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 stronger variant of Diable Jambe developed by Sanji during the raid on Onigashima. After Sanji equipped the Raid Suit created by Germa technology, his body began to awaken genetic modifications similar to his siblings. Though Sanji rejected the path of becoming an emotionless Germa soldier and destroyed the suit to prevent further modifications, he came to terms with the powers that had already been awakened. Sanji then realized he can combine this new power with his old ones to form a stronger technique.

By combining the hardness of his exoskeleton with his Busoshoku Haki, Sanji's legs become capable of enduring flames of even greater heat than Diable Jambe. The flames of Ifrit Jambe are so intense that they turn blue, producing blazes resembling lightning. This also increases the speed and weight of his pre-existing kicking techniques, producing attacks that are both hot and fast enough to not only burn his opponent, but effectively shock them as well due to the sheer speed of the strikes themselves.

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 turns blue-white are considered to be the hottest, thus it coincides with Sanji using the hottest flames for Ifrit Jambe.
