Personality Quanxi's Four Wives

All four girls were extremely loyal to Quanxi, often accompanying her on missions and spending their leisure time together. Not much is known about both Long and the stitched fiend as they rarely speak in most of their appearances with the stitched one being completely silent, but Pingtsi reveals herself to be a cheerful and energetic girl who loves eating food and Cosmo appears to be an insane fiend who only speaks "Halloween!" as her only word only to be revealed that she is an extremely intelligent fiend with an affable and happy-go-lucky personality that guards the Akashic Records stored in her own mind.

Quanxi‏ Personality

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.[4] 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.[5] 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.[6][7][8] 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 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, which hinted at a past friendship between the two.
