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

Chapter 130   The Farce of Fate begins

The enormous transfer gate, though cleverly concealed, could no longer be hidden once recognized as “there.”

The otherworldly door to the demon realm distorted space into a semi-circle, grandly seated upon the earth.

The portal, about a kilometer in diameter, shimmered like a mirage, faintly revealing the demon realm beyond.

In this fearsome and supernatural space, humans advanced without showing fear.

In reality, none were devoid of fear, but they pressed on regardless.

Some marched for the lives they had lost.

Others for the pride they could not afford to lose.

They became walls, shields, and sacrifices against formidable foes, protecting the hero for the final blow.

With the hero as their standard, humanity’s combined forces continued their advance.

At last, they set their sights on the majestic Demon King’s Castle and clashed with the main demon army swarming the demon realm.

◇

“I knew it was coming, but this is something else. It’s finally here, huh, Mr. Demon King?”

“Indeed. I am well aware.”

Here I am, the black knight, or rather, the lower-class demon Kaku, preparing for the final battle at the Demon King’s castle.

Humanity has finally made its move and entered the demon realm. From the castle, we can see the grand spectacle below, a fierce battle with both sides throwing everything they’ve got into it.

The clash of these massive armies, pouring in all their resources, seems like a world-ending Ragnarok. It’s almost like a beautiful, mystical painting, though it’s inappropriate to think so.

By the way, it took humanity about five days to reach here. Fortunately for them, even the Undead’s Four Heavenly Kings and the highest-ranking vampire, the Immortal King, couldn’t stand against the hero’s party.

As soon as they engaged, Isha’s holy barrier immobilized them, Sword Saint Ein severed their heads and limbs with his skill, Gaius shattered their heads with a single blow, and Chibisuke’s flames left nothing but ashes.

It happened so quickly that Hero Ars didn’t even have a chance to act. These guys are amazing—completely different from when they fought Hecatoncheir, another member of the Four Heavenly Kings, in the past.

To be honest, Gaius has become stronger because I equipped him with magical gear to assist Ars. But the rest of the team reached this level purely through their own efforts, driven by extraordinary determination and perseverance.

Sword Saint Ein is especially formidable. If he were to fight a mid-level hero from the past, he could probably decapitate them with a single strike before they could even power up with their Brave Engine.

Heroes’ strength comes largely from their tenacity, their fighting power fueled by their emotions, and their limitless energy, so it’s not simply a matter of who’s stronger. If a fight drags on, heroes gain an unstoppable power that mere sword skills can’t match.

Heroes embody the idea that the hero always wins in the end.

Nevertheless, I can see Ein swiftly taking down past heroes before they even have a chance to fight back.

Ein’s ruthlessness likely stems from seeing his kidnapped friend Hades in himself. He also feels a profound sense of duty to protect his master and love interest, Saint Isha. Right now, I can almost hear his heart’s voice saying, “I will not forgive the black knight.”

As we prepare for this final battle, the determination and skill of the hero’s party stand as a formidable challenge, one that even the forces of the demon realm must respect.

“Truly ominous, almost mad, I must say.”

“My, oh my, what a fearsome young man.”

“Uh oh, this feels just right for a fight, but it’s going to be quite challenging.”

“Hmph. That man who’s known as the Sword Saint, if it weren’t for your son, the hero, he emits such a pleasant killing intent that I might even consider him as a prospective son-in-law for my daughter. Yes, he’s truly a splendid talent!”

For a human without extraordinary powers, to be recognized by the Demon King solely for his swordsmanship—well done, Sword Saint Ein.

However, in the back, the role of the imprisoned princess, Hades-chan, seems dissatisfied, saying things like, “There’s no way I’d fancy any man other than Ars!” or “Huh?! Hey! Saint with the wooden board and the mysterious cat ears! You just gave Ars a look of sexual interest, didn’t you?! I’ll kill you!”

Probably, even if Ars weren’t here, she wouldn’t have found anyone to her liking.

“…Alright! Well then, I’m going now.”

“I’m counting on you. There shouldn’t be any issues with you, but humanity is coming to kill. Don’t let your guard down.”

“Sure, sure.”

While humanity’s forces hold off the pitiful main demon army intentionally assembled by the Demon King, it seems my son and his group have finally reached the Demon King’s castle.

If I don’t join in soon, there’s a tragic possibility that even the moderate demon factions, not intended for slaughter, will die in the castle.

Therefore, Black Knight Jyoku is finally setting out.

The Demon King old man may not know this, but unlike the demons of this world, the demons of Hell can resurrect with just their soul remaining even if their body is destroyed.

In other words, they do not die.

I can’t provide evidence since becoming a demon from the time of Hell, I haven’t been killed once, but the other demons of the same kind are resurrected with only half their magic.

There’s no intention of dying, and it’s a future where it’s impossible for me to be killed by my son and the others, who are still developing, but in terms of survival, it’s a no-risk situation.

Such as magic, you should also store and practice it.

With such a fragment of pressure, with a relaxed atmosphere, I lightly transfer to the entrance hall of the Demon King’s castle, which can also be called the entrance, waiting for my son.

Now, how do they plan to overcome my efforts for them?

I’m really looking forward to it.

Thus, the heavy yet magnificent door of the Demon King’s castle slowly opens.

“I kept you waiting, Black Knight Jyoku. We’ve come to reclaim Hades by force.”

“Heh, it wouldn’t be interesting otherwise.”

────The hero Ars, who has grown to be recognized as a savior of the world, along with his comrades, appeared.

Now then.

Let’s witness the uproarious farce spun by the peculiar lower-class demon.

“…I feel like I’ve been dragged into something incredibly ridiculous.”

Hey, Chibisuke, keep quiet.

“Hmph!”

“Eek!? What are you… munch munch”

Immediately, prompted by my signal, Gaius throws a specially made chocolate marshmallow into Chibisuke’s mouth and hands over a snack set to those tiny hands.

Phew, that was close.

It was good to entrust the trump card to Gaius just in case of emergency.

Chibisuke is not someone to be underestimated.

Let her munch on that chocolate marshmallow here and observe until it’s over.
