I have a hero simulator

"I see. That scared me. By the way, why is Buu-sama in my room? Could it be that he's been watching over me until now... I'm so touched!"

"No. You're being suspicious. Buu was just chatting with me."

"Really? I was just overthinking it... Hey! Great Sage, why are you talking now? And it seems like you're pretty close to Buu!"

Rimuru started to complain, but the voice did not answer him further.

"What's going on? Am I really overthinking it?"

"No, there's no time for that now. How are they all doing?"

"What happened to the others?"

"What's the situation now?"

Questions arise one after another.

But soon someone came to solve the problem on behalf of the great sage.

"What are you talking about, Rimuru? Is everyone okay? Nothing has changed here. Did you have a nightmare?"

Shen Yuan said in a teasing manner.

"Eh? What do you mean, the Jura Demon Kingdom wasn't attacked by humans..."

Rimuru quickly jumped out of bed and ran towards the door. When he reached the door and looked outside at the thriving green leaves and flowers, which were exactly the same as before he left, the whole slime was stunned.

"No, isn't this place destroyed?"

"Besides, I saw them being killed with my own eyes!"

Rimuru described the situation incoherently and excitedly, but it was as if he had just woken up from a dream and found that nothing around him had changed at all.

Was it really just a dream?

It is true that he can evolve into a "True Demon Lord", but why are his memories and the scenes he saw completely different?

As if to confirm something, Rimuru went to ask Shuna, the goblins, and the dwarf brothers, but they all replied, "Did Rimuru-sama have a nightmare? The Jura Demon Kingdom has never been attacked by humans. Why do you say that?"

Suddenly, Rimuru began to doubt his life...

By the way, why not just ask the great sage!

"Great Sage, did everyone from the Jura Demon Kingdom die before?"

Not dead.

"Did I resurrect them?"

"No."

"Has the human army ever been here?"

"No."

"Did I really have a dream? Then is it true that I evolved into an awakened demon king?"

"Yes."

"Great Sage, you won't lie to me, will you?"

Rimuru was a little confused, and began to doubt whether there was something wrong with his memory.

No. I answered your question truthfully.

"Great Sage, are you unhappy with me?"

Your Illusion.

"I think you've become quite a bit more arrogant since I evolved."

No, it should be said that she is tsundere.

After the Great Sage evolved into the King of Wisdom Raphael, he gained self-awareness and began to become sinister.

"So what happened? What is real and what is fake?"

Just as Rimuru was scratching his head.

"Oh! My master, you're awake!"

A familiar voice came.

In the darkness, a man with red and gold highlights mixed in with his black hair appeared.

He is the 'Original Black', or "Diablo".

The one who named him was Rimuru.

To be precise, it was Rimuru during Raphael's time. At Shen Yuan's suggestion, Raphael named him "Black".

Rimuru was unaware of this because Shen Yuan made the decision for him.

Raphael also knew that this would be helpful to Rimuru, so he did not refuse.

"What's wrong with you?"

Diablo stared at the dazed Rimuru, his golden and red eyes flashing with an eerie light.

He bowed gracefully, dressed in the finest gentleman's suit, dressed like a butler.

Demoted from ruler to servant.

However, his unruly and domineering aura increased instead of decreasing.

"Uh, who are you?"

"What! You actually forgot about me? I am Diablo, the high-ranking demon general you summoned and named..."

The devil pulled his handsome face and revealed a sad expression.

"No, why don't I have any memory of this?"

Rimuru racked his brains but couldn't figure out what had happened, so he began to ask the great sage.

《Answer: The individual "Diablo" was originally a high-ranking demon general. As his master evolved, his energy increased significantly, so he also evolved.》

"I remember now. I did summon a demon before I fell asleep!"

Soon, Rimuru recalled the scene when he fought with the human army, and then looked at Shen Yuan who was laughing at the side with a bad look.

"Great! Buu, you really did something to me!"

Rimuru said angrily: "Tell me the truth quickly! What is going on!"

"Look how childish you are."

"Lord Buu, Lord Rimuru has been teased so pitifully. You should tell him the truth."

Even the female demon servant beside her couldn't bear to watch it anymore and couldn't help but speak.

