Rappa took an orthodox stance. He hid his head behind his arms. The Man took off into a dash. Rappa, taken back by the Man's speed, threw a quick jab. The Man slithered around it, leaving a trail of after images in his wake. Rappa shot another punch, but the Man parried it, responding with a flurry of strikes to Rappa's midsection. To Rappa, it was nothing more than a tide of light blows flowing over his stomach. The Man was fast, really fast, but his strength could not overcome Rappa's durability. As Rappa swatted the Man away, the Man quickly spun in the air, landing on his feet.
The Man pulled his glocks out of his jacket, he stood into a strange martial arts stance with both guns in his hands. "No more games!" The Man said.

The two men ran at each other, every strike that Rappa threw, the Man parried. The Man slipped his arm up Rappa's, moving the glock closer to Rappa's torso, until the barrel contacted flesh.
The Man pulled the trigger, the bullet hurdled through the barrel, and pierced through the hardened skin of Rappa. A trail of blood followed the bullet as it left his body. The Man slid behind him, placing another bullet in his head. He skull burst open into a shower of crimson. The blood stained the Man's jacket.

The Man looked around the room. Aside from the two corpses on the floor, there were a set of parked cars, and a series of pillars that were sprinkled around the floor. He noticed a door on the other side of the room. It was grey, and it had an image of a staircase. interesting the Man thought.

Two bullets down the Man thought as he walked towards the door. When the Man opened it, he saw a staircase descending into a deeper layer. He kept his fingers off of the trigger as he zoomed down the stairs. As he approached the end of the staircase, he heard the sound of scurrying feet grow louder until he reached the bottom. There were four people: A little girl with white hair and a horn, and 3 men in plague doctor masks. One of them was short, wearing a morph suit. One was in a green jacket, and the other one wearing white.
The Man made haste, dispatching the shortest of the men with a bullet through the skull. Greymatter sprayed across the wall, coating it a dark shade of red. The Man fired another shot at the knees of the White coated man. He fell over instantly.

The Man watched with apathy as the white coated man tried to crawl towards him. While keeping one glock pointed at the man in green. He finished off the white coated man. "Sorry," the Man said, "DId I break your concentration?"
The man in green tensed his hand. Slowly moving his arm behind him. "What do you want? Why would the Musutafu Mauler be here of all places?" The man in green said.

The Man nodded over to the girl. "Your actions have piqued my interest, and I found another method of getting weaponry."

The man in green cleared his throat. He squatted down and dashed towards the Man. The Man let loose a swarm of bullets. The man in green weaved between the shots, stretching his arm to grab the Man. The Man dodged.
The two of the men engaged in a dangerous dance. The Man refrained from shooting, opting to drop his guns. The two were intertwined, each dodging blows, vying for an advantage.
The Man grabbed his opponent by the jacket, throwing him at the wall. The plaster chipped. The man in green touched the ground, the floor turning into a heap of spikes. The Man dashed out of the way, grabbing the girl and sprinting up the stairs. The busted through the door, running to the nearest car. He placed the girl down, watching the doorway, seeing the man run after them.

"I'll spare you, Overhaul, If you leave me alone." The Man said.

Overhaul, the man in green, decided to responded. "Well, look around, jackass. We both know that can't happen, Mauler."

The two men stood in silence. The little girl clutching the leg of the Man. The Man reached into his pocket, pulling out a bullet. The girl let go. Overhaul reached for the ground, the Man hurled the bullet. It cut through the air like a scissor through paper. The bullet penetrated Overhauls neck, a small stream of blood spilled out of it. As Overhaul reached for his throat, the Man ran up to him, faster than a blink of an eye. He used both of his hands to give Overhaul's neck a crushing chop. A sharp spray of blood left the neck. Overhaul's body toppled onto the ground, limp.

The Man walked over to the little girl, the look of shock plastered onto her face. "It's okay," the Man said, "That man will never hurt you again."

It was an early morning in the Midoriya household. The muted sound of the traffic outside oozed into the apartment, and a little girl was resting on the couch.

