Ice Devil Slayer Magic
Ice Devil Slayer Magic (氷の滅悪魔法 Kōri no Metsuaku Mahō) is a Caster Magic and a form of Devil Slayer Magic that utilizes ice. Like other Slayers, the user is able to consume external sources of ice, even ones formed from nothing, in order to replenish their strength and enhance their power, as well as having a tremendous resistance to the element of ice. Additionally, the user is able to somewhat control the ice of others and is able to just as easily freeze a large scape of land with a mere flick of their wrist. The Slayer's freezing ability is notable; when Gray Fullbuster received Devil Slayer Magic, he was able to freeze the wind in twisters created by a Demon easily. Unlike other Slayer Magics, this Magic allows its user to obtain a basic analysis of a Demon's bodily composition based on sight alone. This form of Magic can also be used to work well with Ice-Make to deal far more effective damage in battle.


 * Ice Devil's Rage (氷魔の激昂 Hyōma no Gekikō): The Devil Slayer's equivalent to the Dragon Slayer's Roar and God Slayer's Bellow spells. The user, after inhaling, releases a large purple blizzard of cold air, ice and (seemingly) snow from their mouth, directing it towards an area of their choosing. The blizzard inflicts great damage upon those it contacts, causing everyone unable to resist it to be sent flying away with great force, as well as leaving behind a trail of destruction in its wake, heavily damaging the area it passes through.
 * Ice Devil's Zeroth Long Sword (氷魔零ノ太刀 Hyōma Zero no Tachi): The user covers their right fist with their left palm and separates them, creating an ethereal sword in between their two hands that delivers a swift cut to the target while encasing them in solid ice.
 * Ice Devil's Zeroth Destruction Bow (氷魔零ノ破弓 Hyōma Zero no Hakyū): The user creates an intricate bow made of ice and charges it with an ice arrow that is fired at the target at high speeds. Once the arrow makes contact with its target, it turns into a spiky array of ice.