"Alright. Then, let's have a meeting while we're at it."

Shen Yuan looked at the angry Rimuru and stopped teasing him. Instead, he announced his next big plan.

Next.

Lord Buu will announce a plan——

[Conversation between humans and demons and a battle between demons and celestial beings!]

......

The newly born Demonic Federation, Jura Tempest.

Central City, on the street.

"Long time no see, Rimuru. I heard you became a Demon King too, right?"

The Dwarf King Gazel led the Sky-Soaring Knights and descended into the newly born monster city.

"King Gazel!"

Rimuru looked at the newcomers in surprise. Besides them, there was also an envoy from a human country.

"It was you guys who kidnapped my daughter..."

As if there was a murderous aura coming, Rimuru looked quickly and found a middle-aged human male.

“Rimuru-sama, this is the messenger sent by the Magic Dynasty—”

The Goblin King leaned close to Rimuru's ear and whispered, "This stinky-faced daughter-obsessed guy, his daughter is Miss Irene, Miss Jing's companion. We've entertained them before."

"I see!"

Rimuru finally understood.

After that reception, the trio of human adventurers realized that these monsters were not bad guys.

That female adventurer refused to leave the Monster City and has been living there as a foreigner, eating and drinking for free. Thanks to her status as Rimuru's friend, no monsters are hostile to them.

When the girl's father heard about this, he thought that his daughter was controlled by the Demon King. It happened that the Demon Federation was established, and the Magic Dynasty also needed to send people to investigate. He volunteered and rushed over to find out what was going on.

"Wait, Dad!? Why are you here?!"

The human female adventurer Irene looked at her father who appeared on the street in astonishment, and ran over with an embarrassed look on her face, asking him to stop embarrassing himself.

Her old father looked at her dotingly, his face full of love.

"Um, it's all a misunderstanding..."

Irene hurriedly explained, ending the farce.

Then, under the arrangement of the Demon Messenger, people entered the throne hall one after another, including the Messenger of the Beast Kingdom, the Human Duke, the Dwarf Hero King, and so on.

In this serious atmosphere, the meeting began.

The main issues they discussed were the current situation of the Jura Great Forest, the situation of the human nations, and the Demon King's Banquet ending with Clayman's death.

It's easy to get sleepy in meetings.

The commentator from the Four Heavenly Kings, Shuna, spoke on behalf of Demon Lord Buu, who fell asleep.

"So, what is the truth?!"

Rimuru approached Shen Yuan and asked secretly in a low voice.

"Uh, this."

Shen Yuan opened his eyes and looked at Rimuru, the silver-blue-haired lolita who was approaching him, then said disapprovingly, "Raphael, didn't you explain to him?"

《No. You said that you wouldn’t give a full answer unless Rimuru asked about the cause and process of the matter.》

The voice of the great sage came in Rimuru's mind, but Shen Yuan seemed to be able to hear it and replied: I see.

However, this action left Rimuru stunned on the spot.

"So, you guys...are in collusion!"

Rimuru felt like he was being cheated and felt like crying.

《Notice. All of this was planned by the individual "Buu" Demon King. It has nothing to do with me. Please be aware of this.》

Raphael, the King of Wisdom, immediately passed the blame on to others.

So she began to tell the whole process verbatim, including how Rimuru evolved into the "Awakened Demon King" and some of the immoral things that Demon King Buu did.

then.

Faced with the bewildered Rimuru, Shen Yuan confessed everything he had done.

"Ugh... Damn it! That's too much!"

I originally thought that Rimuru would be very angry and yell, but unexpectedly he puffed up his cheeks in grievance, showing a very cute and adorable posture.

It felt like a crying little loli who was about to be toyed with.

"This is all to help you evolve faster. Okay, let's get down to business."

After Lord Buu (Shen Yuan) calmed Rimuru down, there was a commotion outside.

"Wa hahaha!"

A burst of hearty laughter was heard, and then a muscular blond man with a bare upper body, the human form of the Storm Dragon Veldora, walked in.

When Rimuru evolved and awakened the Demon King not long ago, the King of Wisdom released the awakened Storm Dragon Veldora and used his new ability to give him a body.

then.
