Black Leg Style/Ifrit Jambe

An exoskeleton, muscle, and speed... all of which increase strength. Add the Busoshoku Haki I've developed to the exoskeleton, and my legs are tougher, capable of supporting even hotter flames!!!

Ifrit Jambe is a much stronger variant of Diable Jambe developed by Sanji during the Raid on Onigashima. Having equipped his Raid Suit three times during the Wano Country Arc, it awakened his inert genetic modifications, granting him powers similar to his siblings. Accepting the modifications but choosing to cut ties with Germa through the destruction of his Raid Suit, Sanji combined his new powers with his old ones to develop a far more powerful technique.

Through combining his exoskeleton and augmented muscles and speed with his Busoshoku Haki, Sanji's legs became capable of enduring much hotter flames than before, turning blue while producing blazes resembling lightning. By using the vastly increased speed and weight behind his strikes in conjunction with incredibly intense flames, Ifrit Jambe makes his kicking techniques incomparable to before.

Trivia

 * An Ifrit is a powerful type of demon (or jinn) in Islamic mythology that are often associated with the underworld and identified with the spirits of the dead. In Islamic folklore, they are a class of generally ruthless and wicked chthonic spirits formed out of smoke and fire. In modern fiction, they are almost always associated with the element of fire.
 * In real-life, flames that turn blue-white are considered to be the hottest, thus it coincides with Sanji using the hottest flames for Ifrit Jambe.
