owners; Hizamaru's owner Minamoto no Yoshitsune had his brother Yoritomo, owner of Higekiri, in high regard. He also frets about becoming "separated" from his brother again, as seen in his citadel, pre-battle quote and sword breaking dialogue.

Has [[green hair]] swept over [[hair_over_one_eye| to the right side]] and [[yellow eyes]], and wears a [[military uniform]] with [[black gloves]]. He also has rather prominent [[fangs]] when he opens his mouth.
