Moroha is the daughter of Inuyasha and Kagome Higurashi, a quarter-demon bounty hunter who slays demons and sells their parts to other demon slayers, presumably so they can make weapons and armor out of them. She wields the yōkai sword Kurikaramaru and is known as "Moroha the Monster Killer". Tragically, Moroha knows very little of her parents as she has lived alone most of her life. She likely knows her cousin Setsuna through her business dealings with demon slayers.
