Quanxi

Quanxi is calm and stoic, having no shame in discussing business while she's in bed with her harem of fiends, showing little emotion even as her girlfriends fawn over her. Part of her indifference seems to stem from a belief that "ignorance is bliss" as she tends to be put off things she used to enjoy by learning more about them. However, she does deeply care for her fiends, making her one request for a reward be that they are given human rights and a basic education, and not attacking them even after they have been turned into dolls at the cost of her own safety. Quanxi is ruthlessly pragmatic in combat, preferring to throw her enemies outside of the battlefield in order to efficiently cut down their numbers and remove distractions. Similarly, after being cast into Hell, she instantly requested a ceasefire in hostilities so as to determine their situation. This alliance continued until the moment the threat was contained, at which point she immediately attacked once again. Though her attacks are swift and brutal, she can at times choose to leave those other than her target alive, as highlighted when she knocked Aki and the Angel Devil unconscious and offered to spare Power's life. At other times she did slice through some Devil Hunters, hired to protect Denji, that weren’t her target. Quanxi seems to have a past amongst the bureau, being referred to by Santa Claus as "The First Devil Hunter". This suggestion is furthered by her conversation with Kishibe, hinting at a past friendship between the two. It was revealed in Volume 8's omake and Chainsaw Man: Buddy Stories that Quanxi and Kishibe were formerly partners during their career as Public Safety Devil Hunters. Despite fighting him due to recent events, she still considers Kishibe an "old friend" and takes his advice, as evident when she refuses to hurt Denji's body during Asa Mitaka's raid of the Tokyo Devil Detention Center because Kishibe wanted to protect him.

Human Form
Quanxi is a tall woman with cream colored hair tied back into a ponytail. She wears an eye patch over her right eye, has a brown left eye, and possesses an athletic build with rather wide hips. In her debut arc, she wears a black tank top tucked into waist-high pants with a large belt during her mission to retrieve Denji's heart. When in combat, Quanxi dons a set of sheathes on her back, holding up to three swords which resemble Dao. In Part 2, Quanxi currently wears the standard Public Safety Devil Hunter suit and tie, which she wore during her past stint in Public Safety and also during her time as one of Makima's brainwashed servants. Her eyepatch sports a different design, now appearing to be made of frilled lace instead of leather. She also wears a matching, black lace choker.

Physical Prowess
* Enhanced Strength: Quanxi possesses a level of strength having been described by Hirofumi Yoshida as being beyond what is humanly capable. When wielding swords, she can cut through dozens of humans and dolls without slowing down and only stopped once her weapons were destroyed by the force of her own attacks. Even a blocked strike was enough to knock out both Aki and Angel. Her strength is remarkable enough that even when in her human form, she was capable of dismembering three Weapon Hybrids, even when one was transformed. *Enhanced Speed: Even in her human form, Quanxi possesses superhuman speed. She could disappear from the sights of five Devil Hunters by blitzing past them while cutting through an army of dolls created by the Doll Devil, before the original five Devil Hunters realized they had already been killed. More remarkably, she was capable of beheading three Hybrids before any of them could properly react, all while in her human form. *Enhanced Reflexes: Quanxi has superhuman reflexes, her time perception can keep up with her own superhuman speed. She can also dodge attacks rapidly and even stop a moving knife with her fingers.
