Genbu 100 Kick (玄武百烈脚 Genbu Hyakuretsu Kyaku; "Black Tortoise Hundred Rending Kicks") is a technique used by Kevin in Seiken Densetsu 3. He learns this technique only if he class changes into a Warrior Monk. This tech allows him to perform an powerful combination attack through creating a clone to strike twice as hard.
"Through the Warrior Monk's study of their body and the natural flow of mana in their course of study and training, this technique harnesses their refined mana to create a duplicate other of themselves, allowing them to strike twicefold onto their foes."
Kevin will start the technique facing his target to his front. Upon engaging the enemy, a clone of his mana will immediately emerge and cover the hind of the enemy, before they both rapidly attack the foe with a wild chained series of hard hitting attacks. As the dust that kicked up as a result of the attack settles, the foe then takes damage.
