After Eve Moonlit's death in EC 014, her children, Hänsel and Gretel, split her Original Sin into seven fragments, six of the fragments corresponding with the six reincarnated god kin freed from Sin the year prior. Housed in an object from their home along with their representative deadly sin, the Demons of Sin were scattered across the world along with their vessels.
Mantles of SinEdit
As their vessels moved around the Third Period throughout the centuries, each of the demons searched for suitable hosts to possess, forging contracts with the humans and influencing them to spread malice. Over time, the demons caused numerous tragedies through the humans under their influence for their amusement. In EC 325, the Demon of Gluttony was devoured by its contractor, Banica Conchita, and the human replaced it as the demon of its wine glass vessel.
During the Duel of Merrigod Plateau on January 30, EC 611, the Demon of Wrath was blown out of its vessel and into the Hellish Yard. Around EC 822, the Demon of Envy forcibly swapped bodies with her vessel's guardian, Kagura Octo. Assuming her identity, "Kagura" lived life as a human and birthed a daughter before fleeing from Enbizaka and eventually returning to her vessel.
After the Third Period’s destruction in EC 998, the sun god Sickle met with the demons and asked each of them to guide Allen Avadonia in meeting with one of their contractors. Agreeing with the request, the Demons of Sin helped guide the former chamberlain with meeting each contractor.
Biology and AppearanceEdit
Each of the demons possessed a unique appearance, ranging from resembling an actual biological animal to appearing as a simple mask. Many of the demons also had six wings and were capable of flight. Like humans, their superb intellect allowed them to innovate and adapt to unfamiliar situations and environments. Though their personalities typically varied in relation to the deadly sin they represented, all the demons acted in the interest of spreading malice and causing calamities in the Third Period.
Demons of Sin were also capable of manipulating magical energy, with each of them possessing a unique set of powers. In spite of their abilities, the demons were confined to their respective vessel of choosing and their main bodies had to remain there at all times, unless forcibly moved via magic. Despite this limitation, they could project extensions of themselves as doubles to possess and telepathically communicate with humans when needed. By forging contracts, the Demons of Sin could share their powers with humans; they could also influence their hosts' behavior via possession of the mind.
Conceptualization and OriginsEdit
- The Demons of Sin bear resemblance to the Seven Princes of Hell, powerful demons each aligned with a Deadly Sin who attempt to cause mortals to commit their sin; the demons' representative sins are similarly inspired by the Seven Deadly Sins.
- Several of the demons' true forms having six wings may be a reference to the six-winged Seraphim, rebellious angels cast out of heaven that eventually became demons; six is also a demonic number in some religions.
- Despite being referred to as the demon representing Sloth among the vessels of sin and inhabiting the Clockworker's Doll as her vessel, Eve Moonlit was not an actual demon herself.
