2 USJ.

Rui looks at the piece of paper containing all relevant information of the man he is supposed to kill. Kisame Namikaze (pls bear I have no naming sense). It said on the paper that the man is rumored to have killed over 90 heroes and people alike.

By this time-a few hours after receiving this commission-Rui realizes that he may not be in his world anymore. A whole new system of heroes has appeared before him. Not only that, but quirks are also a prominent face in this new world. Luckily for Rui, he fits right in. Switch could be considered a quirk right?

According to Giran, Kisame should appear alongside many villains in a place called U.S.J for an ambush.

'Ironic, ambushing an ambush!'

If villains were anything like the guy who attacked him when he first landed here, he should be fine. He himself had faced off multiple Dragon-level threats back home. A few villains that bring him so much money should be fine.

He rests atop a roof of an abandoned building to get enough rest for the next day where the attack might happen.

Rui leaps across building so casually one might think he did it since he was born. His muscle has been honed to the maximum human potential by Garou that leaping across buildings did come as easily as breathing.

According to the paper, Kisame has a quirk that makes him have the qualities of a shark. A shark head with similar chomping power as a shark.

A shark head is something Rui had seen back home. It was actually someone Garou defeated quite easily as well, which gave Rui a confidence boost to an already overconfident ego.

In a matter of a few minutes, he arrives at U.S.J. A large glass dome when peered into reveals a multitude of trees and fallen buildings. But when peered closer, one can spot a huge army of villains coming out of a purple mist. The large array of people makes it hard for Rui to find his victim but when you are a man with a shark's head you really stand out. In no time, Rui had found Kisame.

He hadn't been trained in the art of assassination nor has he done any assassination job before. However, he has had assassins come and try take his life before and had analyzed his movements. A quick yet flowy and strong yet subtle steps and movements are needed for assassinations. It is no wonder why they fetch such a high price. Only those who have trained extensively could do it without a sweat.

He enters the dome through the top where there is a small hole. He squeezes through it and lands on a ledge. He sees a group of young kids standing on the entrance of the dome.

Rui dismisses the young kids and focuses on Kisame who has yet to show up. Rui finally finds Kisame but Kisame was rushing forward together with the rest of the villains. To not lose him, Rui switches with a villain next to him.

The villain switched was inexplicably confused as to how he ended up on a ledge.

Rui pulls back his balled-up fist and launches the missile to the Kisame's face who was unready for the sudden blow to his face.

Kisame's head was lobbed off and sent flying many meters and past many villains. This took the attention of many villains who focused their attention to Rui instead of the man with cloth wrapped around his head.

As the villains surround him, Rui recalls the movement best suited when surrounded by enemies.

Four-legged style dog martial arts.

An unorthodox method when he first saw it in action but could not deny its effectiveness. It mimics the movements of a dog, utilizing all limbs to attack opponents.

He lowers himself to the ground and took in a deep breath. As he feels the air flow into him, he allows the neurons in his brain to recall the movements he spent hours learning.

He leaps and smashes and crashes and slashes everybody aiming to get him. In conjunction with switch, he sets up surprise attacks by making the villains attack one another by switching at the very last moment. Monsters back home could make sure he gives his all but villains here? It was like every single one of them were tiger level threats.

Soon, blood splattered as villains get stomped and punched unconscious. Bodies start dropping left and right and a blood bath had unveiled itself.

Rui knows he was only supposed to kill Kisame but he was so having so much fun toying around with the villains he had forgotten that he was supposed to be an assassin.

He only stops once he sees a huge mass of black rushing to him at an amazing speed.

That same mass punches Rui square in the face.

Rui remembers this sensation. One that is similar to Garou beating the shit out of him to force him to react and counter with a certain forbidden martial arts style.
