Crossover Anime: How Did I Become Iruma-kun?

Mephisto used several defensive skills in practice to further strengthen the barrier.

"Bang! Bang! Bang!"

Each of these water arrows seemed to weigh a thousand pounds, crashing heavily onto the barrier.

Even with the blessing, countless cracks began to appear on the transparent barrier.

"It's actually this powerful?" Mephisto thought, forcing himself to burn his magic.

"The main body hasn't even appeared yet, and it's already caused such a huge problem. If it does appear..." 570

He simply couldn't imagine how powerful Leviathan would be after it was contaminated.

Originally just a member of a criminal gang, Six Fingers was enhanced to possess combat power comparable to himself.

Now strengthened by this strange power, who knows how terrifying its strength will be.

"Bang Bang Bang!!!"

The water arrows in the sky seemed endless, continuously attacking the Siren Island below.

Meanwhile, countless sea pillars in the open sea swept up the polluted and mutated sea monsters, which then surged towards this location.

“Bang bang bang bang bang bang!!!!”

Faced with this terrifying offensive, Mephistopheles looked terrified and unleashed all of his magical power.

He raised his finger and pointed it at the sea monster crashing down from the sky: "Space Slash!"

With a flash of white light, the sea pillars and sea monsters in the sky were all severed.

"Whoa whoa whoa!!!" The demons below erupted in cheers.

"As expected of Lord Mephisto!"

"His strength is truly extraordinary!"

"It seems the trouble will be resolved soon."

However, before the demons could laugh for long, the black outer sea suddenly rejected the towering waves.

"Boom boom boom!!!"

Mephistopheles' pupils constricted sharply: "It really is the Demon God Leviathan!!"

The towering waves formed a colossal marine creature, its enormous fluorescent body blotting out the sky.

Its head resembles a blooming chrysanthemum, with countless tentacles dancing around it.

"Roar!!!!"

Leviathan roared menacingly, and the entire ocean trembled at the return of its king.

The serpentine body writhed and twisted, its fluorescent lines flashing rapidly as if it were gathering magical power.

Under the desperate gaze of the demons, Leviathan condensed into a colossal water sphere.

The water sphere was so enormous that its terror and sheer size could be felt even from tens or hundreds of kilometers away.

"Leviathan, the ruler of the ocean!"

Mephistopheles' voice was trembling.

During the war between the demons and gods, he was the only being who could instill fear in all demons and the demon gods.

Its very existence is a tremendous threat capable of destroying the world, and its sudden appearance means that it will retaliate against the entire demon realm.

As the water sphere coalesces, the sea level rises instead of falling, constantly eroding the barrier.

At this moment, Siren Island was seen by Leviathan as a laughable glass ball that could be easily torn apart at any moment.

"Boom!!!"

Leviathan swung its body, sending out a massive, sky-covering water sphere.

The water sphere spun rapidly in the air, and its terrifying power intensified.

"Not good!" Mephisto contracted the barrier, compressing it to its limit.

The giant water sphere landed precisely above the Siren Island and crashed down on the tiny island below.

"boom!"

The magical barrier was like an egg hitting a rock when faced with the demon god's attack.

The once incredibly solid barrier shattered instantly, failing to withstand even a second of impact.

"Ice Age!"

Just as the water sphere was about to engulf the entire Siren Island, Iruma's voice rang out from above, almost echoing throughout the entire sea.

“Ka-ka-ka-ka!!!”

With a freezing sound, the giant water sphere was forcibly frozen.

The water balloon was less than half a meter away from the house.

If it only takes a few more seconds, the entire island of Sirens will be dragged to the bottom of the sea.

"Gravity Reversal!" Iruma raised his hand upwards, and the colossal ice ball soared into the air, hurtling towards Leviathan at an even faster speed.

? !

Mephistopheles was stunned by the horrific scene before him.

Is this a battle between demon gods?!

Each seemingly ordinary move can affect or even impact the lives of the demons.

Leviathan saw its attack being thrown back and twisted its body, formed from the ocean, to prepare to defend itself.

In an instant, countless waves surged forth, forming a massive shield in front of Leviathan, which turned its body toward the sea, preparing to use it to escape.

Iruma immediately sensed the other party's intention and flicked his finger downwards: "Gravity Acceleration!"

"boom!!!"

The giant ice ball, affected by gravity, smashed through the barrier like a cannonball and landed squarely on Leviathan.

"Roar!!!"

The Leviathan, struck by the impact, roared and manipulated the seawater to condense into countless tentacles that wrapped around the ice ball.

Under this immense and monstrous force, it was crushed into countless shards of ice.

"Wow, this is interesting."

Iruma was immediately seized by a mischievous impulse, never expecting that this monster would have such a trick up its sleeve.

"It's His Majesty the Emperor!!!"

The demons below, upon seeing the golden figure in the sky, all beamed with joy, as if they had seen a savior.

"It is Lord Rock King!"

"The Emperor has finally arrived!"

"This is Tate's (9) super demon!!"

The moment Iruma appeared, it was as if all the disasters were no longer disasters.

The demons completely forgot the crisis they had just faced and kept waving and shouting at Iruma above.

Mephisto came to his side and asked, "Where are the Six-Fingered Clan, Your Majesty?"

"They got away." Iruma said calmly.

"He ran away?!" Mephistopheles was incredulous; he knew the strength of the emperor before him.

How could we possibly let those five little trash escape so easily?

This was something he simply couldn't believe.

“That’s right.” Iruma looked at the Leviathan that had recovered in the distance: “Because of some being there, this thing was summoned to the Siren Island.”

"So I rushed back to deal with the problems here."

"I see.".

Chapter 399 is enough for me.

Mephisto breathed a sigh of relief. If even Iruma couldn't deal with them, it would have been a real disaster.

"So, what is that thing?"

"Sea snakes?"

When asked by Iruma, Mephisto shook his head with a wry smile: "That was the most primal demon god."

"Leviathan, the Ocean Demon God".

Leviathan?!

Iruma was somewhat taken aback, and once again focused his gaze on the enormous sea monster that stretched to the sky in the distance.
