It was me, Tatsumi!

Within the Imperial Capital's park, late at night, a fierce battle occured between three individuals. In the perspective of a normal bystander, it would have looked both unusual and bizarre at the same time. The three people fighting was a girl who may as well be the living mascot of pink itself who's currently holding a giant rifle, an older girl who could be mistaken as purple incarnate wielding giant scissors, and an orange-haired girl with the face of a sociopath giving orders to a giant dog with bulging arms and teeth that can easily grind meat. Their respective names were Mine, Sheele, and Seryu.

The area that served as their battefield were filled with smoking craters, deep gashes, and wrecked public property. No doubt an example of what the weapons all three of them wielded were capable of.

"Devour them Koro!"

The humanoid dog gave a beastly roar at who it's master wanted dead. He lunged at them while swinging his meaty fists in an animalistic and unpredictable manner. Both females evaded in an effort to distance themselves from the biological weapon. Wherever his fists struck the small area they previously stood on, craters formed. The girl holding the oversized rifle relentlessly shot at the dog, but would be futile since the Imperial Arm had a natural healing factor that allowed him to shrug off the energy bullets. The girl holding the scissors attempted to chop off his limbs to immobilize him, but again, proved to be in vain as the monstrous dog would just regenerate his stumps.

"Why can't this thing just die already?!" yelled Mine.

"How do we kill it?" Sheele asked as she avoided being one-shoted by the dog's oversized human fists and gnawing teeth.

"We need to destroy the core!"

"Where is it?

"Just keep attacking it! We'll find it eventually!"

And so, the macabre between two humans and a living weapon went on all because of an ambush that occured after a succesful assassination was made. Meanwhile, far from their location, there were two more people who have recently made a similar assassination involving terminating some drug lords. One of them - a brunette - snapped his head over to a particular direction. His eyes narrowed.

"Hm? What's wrong Tatsumi?" The other person - a blonde woman - asked her partner in confusion.

"My main character senses are going off," replied the young teen named Tatsumi as his gaze never left to what he was focusing on.

"Your... what?" the woman asked confused.

"It means that one of our comrades are in danger and are most likely going to die if we don't get there fast."

"What?! Then let's get over there!"

"Don't worry, I'll just use my final move to intervene!"

As soon as he said this, Tatsumi got into several fabulous poses that were the very definition of bizarre. The woman, whose name was Leone, could only look even more confused at what her 'little bro' was doing. He then got into one last pose, then yelled out three words.

"KONO DIO DA!"

After that, something even more bizarre happened. His clothes became more fabulous and flashy, his hair bled blond, and a yellow humanoid appeared beside him in the same pose as the former brunette was in. A green headband with a green heart also appeared on his forehead

Unbeknownst to Leone, Tatsumi had channeled the soul of DIO in order to use the ancient technique that the vampire lord once used.

He then threw his arms to the side, leaned his upper body back, and yelled out a battle cry.

"WRRYYYYYYYYY!"

Tatsumi and the yellow humanoid jumped and soared upwards into the sky, leaving a surprised Leone behind. Only one sentence went into her head.

'...What, the fuck'

What the fuck indeed.

Back at the ruined park, things weren't looking so good for the members of Night Raid. Mine suffered a broken arm after getting caught in Koro's grasp, after which Sheele used her giant scissors to slice his arms off to free the sniper. It didn't help that the airhead was beginning to suffer from slight fatigue, evident by her slight panting. What's more, the Teigu changed appearance, now sporting red fur and looking like nightmare fuel.

All in all, it really wasn't their day. Not to mention Seryu was looking more deranged by the second.

"Yes! Justice shall be laid upon you, evildoers! I, Seryu Ubiquitous, will bring you to your dea- huh?" Seryu made a sound of surprise while looking upwards to the sky above.

Both Mine and Sheele gave curious looks to the police girl, before putting their attention to the sky as well. They became similarly surprised at what they saw. Up above, they saw something approach the ground at high speeds, though it was difficult to tell what it was due to it being nighttime, all they knew is that it was getting closer. What caught all of them off-guard was someone yelling, which came from the falling anomaly.

"RODA ROLLA DA!"

Before they knew it, the object crashed into the ground; specifically where Koro stood.

"KORO!" Seryu screamed in worry. Mine and Sheele had their eyebrows raised from the bizarre spectacle before them. The initial impact kicked up a lot of dust, so it was difficult to see what crashed. When the dust cleared, a strange yellow contraption with two giant grey cylinders on both the front and back was revealed to all three individuals. A person also stood on top of it while surrounded in a yellow flame-like aura with a yellow humanoid beside them. To all three, he looked familiar. They heard chuckling coming from the person.

"You thought this was going to be a flawless ambush. But it was me, Dio!"

Before they could continue to mentally process this, the contraption began to shift, revealed to be Koro trying to move it off of him.

