Kuririn bends down as he brings his arms to his sides and charges up. He then brings his hands forward and fires two reddish-orange energy waves that follow his opponent like homing missiles, inflicting a great deal of damage.
Kuririn used this attack in his match against Piccolo at the 23rd Tenkaichi Tournament. Piccolo thought nothing of this attack and merely jumped into the air, but he did not realize that they had followed him and he almost got hit from behind. Though Piccolo managed to destroy the Double Tsuihikidan with his Eye Laser, this was merely a distraction as Kuririn appeared behind Piccolo and punched him in the face.
