The user can slide across surfaces by lightly repelling themselves away from the surface. The sliding gives the user great speed, initially allowing the user to travel as fast as a bike, though Koichi has since proven to be able to move at speeds similar to a speeding bus. This Quirk can be used to slide up the side of a building. The Quirk can also be used to go backwards and side to side and to rotate.
Koichi has stated that this Quirk can make him move far faster than a bike, but doing so is dangerous, as he has no brakes, and his power does not prevent him from taking damage from his Quirk. However, after receiving advice from Tensei Iida, Koichi learns to brake by accelerating in the opposite direction. His top speed is yet to be known.
Koichi has learned to cling to surfaces by repelling his hands and feet toward the surface.
After being repeatedly punished for floating, Koichi's control of his Quirk weakened and he needed to contact a surface in at least three places before he could slide across it. It is also capable of limited flight which Koichi's strict mother beat out of him at a young age, until upon rescuing Makoto Tsukauchi did he remember.
- Kowtow Evasion (土下座で回避 Dogeza de Kaihi?): While bowing, Koichi slides backwards. It is first used to avoid Soga Kugizaki's kick.
- High Speed Double Leg Trip: This technique allows Koichi to shoot down his enemies easily by extend his leg sideways and hook his opponent's legs, tripping him.
- Wall Cling: Activating it by accident at first, Koichi is able to turn the repulsion force emitted from his limbs into an adhesive force; allowing him to stick to walls.
- Scrappy Thrust Style: By concentrating on one limb Koichi can fire a repulsion beam out of that limb. He is able to fire consecutive light repulsion beams.
