Crossover Anime: How Did I Become Iruma-kun?

Iruma's eyes were full of contempt, as if he were looking at maggots.

How could Leviathan, an ancient elemental demon god, allow himself to be insulted like this?

He dived into the deep sea, frantically swallowing seawater. In an instant, the entire sea level plummeted, and the air became thinner.

Seeing this action, Iruma frowned slightly.

"Is this the final, big move they're about to unleash?"

He quickly distanced himself from it and went up into the sky.

The already chaotic sea became even more turbulent, with lightning flashing and thunder roaring, as if it wanted to swallow everything up.

The entire island of Siren was uprooted by this massive gale.

"Damn it!"

Upon witnessing such a horrific sight, Mephistopheles hesitated for a long time before deciding to go and save the demons below first.

This level of combat is beyond the capabilities of demons.

"Boom boom boom!!!!"

Millions of sea creatures surged out of the sea, ranging in size from six meters to a hundred meters, an army that seemed to bring about the end of the world.

The massive army of sea monsters, blotting out the sky, roared at Iruma above.

"This is interesting!"

Iruma finally smiled, and the Conqueror's Haki erupted from the Rainbow Spear in his hand, instantly unleashing a torrent of black lightning.

"Go to hell!"

With a sinister smile, Iruma decisively plunged into the sea monsters.

"Roar!!!"

Seeing that the other party dared to come down, countless sea monsters rushed forward and began to fight him.

However, they greatly underestimated the strength of their opponent and had an inexplicable overconfidence in their own abilities.

He dodged the tentacles and claws of several sea monsters in quick succession, and with a raised hand, blocked the full-force punch of the deep-sea giant.

"Um?!"

The deep-sea giant was utterly shocked; all the blue scales on its body exploded, and countless black mists enveloped and devoured it.

"boom!!!"

The deep-sea giant threw another punch, this time even more terrifying, and it seemed tireless, relentlessly punching the tiny figure.

The residents on the coast, witnessing the frenzied battle, looked on with worry: "Are you alright?"

"It should be alright, right?"

"After all, that is the Rock King Emperor."

"If even he loses, then I'm completely finished."

The demons prayed in their hearts, hoping that Iruma could bring them hope and victory.

But looking at those terrifying and ferocious sea monsters, they felt there was no hope left.

Ultimately, the demons simply couldn't defeat those monsters.

But they still clung to a sliver of hope.

Iruma, who had been struck thousands of times by the deep-sea giant, thrust out his spear, and amber light erupted like a volcanic eruption.

"Immortal work!"

Under this boundless, murderous golden light, the nearly eighty-meter-tall sea giant was instantly overturned, its mountain-like right arm turning into countless pieces of flesh scattered across the sky.

Iruma teleported in front of him and grabbed the other's neck with his tiny, mosquito-like arm.

"Om!!"

In a flash of white light, Iruma grabbed the deep-sea giant by the neck and slammed it down hard.

"Crack!!"

In the void, an unseen, enormous glass shattered, leaving spiderweb-like cracks that stretched for kilometers.

A terrifying spatial rift tore the deep-sea giant and nearby sea monsters to shreds into countless pieces.

Golden light emanated from Iruma's body, dragon horns grew on both sides of his forehead, and his golden dragon eyes turned blood red.

In an instant, he shattered the void and charged away, causing chaos in the Milky Way and the collapse of stars wherever he went.

Even if there were millions of sea monsters, they could not stop him for a second; wherever he went, mountains of corpses and seas of blood were left behind...

The entire ocean was being stained red with blood at a visible speed.

"The more you kill, the more interesting it is!"

Iruma retracted his spear, which had been piercing through the rainbow, and raised his right index finger to the sky.

A burst of raging flames erupted from his fingertips, coalescing into a massive fireball nearly six meters tall.

The fireball's temperature was so terrifying that it caused the entire seawater to boil.

"The sun without mercy!"

With icy eyes, Iruma tossed the fireball in his hand.

The moment the giant fireball crashed into the sea, a terrifying sea of ​​fire engulfed an area spanning tens of kilometers.

Countless sea monsters turned into charred ashes amidst their wailing cries.

"Is this all he's got?" Mephistopheles' understanding had been completely overturned.

The golden dot in the distance weaved among the countless sea monsters, slaughtering them with impunity as if they were nothing.

The massive sea monster army was blasted into a vacuum by this attack.

The fireball continued to boil and steam the seawater, showing no sign of being extinguished.

The skin of the surrounding sea monsters was visibly red.

Just as the sea monsters were in danger, Leviathan, which had been hiding in the deep sea, was restored.

"Boom!"

Thunder rumbled across the sky as a colossal, sky-covering body burst forth from the sea.

Two, three, six, nine followed closely behind!

Nine enormous bodies enveloped the entire 2.8 space where Iruma was located, trapping him inside.

"If you can't beat them, you resort to ganging up?" Iruma's expression remained calm, showing no sign of being intimidated by the other party's appearance.

"You lowly insect, you will pay the price for defying the demon god!"

Leviathan roared and charged forward, its countless magical cages and iron bars tightly binding Iruma.

Nine enormous bodies, shrouded in black mist, opened their fangs and maws and charged towards him.

"Crack!"

Iruma used brute force to tear apart these magical seals, transforming into a bolt of lightning and arriving ten thousand meters above the ground.

Looking down at the nine enormous heads below, fragments of memories began to resurface in my mind.

"I was wondering why this place looked so familiar; it turns out it was waiting for me here."

The scene before him made him think of a line from a movie.

Chapter 401 In the name of the Rock Demon God, the remnants are put to trial!

Iruma crossed his arms: "I don't know if you're a corpse or alive, but now, you'll be forever trapped in this situation!"

"You call yourself a demon god, yet you can't even restrain me. It's utterly ridiculous."

Leviathan was utterly enraged by these words. Hundreds of blue magic circles appeared behind him, from which countless black water guns shot out.

The aura of death swept over us, as if it wanted to drag all living beings into hell.

"Sure as a rock!"

Iruma's entire body shone with golden light, surrounded by a rock shield.

These terrifying black spears were like dust before the rock shield, unable to even crack it.

"How could this be?!" Leviathan was truly astonished this time.

"What kind of monster are you?!"

"I can't sense any aura from you. You're not a demon god, nor..."

“That’s enough,” Iruma interrupted.

It's quite interesting that Leviathan 24, an ancient demon god, could see that he wasn't a demon.

"It's time to stop here. Next, I will drag the entire island into the deep sea. If you have the ability, then come and save them!"