Izuku MIdoriya wasn't the tallest of men; he was only around 5'10. He had green hair and green eyes. His body was built well, it had the musculature of a wrestler with the leanness of a boxer. He went to the bathroom with a bag of Ice. He placed the bag in the bathtub. He started to brush his teeth. He took a glance at himself in the mirror. His eyebrow had a small cut, and a series of healed lacerations adorned his chest. He spat out his toothpaste, turning on the sink to get rid of the residue.

Izuku opened up the bag of ice, spilling its contents into a tub. He turned on the tap, waiting until the tub filled up. He took off his boxers and slipped into the bath. His mind began to wander as the cold overcame him.

Izuku felt his arms start to give up as he hoisted himself up the mountain. His hands were bloodied as he gripped tightly onto the jagged rocks which made up the cliff side. He managed to clear the edge, his weak legs triumphant as he stood on stable ground.
He looked ahead, and saw a small temple. He saw a small, bald man meditating under a shrine to the right of the temple. He didn't wear much. He was covered in orange cloth and he wore baggy pants.

Izuku limped towards him, if he was right, than the trip would not have been in vain. "Hey! What do you want?" the bald man said.

Izuku's knees fell to the dirt floor, they bruised as Izuku prostrated himself infront of the bald man. 'I have come to learn"

The older man scoffed, "And why would I want to teach a bag of bones like you?"

Izuku thought on this, "I know nothing, and have nothing to offer but an open mind."

Izuku got out of the bath, wrapping a towel around his waist. As he left the bathroom, he saw a little girl standing in front of it. "Um, excuse me mister mauler, are you going to kill me now?" The little girl said. Izuku's heart dropped.

"Oh, no no no. I only hurt bad people, you aren't a bad person." He said. Tears started to form in her eyes. Izuku hugged the little girl. She ran her hands over his back, feeling the deep crevices that were carved into Izuku. They're just like mine she thought

"You don't need to call me the mauler," Izuku said, "Izuku is fine. What's your name?"

"Eri." The girl responded.

Izuku proceeded to get dressed completely. He wore a dark blue tracksuit and red sport shoes. "Come on, let's get you some clothes."

Naomasa Tsukauchi was a patient man, but this case gave him the works.

3 seperate massacres happened within a week of each other. Each one with the same killer, but no consistent Modus Operandi.
On january 6th, a warehouse near the docks was hit. 18 men dead. Most of the bodies retrieved were unrecognizable. They were violently maimed by a martially gifted perpetuator. Their injuries were blunt, quick, barbarous; there was hardly any sign of resistance shown in the autopsy. These wounds could not have been caused by weapons, meaning that someone killed these men with their bare hands . Most of the bodies recovered were only identified through dna testing. The rest were left unidentified. A group of john doe entered the morgue that night.
A similar violent streak was seen on january 10th. It was at a diner. This time, the victims were sliced to pieces, security footage from the warehouse verified that it was the same person. Now, in a hotel, it seems like the perp is using guns. Why the change in weaponry? What do all of these places have in common?

From the corner of Tsukauchi's eye, he saw a man enter his office. He was tall, around 6'2. He had an athletic build and his hair was blonde. Red eyes and a cheeky smirk met Tsukauchi's gaze as he began to recognize the man in front of him. "Ground Zero?"

"Hey! I don't see anyone in a uniform around here, you can just call me Bakugo," The man replied. "You still on the Mauler case?"

"Unfortunately..."

"Well, you're in luck," Bakugo said. Tsukauchi noticed the file in Bakugo's hand. It was tossed onto the table, the contents slightly spilling out. "Your victims are Yakuza, all of them. Our Mauler is hitting gang hideouts."

Tsukauchi nodded. "Makes sense. But why these locations? There are a host of other gang dens the Mauler could go to. But these were some of the most heavily guarded. Did you find anything else?"

Bakugo cleared his throat, "Not really, the man's an enigma. When I'm on patrol tonight, I'll have to rough up some Yakuza, get some leads. But you have a point. There is something else to it, something deeper..."

Tsukauchi walked over to the coffee machine. "How do you like your coffee?"

"Black."
