Using the Shadow Clone Technique, Naruto divides himself in five. One clone punches the target in the face, as they yell "U-ZU-MA-KI", the three of the other clones kick the enemy into the air. Then, while the enemy is launched in mid-air, the original body assaults it with a somersaulting heel drop while yelling "Naruto Rendan!", sometimes using the posture of the first body for leverage to achieve the airtime.
The name of the technique is directly lifted off Sasuke Uchiha's Lion Combo, which was based off of Lee's taijutsu. However, it can be said to be a Naruto-original ninjutsu.
