Reincarnated Devil’s Strongest Hero Training Plan ~The baby he picked up has grown up so well that his father is confused~

Chapter 120   The most low-class demon moves

In the heart of the demon world, where violence and magic intertwine, stands the majestic Demon King’s castle.

Within the audience chamber, a symbol of power and death.

In the silence of the room, the hard sound of footsteps, clunk, clunk, clunk... echoed from an unknown direction.

The Demon King, seated on his throne, looked towards the source of the sound and, seeing a black-haired, black-eyed man, realized, “So, it’s come to this…” He understood that the time had finally arrived.

“Your Majesty, let me handle this…”

“No need. Even if you or I struggle, there’s nothing we can do against that man. As the Demon King’s foremost vassal, stand firm and proud.”

“Yes, Your Majesty!”

The Demon King’s first vassal.

The attendant, dressed like a clown, ashamed of his overreach, stepped back.

Yet, his feelings were understandable.

The opponent far surpassed, no, transcended the power of the Demon King he served… It was a being one could call a demon god.

The power he felt was greater than any hero he had ever encountered, and even more immense than any gods that might exist in the heavenly realm.

When faced with such a creature approaching naturally, it was only natural to instinctively move to shield his master.

The name of the monster who advanced leisurely before the top two of the demon world was…

“Yo! Long time no see, , old man. Let’s make a deal, you and me.”

The demon from another world, Kakyu, had arrived.

◇

“…So, how’s the power settling in?”

“Excellent! Excellent! Excellent! What incredible power! Is this the power of a demon god, Kakyu? Truly, it’s a pity that a man like you isn’t my vassal!”

Hold on, I already heard that in the tavern.

This guy just never gives up.

“How many times are you going to say that, old man? This is getting old!”

“Guwaaaah-ha-ha-ha-ha! Indeed, Kakyu! Ha-ha-ha-ha!”

Is he really okay?

He probably isn’t listening to a word I’m saying.

No doubt about it.

Well, he seems to be having fun, so I’ll leave him be.

The reason I invaded this demon world is simple: to carry out a grand scheme across worlds, made possible because the Demon King’s and my interests aligned.

To explain further:

I pushed Ars too hard, and as a result, he elevated his hero’s power to an extraordinary level.

How extraordinary, you ask? Well, to the point where he could single-handedly invade the demon world, defeat the Demon King’s forces, and return home unscathed.

In other words, if left unchecked, he’d be able to one-punch the Demon King with his golden power.

The fight would be so one-sided that I wouldn’t be able to achieve my goals, so I decided to lend a hand.

Now, you might be wondering, what exactly was the old man’s goal? Simply put, it was to perform a grand cleanup of the demon world.

There are still demons who see humans as mere food or who wish to enslave and oppress them.

To eliminate these troublesome elements, he planned to invade the human world and “intentionally lose to the hero,” thereby taking himself out along with them.

Why did he come to such a decision?

All of this was for the happiness of his only daughter, Hades Lucifer.

Originally, it seems the old man was grooming Hades-chan to become the next Demon King, and there wouldn’t have been a need for him to make such choices if Hades-chan hadn’t run away from the castle one day and met Ars.

Despite being expected to become the next Demon King, Hades-chan fell in love with a human, the very strongest human who once stood against and ultimately surpassed the previous Demon King.

Now, the old man was faced with two choices.

One was to fulfill his duty as the Demon King and dispose of Hades-chan.

The other was to abandon his responsibility as the Demon King and side with the humans.

In essence, it boiled down to choosing between ruling the demon world or choosing his family.

The old man was torn.

Naturally.

If he didn’t fulfill his duty as the Demon King, the demon world would descend into chaos, and even the old man wouldn’t be able to control it. Ultimately, this would likely lead to a full-scale war between the demon and human worlds.

So, what was to be done?

…In the end, the conclusion reached was a suicidal attack.

While maintaining the pretense of being hostile to humans and disposing of Hades-chan, the old man would provoke the hero as the Demon King, inciting the entire demon race to oppose the humans, thereby choosing to destroy himself along with them.

In doing so, it seems the old man chose to fulfill the responsibility of the Demon King while maintaining the order of the demon world and securing Hades-chan’s future.

Truly commendable, old man.

He’s already assumed he’s dead, planning to leave the role of the next Demon King to his wife, the queen, and his decision-making is swift.

Originally, this plan should have gone smoothly.

There was no prospect of the old man defeating Ars after his awakening.

However, things didn’t go as planned.

Because there’s someone here who’s put a stop to it all.

“We made a promise at the tavern, remember? When things get absolutely hopeless, I’ll come to your aid no matter what the situation.”

“Gwahahaha! Of course! After being asked to lend a hand, I couldn’t just die without saying goodbye to my drinking buddy, could I? I shouted it out loud in this castle! I believed you’d come!”

“Oh, I heard you loud and clear.”

The one who’s putting a stop to it all?

That’s obvious. There’s no one else but the drinking buddy, Kakyu-san.

But the old man doesn’t understand.

What happens if he dies in this suicidal attack?

While the queen, being an adult, might understand the Demon King’s intentions, what about Hades-chan left behind?

And what about Ars, who couldn’t save Hades-chan?

So, for the sake of my son and the old man’s daughter, both fathers have risen to the occasion.

The Demon King’s army may still provoke the human world, but the endgame is different.

Now that I’m here, there’s no way we’ll end up with a shitty bad ending where the old man dies.

Whether human or demon, deceiving others is the devil’s specialty.

With my worldwide deception, as an Earthling and a low-class demon from Hell, I’ll brilliantly deceive them all.