"Hurry Koro! Get out of there and finish off the scum!" Seryu barked orders at her Imperial Arm, having regained her composure after the unusual stunt before her.

"NO! YOU WON'T ESCAPE FROM ME!" Yelled the person on top of the contraption. He and the humanoid started to slam their fists repeatedly onto the machine with Koro doing the same, all the while yelling the same word nonstop.

"MUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDA-"

Both reared their fists back for one more punch.

"MU-!"

And struck with all their might.

"-DA!"

As soon as both simultaneously struck at once, the contraption started to emit smoke, along with a few fires breaking out. Both the person and yellow humanoid jumped off into the sky before the contraption exploded in a ball of industrial fire and smoke. The person landed between the three females, who now got a better look at him.

"TATSUMI?!"

"JUSTICE PARTNER?!"

Tatsumi grinned at his fellow assassins.

"That's me!" He said enthusiastically. Mine pointed at him using her good arm.

"Hold on! How were you able to do that?!" Tatsumi's only answer was a shit-eating grin.

"Sorry, main character secret!" This served to piss off Mine. Sheele was curious on why his hair color was now blond.

"Listen here country bumpkin-"

Whatever Mine was going to say was cut off as a bestial roar came from where the contraption exploded, revealing to be Koro who growled dangerously at them.

"ARE YOU KIDDING ME?! IT STILL WON'T DIE?!" Yelled Mine in disbelief.

"KILL THEM ALL KORO!" Seryu commanded, her anger and bloodlust further growing from finding out her 'partner of justice' turned out to be associated with these 'evildoers'. Koro lunged at them, swinging his fists in a manner that they'll be unable to evade in time.

Tatsumi only gave the biological Teigu an unimpressed look, before the yellow humanoid appeared by his side once more.

"MIne, Sheele..." Both girls looked at him, "...leave the rest to me."

As the words left his mouth, the humanoid began to ripple the air around all three assassins, before it all came out along with two words.

"ZA WARUDO!"

Everything became negative, along with the sound of a clock ticking and reality distorting. It was short lived because it receeded back into Za Warudo, who successfully froze time and caused the surrounding to be a bit grey. Mine, Sheele, Seryu and Koro were all trapped from the effects of time freezing.

"Time has now frozen," Tatsumi said deviously while brandishing his short sword. He rushed towards the now still Koro and slashed him repeatedly along with Za Warudo punching it nonstop with his superior speed and accuracy. Eventually, they found the core, prompting Za Warudo to shatter it in one strike. Tatsumi sheathed his sword and cancelled the time-freezing effect.

"Time will now resume."

With that, color returned to the environment and the laws of physics continued on. In the perspective of the three females, it appeared as Koro getting close, then exploding in a gory mess.

"KORO!" Seryu screamed in disbelief as her Teigu was destroyed for good. Mine and Sheele were shocked at this. They had lots of trouble trying to take down that biological weapon, but the newest recruit to Night Raid was able to kill it off without trouble.

"H-How did you do that?" Mine asked wearily. This time Tatsumi gave an actual, but somewhat vague answer.

"I froze time, what else?" Was all he said before Za Warudo appeared again with his arms crossed.

"What Teigu did you use?" Asked Sheele. Tatsumi raised an eyebrow.

"You mean my Stand?" Both girls gave him confusing looks.

"Your... what?" Both asked simultaneously. Their attention was then turned towards the sound of gunshot, with Za Warudo catching a bullet between his right index and thumb.

"EVILDOERS! YOU LOT ARE EVERYWHERE! YOU'RE ALL THE REASON CORRUPTION EXISTS!" Seryu screamed nonsense as the reality of her most trusted comrade being killed caught up to her, resulting her being caught in a fit of rage that's making her scream bloody murder. Before she could go on about her rambling, a yellow fist smashed through her head, instantly killing her.

"Man, I thought she'd never shut up," said Leone, with her Imperial Arm Lionelle activated, giving her more animalistic traits.

"Oh, hey sis," Tatsumi said casually like it was Tuesday. Leone gave him an annoyed look.

"Tatsumi~! Why'd you leave me behind like that?!"

"Sorry, I got caught up in the moment."

Leone huffed in annoyance before she made a questioning look.

"What kind of Teigu did you use that made you all... that?"

Before Tatsumi could respond, all four members of Night Raid were surrounded by the Imperial Police.

"Halt! By the order of the law, you are all under arrest!" Yelled one of them. Acoustic guitar started playing in the background.

All four of them - except Sheele - thought one thing.

'Fuck.'

The soldiers all opened fire on them, prompting all of them to make a break for it.

"Za Waru-!"

TO BE CONTINUED

Tatsumi eventually ascended into heaven and became the ruling god of his world. Along with having a harem of beautiful women.

This first came to mind after watching a YouTube video called Squidward unleashes ZA WARUDO!. Before anyone asks, yes I'll still focus on getting out the next chapter of One-Punch Tsukune.
