Sylph Images

Sylphs (氣精 (シルフ)  Shirufu) are a low to mid-level class of Demon that possess the air and are related to the King of Spirits, Azazel.[1]


Sylphs are demons of air. Appearing as small females with wing like arms, they can be invoked by producing elements they like, such as fire or water.[2]

While normally Sylphs, like Naiads and other elementals, do not possess fatal verses, Lewin Light somehow developed one consisting of a single word 'Mortem' ( (モーテム)  Mōtemu), the Latin word meaning 'death'.[3]

Powers and Abilities

Air Manipulation: Syplhs possess the ability to manipulate air currents, able to replace the stagnant air in a room with fresh, clean air in a matter of moments.[4]

Cutting: While not entirely clear how, Sylphs can cut people by passing them quickly. While painful, it does not seem to cause much damage over all, appearing akin to a paper cut or similar injury.

  • Circular Saw (サーキュラソー Sākyura Sō): A sylph manifests above the hand of its summoner, its lower half spinning rapidly to create a disc-like blade.

Tracking: Sylphs have been shown to be used in techniques for tracking targets.

  • Sylph Bell (氣精 (シルフ) の鐘 Shirufu no Suzu): A sylph is used to place a mark on a target, allowing their summoner to know their rough location at all times.
