Blue Star Planet Earth.

Shanghai, China

In a luxurious Mansion, An handsome young boy was watching lastest episode of the anime 'Welcome to demon school! Iruma-kun.'

"I truly envy Iruma's life."He muttered with a sigh.

My name is Mu Chen, college student, my family was very wealthy family.

So, I didn't have many struggle in life, I had a very good family, who cares about me, spoiled me and dotes on me.

But there are also many superficial people around me.

That's why I became an otaku, and distance myself from those superficial people.

I have watched many anime, movies and Manga.

And 'Welcome to demon school! Iruma-kun' is my favorite anime, because in this anime characters friendship didn't feel real to me.

Like Iruma and Clara friendship, really didn't feel real to me.

That's why I love this anime, because Clara with her bloodline magic can perfectly re-create or summon any item and object she has seen previously.

When Clara was introduced, I literally cried seeing Clara being used by others for her ability.

Because, I was in the exact same position she was in, To get friends I had to pay them with treats as a kid.

As we got older their greed grew, I made many friends but non of them have kind regards towards me.

Honestly, I still don't have any real friends, but atleast I don't have to pay someone money to be my friend now.

While seeing her at first, it brings up bad memories of my life! But Clara was a anime character.

Later, she got everything Best friends, Soul mates and her family.

In comparison with her, I lost everything My Family, My Love and so called friends.

My parents passed away in a car accident, I don't if it was murder or an accident.

Anyway for me it was an life changing event, As days and months passed after my parents death.

I became even more lonely, after some time a girl entered my boring life.

We stayed in that relationship for 2 year's and just like other modern generation relationship.

She broke up with me, I do not have any regrets because we had a good time.

She as well had no regrets I guess... Anyway now we're just strangers with memories.

As he was immersed in his sad memories, A voice sounded in his mind.

[Ding]

"Huh"

[Detected a suitable Host, Binding with the host.]

...

"What the fuck! Who's is there?"I shouted, looking around. I was startled, but there was no one in sight.

[No need to worry host, It's your friendly neighborhood Ten times Template system.]

The voice sounded again in my mind,But after listening to him I was little excited.

"Wait! Ten times Template system, Does this mean I can get a template of any character with 10 times their original power."

[Of course host, you can get the template of any fiction characters and travel to different world with the systems help.]

"Haha, that's a nice function you have system." That's very good now I can travel to my favorite anime welcome to demon school! Iruma-kun.

"So how can I select the Character Template, System?" I asked eagerly.

[First you have to spin the character template wheel, where you will gain your character template, which with enhance Ten times the original character power.]

Suddenly a blue panel appeared infront of him, it contains a wheel on top of it there is one world 'Ten times Character Template' with the word 'Spin' in the center.

He press the spin button, It began to move quickly there were many famous characters in the spin.

Please be Saitama, please be Saitama.

15 seconds later... The spin stopped at Giyu Tomioka, Water Hashira with demon slayer mark.

"Not bad," I muttered, trying to console myself.

[Detected that demon Slayer mark is dangerous for host, do you want to exchange Demon Slayer mark for something else.]

Huh, can I play like that it's really a awesome system. But what should I exchange the demon Slayer mark for.

Demon Slayer mark have it's own advantage and disadvantage.

Advantage: The Mark, can enables slayers to activate the Red Nichirin for their swords, which drastically increases their demon slaying ability, improves one's physical strength and endurance, and even provides access to the mysterious Transparent World.

Disadvantage: Demon Slayers who have awakened their mark are said to, without exception, die before reaching the age of 25, except for Yoriichi Tsugikuni.

[You can choose the world first host, then it will be more easier to exchange.]

"Alright, then."

"I choose MAIRIMASHITA! Iruma-kun system." I said excitedly.

[Okay host, Analyzing the world.]

Few seconds later...

[Detected it is a dangerous world, for the current host even with the ten times Giyu Tomioka template.]

[Changing the body structure, battle experience, sword styles of Giyu Tomioka.]

"What's going on now? System?"

[Changes successful]

[Acquired other world Gene: High Human/ Ancient human.]

[Acquired other world energy:Mana.]

[Acquired other world Water Magic affinity.]

[Giyu Tomioka acquired new memories, battle experience and sword techniques/forms.]

[Now host can travel to MAIRIMASHITA! Iruma-kun safely.]

"Um, System? What did you just do?"

[Since Mairimashita! Iruma-kun has demons, magical beasts, and deities, it's far more dangerous than Earth. So, to help the host survive In that world, System have upgraded Giyu Tomioka's abilities.]

[High Humans resemble humans but have three times the strength, lifespan, and senses, along with the ability to use Mana and magic.]

[This upgraded Giyu Tomioka fought stronger demons and has more refined combat skills. And most importantly, his Water Breathing is now actual water and five times stronger than the original.]

[This upgraded version could single-handedly defeat Muzan Kibutsuji and the entire Upper and Lower Moon demons.]

At that moment, I was too shocked to speak.

"Fuck that's literally overpowered, love you brother system! Then can I handle the demon slayer mark now system." I asked with some expectations.

[Ahem, Actually, due to some calculation mistake the Demon Slayer Mark is now even stronger, so it's still risky.]

"So, can't you just fixed the calculation." This system is too overpowered can't he do that.

[Sorry host I can't do that. Because I'm bound by certain rules.]

"Okay." Rules what rules it is more powerful than this system! Fuck. How powerful is that rule then.

Ahh,Why I am even thinking about this it's not my problem anyway.

"Umm, system brother will I get Nichirin sword for free." I asked shamelessly.

[Yes, but a kind reminder host Nichirin sword can't handle your mighty power.]

"Shit! Really forgot about that." He said while cursing.

"Hmm, can I exchange Demon Slayer mark for the Necrosword in MCU system." I asked with some hope.

[Don't joke around host.]

System like straight man rejected the idea without even thinking about it.

"Then can I exchange it with a katana made of proto-adamantium."

[Ummm, No but you can exchange it with True Adamantium host.]

"Okay then make me a True Adamantium Katana just like Giyu Tomioka."

[Deal then, Now do you want to travel to MAIRIMASHITA! Iruma-kun world Host.]

"Yes." I replied cheerfully, suddenly I feel dizzy and slowly I lost consciousness.

As he passed away his soul drifted into space and into the light where he woke up crying as a baby in the hands of a Asian women and as he struggled to control his new baby body he hears somebody speak in Japanese.

"Congratulations madem it's a healthy baby boy, do you have a name ready for your new son." the doctor asks Mu Chen's new mother.

(Because he was planning to visit Japan, he knows Japanese language perfectly.)

The mother looking exhausted from the labor just smiles while holding her baby and says .

"Yes me and my husband have decided to name him Suzuki Iruma."

Now hearing that name Mu Chen who's name is now Iruma was quite shocked inside.

'What the fuck I killed that kind kid.' He said while feeling little sad about Iruma.

[You don't have to worry about that host! Because in this alternative world Iruma was meant to die as a newborn.]

'What, then who will Sullivan adopt in this world.'

[Sullivan will adopt an demon in this alternative world, but now system have changed something! So Sullivan will adopt you don't worry.]

[Lastly goodbye host, but don't worry! I will leave a sub system as a gift for you which will help you in my absence.]

'Why are you in such a hurry to leave brother system.'

[System have many work's to do host, So see you soon host and reach 100% of ten times Giyu Tomioka template quickly to get another template host.]

'Goodbye then brother system.'

And with these thoughts Mu Chen or Iruma soon fell asleep in his mother arms peacefully.
