Slide and Glide

Slide and Glide is the Quirk used by Koichi Haimawari.

Description
Slide and Glide allows the user to project an attractive/repulsive force from their hands and feet.

The user can slide across surfaces by lightly repelling themselves away from any 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. The Quirk can also be used to go backwards, shift from side to side and to rotate as well.

Koichi has also learned to cling to surfaces by attracting his hands and feet toward a surface instead. He can use this to shimmy up the side of buildings, as well as fully glide off of them as well.

By condensing the energy into a concentrated force on the palms of their hands, the user is capable of shooting out repulsion beams. The effectiveness can range from close up blasts, to light shots from a distance, to quick rapid fire, to even being able to directly pierce through an object.

Slide and Glide is also capable of limited flight, performing a mid-air jump which turns the contact surfaces on the feet into what are similar to rocket thrusters, allowing Koichi to boost into the air at high speed and high altitude. While his belief is that he can only perform two mid-air jumps before having to land, or else he will fall, it has been shown that he is capable of executing multiple mid-air jumps with no repercussion through sheer force of will.

Koichi has reached a point of versatility with his Quirk, where not only does his top speed rival that of Overclock, and his repulsions able to neutralize the effect of detonation blasts, but that he can also project his repulsion force field on any part of his body, including his back. He can even coat his entire body in his Quirk, similar to how Christopher Skyline's Flight Quirk functions, to act like a cast for his damaged body, and grant him light floating.

Weaknesses
After repeatedly falling headfirst during his childhood, 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 was also capable of levitation through sliding across the air, before Koichi's strict mother had beat it out of him at a young age. Upon rescuing Makoto Tsukauchi he instinctively used it for limited flight, and several years later learned how to execute full flight.

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 Ida, Koichi learns to brake by accelerating in the opposite direction.

The power of Koichi's repulsion beams have the capability of being able to dangerously pierce through anything, even human bodies if he so desired. However, Koichi intentionally holds himself back, specifically when using it against other people, due to Kazuho's concern over the deadly potential of the ability.
