Crossover Anime: How Did I Become Iruma-kun? Author: Red Center Boss

I unexpectedly transmigrated into "Welcome to Demon School! Iruma-kun" and became the protagonist.

The chairman is my grandfather, so I can be arrogant as much as I want, so what?!

Humble? Cowardly? Afraid of trouble?

does not exist at all!

From the very beginning and after turning evil, I'll crush any demon you may be!

"Sorry, I'm just that domineering!"

"Magic? Is your purity sufficient?"

"All scheming is useless in the face of absolute power!"

Asmodeus Ellis:

"As expected of Lord Iruma, I will follow you to the death!"

Chapter 1: I've already transmigrated?

The Demon Realm...

In this bizarre and twisted world, within the Dark Castle.

The bewildered young man was sitting on the sofa, dumbfounded as his hand was being held.

A strange, bald old man with horns on his head squatted down below and said, "Can you become my grandson?"

'Aminos! I'm still your father!'

Although he was complaining in his heart, he didn't dare to say it out loud.

In a daze, I no longer knew whether I was in a dream or in the real world!

All I remember is 'rewarding' myself in Clara's notebook just before I fainted...

After a period of time in a daze, he woke up.

The scene that greeted me as soon as I opened my eyes was something I, a die-hard fan of "Welcome to Demon School! Iruma-kun", found right before my eyes.

I immediately realized what scene and plot this was.

'So, I've become Iruma? Finally, I'm free from that 996 work culture!!!'

Thinking of this, Iruma lowered his head and asked solemnly, "Does it include the five social insurances and one housing fund?"

???

Sullivan was immediately filled with questions: "What are the five social insurances and one housing fund?"

Seeing the other person's bewildered expression, Iruma was now truly certain that this was not a dream. After all, no matter what kind of dream he had before, he could never escape the 996 work schedule and the five social insurances and one housing fund, which had almost become his nightmare.

Sullivan continued to play the victim, saying, "Although I don't know what the five social insurances and one housing fund are, I'm super envious of my friends showing off their grandchildren!!"

Become my grandson and I'll give you anything.

I'll spoil you rotten!! So, is that okay?!

Faced with Sullivan's pleading, Iruma naturally couldn't say anything, or rather, he simply didn't care.

"Okay!"

His tone was calm, as if he were talking about something ordinary, but only Iruma himself knew the truth.

Although he appeared calm and collected on the surface, he was actually panicking inside.

But deep down, he was also secretly delighted, wondering how many benefits he would enjoy by coming to this world as Iruma.

"Good! Good!"

"Next up is the surprise!"

Sullivan was thrilled to see him agree so readily, and swallowed back all the lines he had prepared, then snapped his fingers lightly.

"boom!"

With a sound of cotton bursting open, Iruma found himself wearing a strangely fitting school uniform.

Iruma feigned ignorance and asked, "You're not going to go to school by yourself, are you?!"

Regarding going to school, Iruma didn't dislike the teaching methods in the Demon World. On the other hand, he felt like dying when it came to schools in the human world.

Sullivan said with a beaming smile, "After all, you are my beloved eldest grandson, and I must ensure your complete protection, clothing, food, lodging..."

As he spoke, he pulled out a whole bunch of strange and wonderful things, including books with teeth and a bottle of potion that could talk on its own.

Sullivan continued, "After all, education is necessary, so I'll send you to a school in the Demon Realm!"

"You were taken around by your parents and didn't go to school properly, right?"

no problem!

The formalities have been completed!

Don't worry about anything, I'm your grandpa!

Ah~~~

The word "grandfather" is so beautiful!

We need to take a photo in front of the school gate during the entrance ceremony!

Iruma felt like his ears were about to fall off from listening to Sullivan's rambling.

It's hard to imagine how good-natured Iruma must be to get along with this talkative old man.

"Thank you, Grandpa, but I'm human. Is it really okay for me to go to a school in the Demon World?" Iruma asked, feigning ignorance.

Life is like a play, it all depends on acting!

Sullivan gave a thumbs-up to the question: "Don't worry, as long as it's not exposed, it won't be eaten!"

"Eat it?!?"

Before Iruma could finish his shock, Sullivan poured a whole bottle of purplish-red perfume over him.

Surprisingly, Iruma wasn't soaked to the bone. Instead, the liquid was quickly absorbed by his body, giving off a unique fragrance.

Sullivan patted Iruma on the shoulder and said, "Don't worry, Grandpa has made sure everything is foolproof for you."

This perfume can completely mask your human scent, so you can go to school properly!

After saying that, he snapped his fingers again, and the handsome red-haired cat-like man who had been standing behind him walked over. All four of his ears twitched, and his red undershirt and butler's uniform were perfectly wrinkle-free.

"Opera, now it's your turn to prepare dinner~~~"

"Yes, Chairman!"

Opera left the hall expressionlessly, leaving Iruma and Sullivan alone.

······

This made Iruma immediately feel an awkward atmosphere.

With Opera there, the atmosphere was relatively harmonious.

Now only the grandfather and grandson remain, and they really don't know what to say.

Sullivan continued sweetly, "Don't worry~ Let's go eat with Grandpa!"

After a less-than-ideal dinner and shower.

Iruma was led to his room, and when he saw the huge room and the luxurious bed, even he was shocked.

But none of these are the most important things, because on his way back from taking a shower, he actually heard the system loading sound in his mind.

Loading... Loading...

[System loading complete]

[Activate or not?]

Chapter 2: The Beginning and Invincibility

"Yes Yes Yes!"

Iruma practically smashed the system screen with his fingers.

totally unexpected!

It's bad enough that I was transported to this other world, but I even managed to awaken a system.

This made him instantly arrogant.
