Power Progression
The Underworld ranks devils by class, while wing count reflects their standing as devils rather than directly measuring combat strength. Leo Eligos, for example, had high-class strength while possessing only two wings 4 105.
| Stage / Realm / Level | Chapter | Notes |
|---|---|---|
| Low-class; typically two wings | 4 | First rank in the devil hierarchy. Leo still had two wings after gaining high-class strength 4. |
| Middle-class; typically four wings | 4 | Six members of Leo’s peerage later passed the Underworld’s middle-class promotion assessment 230. |
| High-class; typically six wings | 4 | Eligible kings receive Evil Pieces to form peerages. Leo gained his pieces on promotion, then acquired six wings through his Peerage Transformation trait 2 7 11. |
| Ultimate-class; eight or ten wings | 4 | Leo gained eight wings after recruiting Mahiru Shiina and ten after recruiting Ram and Rem 83 157. |
| Maou or Devil King class; twelve wings | 4 | Leo reached this class through his own strength and later displayed twelve wings 215 227. |
| Beyond the devil race | 231 | Feedback from recruiting Ophis gave Leo a transcendent race and divinity, transforming him into a Demon God 231. |
Background and Society
Devils were nearly driven to extinction during a prolonged war with angels and fallen angels. Their former nobility included seventy-two titled families, many of which were wiped out. The Underworld continued searching for surviving descendants of those families, including Leo Eligos 2.
In the human world, devils gain power through contracts: they answer summons, fulfill requests and collect an agreed price, which may be money, possessions or even a life. Because few modern humans perform traditional summoning rituals, devils distribute portable magic-circle flyers instead 2 10.
High-class devils with titles can receive Evil Pieces and use them to recruit a peerage. The pieces can reincarnate people of other races as devils and grant characteristics tied to their assigned roles. Existing devils can also join a peerage, sometimes seeking better training or connections to noble families 11 143.
- Stray devils — Devils who leave their clans or masters and run wild. Some are reincarnated servants who turn against their masters after gaining power; the Underworld commissions devils to hunt dangerous strays 21.
- Noble-lineage politics — Some established families oppose half-human heirs such as Leo, despite Underworld support for restoring surviving lineages 3 78.
Appearance
Devils can retain a human appearance while manifesting black, bat-like wings. Leo first reveals one pair and later develops additional pairs as his standing rises 1 7 83.
- They need not have horns or tails; Leo has neither when he reveals his wings 1.
- A stray devil whose unchecked power and desires altered his body became a scaled, grotesque creature roughly three meters tall 22.
Abilities and Weaknesses
Demonic power
Demonic power is the basis of a devil’s supernatural abilities. Through imagination and technique, devils can manifest phenomena such as destructive magic bullets; more complex or powerful effects demand greater skill 3.
- A newly reincarnated devil’s demonic power depends partly on individual aptitude 11.
- Devils are more powerful at night. New devils can find sunlight uncomfortable, while stronger light is more harmful to their bodies 10.
Reincarnation and peerages
Evil Pieces allow a high-class devil king to create a peerage. A standard set contains one queen, two rooks, two bishops, two knights and eight pawns 11.
- A piece’s role grants its recipient a characteristic; Yukino Yukinoshita’s bishop piece boosts her demonic power 11.
- Reincarnation can save someone who has died, as it does for Yukino and Asuna Yuuki 7 28.
- A peerage member’s potential affects the strength they gain after reincarnation 11.
Light and holy power
Light power and holy weapons normally threaten devils 10 157. Leo becomes an exception after feedback from his peerage remakes him into a “perfect devil,” removing those inherent weaknesses 157.
