She also seems to have a "brother complex" shown when she gets jealous due to the other girls in his squad trying to gain his affection. As a female born into the Kusanagi Clan, Kiseki has the body of a demon with a soul of a human. She is the host of the Hyakki Yakou, the amalgamation of countless demons sealed within her which outwardly manifests through a blob of flesh covered in dismembered eyes and mouths. The demons grant Kiseki's desires while inherently assimilating anything it comes into contact with and adds to its ever-growing mass. it automatically protects her if her life is in danger, even though it is essentially immortal. Nothing has been shown to permanently kill her as her regeneration is extremely high and she can be resurrected given enough time, as she has survived multiple decapitations, poisons, and other torture devices. Even if the flesh is separated, it still retains its contact with its host body and can be remotely controlled.
