|Shadow Devil Slayer Magic|
Shadow Devil Slayer Magic (影の滅悪魔法, Ei no Metsuaku Mahō) is a Caster Magic, Lost Magic, Slayer Magic, and most obviously, a Devil Slayer Magic that allows the user to manipulate, generate, and absorb the element of shadows.
Iriel Developed the Shadow Devil Slayer Magic while he was in captivity, from his old village head as he passed away and his body disappeared into dust. Though Iriel wasn't able to find the Warden he swore upon Headmaster's death that he would defeat him one day. Iriel is able to use his Shadow Magic, to cover him and his opponent, and is able to envelop his enemy in a cocoon of shadows, suffocating them to where they lose consciousness or die. In this form he obtains a mask and 2 extra arms of shadow's along with his feet/boots gaining a shadow aspect. His hair also turns black and all around his body he gains an outer shell like an armor.
Shadow Devil's Rage: With this Iriel releases a powerful blast of shadow magic from his mouth and is equivalent to the Dragon Slayer's Roar and God Slayer's Bellow spells. The Blast inflicts great damage upon those it contacts, causing those who were hit to be sent flying away with immense force, as well as leaving behind a trail of destruction in its wake, heavily damaging the area it passes through.
Shadow Devil's Hammer: Iriel coats his arm in shadow aura and uses his other aura arm to hit his opponent slamming them into the ground
Shadow Devil's Cocoon: Iriel goes into his opponent's shadow grabs them and drags them into the shadow with him. Once in the shadow the opponent starts to suffocate and loose conciseness. Iriel can either keep them there to die or until they pass out.Shadow Devil's Mutilation: Iriel is able to attack his opponent's shadow, as in whatever part of the shadow Iriel hit's, the body takes damage as well.Shadow Devil's Cage: With this technique, Iriel encases his opponent in a cage made of shadows and forms blades out of the shadows that strikes his opponent from all sides
Shadow Devil's Claw: Iriel charges at his opponent with a claw like attack covered in shadows.
Shadow Devil's Cannon: While in this form, Iriel uses all four arms to develop enough magic to fire a cannon on equal power to the Devil Slayer's Rage technique.
Slayer's Dance:Seven Sword Strike- Making use of his 4 arms Iriel makes 3 more swords out of shadows and charges at his opponent spinning and slicing at his opponent.
