Crossover Anime: How Did I Become Iruma-kun?

"The markings are too unsightly; we can only make them cooler."

As he spoke, Iruma altered the Sun Breathing Mark, making the mark flow like fiery clouds, its surface as red as the blazing sun and golden fluff.

The once innocent boy's aura changed drastically, but it quickly disappeared and was hidden away.

"Perfect, from now on, I am you, and you are me."

"Snapped!"

As wills shift, one side disappears, and the other takes over.

Tanjiro Kamado opened his eyes, and his originally black hair turned as red as the blazing sun. His red eyes were filled with contempt and indifference.

Time resumed its flow at that moment.

"Huh?!" The demon who was fighting him instantly distanced himself, looking at the boy in front of him with fear in his eyes.

"Who are you?!"

"Where did that brat go?!"

Upon hearing this, Tanjiro suddenly realized, "Sorry, sorry, I forgot to change your brains."

"World, listen to my will!"

Chapter 458 You're telling me this kid is human??

"Kid!!!"

After the world's will was altered, the demon immediately recognized Tanjiro (Iruma) and roared as it charged toward him.

Sensing the changes and increased strength in his body, Iruma frowned slightly. Compared to his own body, this was on a completely different level.

It's practically made of paper.

However, the strength of what he saw as paper was already the limit that this world could withstand.

Looking at the hideous demon, Iruma remained unfazed. He focused all his breathing, as if he had entered a lightning-fast state, where everything was slowed down a hundredfold.

He leisurely circled around behind the evil spirit, but in the spirit's eyes, he vanished in an instant!

"what?!"

"Where did they go?!"

"Behind you, you idiot." Iruma looked at him expressionlessly, casually swinging the old axe in his hand.

The demon exerted force with its feet and kicked hard at his chest, but Tanjiro simply punched it away.

Feeling the tingling sensation under his feet, the demon exclaimed in disbelief, "You brat, are you a monster?!"

"Being called a monster by a monster is a rather strange feeling."

Iruma twisted his cracking neck, his voice icy: "However, I'm not really interested in the breathing techniques of this world. On the contrary, Sekiro's swordsmanship, which he focuses on with his heart, is much more interesting."

"927, what nonsense are you spouting?" The demon couldn't understand what the other party meant by "the world" and "Sekiro."

All I know is that since just now, the kid's tone of voice has changed, as if he's become a completely different person.

The disappearance of that gentle feeling has turned into a kind of cold-blooded killing intent!

Iruma assumed a lunge stance, held the axe horizontally in front of him, and concentrated his breathing. In an instant, black waves of ink swirled around the axe.

This shockwave was like flames, or like splashed ink, pitch black.

"I've never seen a breathing technique like this before!" The demon took several steps back upon seeing this bizarre scene. "Wait a minute, how can you, a monster, use a breathing technique without a Nichirin Blade?!"

"It's simple, because I'm above everything."

"Ink Breathing, uh..." Iruma had just come up with a name for the breathing technique, but he got stuck on the name of the move itself.

"The breath of ink, the form of ink staining the setting sun!"

In an instant, Iruma swung his axe repeatedly, and countless terrifying waves of ink-black sword energy engulfed the evil spirit.

The entire area within a hundred meters was enveloped by this terrifying attack, with waves of ink surging forth in a powerful and vigorous manner.

It leaves the enemy with absolutely no blind spots to dodge.

The demon was instantly sliced ​​into countless pieces by this move, leaving only its head staring fiercely at Iruma.

"You monster!"

"I already said, it feels really weird to be called a monster by a monster."

Iruma walked up to the demon, kicked its head like a ball, and then used his broken axe to pin it to a tree with precision and ruthlessness.

The mountaintop fell silent once more, everything shrouded in stillness except for the rustling of leaves.

The demon was already terrified at the sight of this strange boy.

How is it possible for a monster to use breathing techniques without a Nichirin Blade?

Just as Iruma was about to smash the watermelon with one hand, a pair of old hands pressed down on his shoulders.

The figure standing behind him wore a red tengu mask, with short white hair peeking out from under the hood.

"Ordinary attacks alone are not enough to kill the evil spirit."

Urokodaki's voice was hoarse. Although he was already old, the calluses on his hands from years of holding a knife were still there.

Faced with this suddenly appearing master, Iruma remained calm: "I know, I just want to beat him up a little more before sunrise."

This was the first thought that popped into Urokodaki's head, but he immediately rejected it.

After all, Giyu had written in his heart that the other party's entire family had been killed by the demon, so it was inevitable that he would be angry at the demon.

But why does the boy in front of me show no emotion at all?

Urokodaki was puzzled again; the thing standing in front of him was more like a tree than a person.

There was no breath, no emotional fluctuation.

Just as the two were talking, Nezuko seemed to sense something and quickly hid inside the bamboo house.

A short while later, the dazzling sun rose from the east.

When the light shines on the earth, all evil and coldness are dispelled.

"No! No! I don't want to die!!" The demon struggled and shook its head, but to no avail. It could only be burned to ashes by the sunlight.

It looks pretty good.

Iruma was quite pleased with the scene of the demons dying before his eyes. Indeed, watching the enemy turn to ashes was far better than letting the enemy live.

Having spent so long in the Demon Realm, I've only ever killed chickens, ducks, and geese. Now, I've finally found a place where I can go on a killing spree!

There was still no emotional fluctuation. Was she hiding it very well?

Linglong was very puzzled, but that was all. Only after he buried the victims did she come to Iruma's side.

"You're the boy recommended by Giyu Tomioka, Tanjiro Kamado, right?"

“That’s right.” Iruma remained completely calm, without even a micro-expression.

"Your courage is not bad. Now, let me test whether you are suitable to become a Demon Slayer Corps swordsman."

"Bring your sister along!"

After a while——

Urokodaki fell silent as he watched Iruma follow closely behind. He had already used his full concentration breathing technique, but even with that enhancement, he still couldn't shake off his opponent.

What kind of monster is this kid?

Is this still a human being?!

What teenager of thirteen or fourteen could possess such a powerful physique and strength?

"Can you keep up?"

Iruma smiled and said, "Then you really underestimate me."

The journey was greatly shortened by several times as the two ran, and they returned to the deep mountains where Urokodaki lived before afternoon.

The two stood in front of the door, both of them sweating and panting from exhaustion.

Meanwhile, Iruma behind him remained completely unfazed, showing no signs of being affected or changed.

This outrageous scene made Urokodaki wonder if this was the offspring of some powerful samurai from the beginning.

Looking at the small wooden house that fit the era, Iruma asked calmly, "Am I qualified now?"

"I can only say it's half right." Urokodaki didn't believe that nonsense.

Could this kid be some kind of omnipotent god reincarnated?

"The next trial will be in the mountains. Leave your sister here until then, I will take care of her."

"That's troublesome."
