Demonic Power: As the son of Sirtreize Lucifer and Cinder Fall, Sairevil possesses an incredible amount of talent. Sairevil's control over his demonic powers is stated as being well beyond what he should be able to do for his age.
Power of Destruction (滅びの力 Horobi no Chikara): Like Sirtreize and Eira, Sairevil also possesses the Power of Destruction inherited from his grandmother. Despite Sairevil's young age, he has shown to have finite control of his Power of Destruction, being able to shoot them like a shotgun as well as controlling its direction.
Enhanced Strength and Defense: Sairevil boasts a lot of physical strength and defense, a standard of the Rook. He can use this strength to lift heavy objects with ease and use them as projectiles or punch through hard materials such as metal. With his defense, enemy attacks have been known to bounce right off of him, including light-based weapons that would seriously wound or kill a regular Devil.
Pegasus Cloth: Because his mother, Cinder Fall, was a human, Sairevil was able to be born with a Sacred Gear. It resides in a crystal worn around Sairevil's neck until activated, when it becomes a full suit of form-fitting white armor. The crystal becomes more prominent by taking a large form in the center of the chest, while smaller crystals appear on each knee, elbow, and the back of each hand. Sairevil also gains a headpiece in the shape of Pegasus, alluding to the spirit within this Sacred Gear.
Heavenly Light: Pegasus Cloth grants Sairevil the ability to create and manipulate the light from Pegasus' wings. It comes from any of the crystals present on Sairevil's armor. Sairevil typically uses the Heavenly Light to augment his punches and kicks, and in using it, he has been called a "clutch performer" of Rating Games due to being a devil who is capable of utilizing a devil's greatest weakness without self-injury.
Pegasus Ryūsei Ken (Pegasus Meteor Fist): Sairevil performs hundreds of punches at the same time, which makes it look like small meteors as the Pegasus' Heavenly Light fires off from every punch. Sirtreize Lucifer states that it resembles Sairevil's use of the Power of Destruction, but it has yet to be revealed which technique Sairevil used as inspiration for the other.
