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

Chapter 131   Three pieces of advice, a guide to victory.

Just as all the actors were assembled and the showdown, stemming from a long-standing grudge, was about to unfold—

Seizing the initiative, the Black Knight Jokyu, seemingly planning to unleash a powerful attack, raised the enormous greatsword in his right hand ——

“First! The Demon King’s weakness is his stamina! Though the Demon King is strong, he has been pushing his abilities to the extreme using a certain man’s secret technique, making him unable to withstand long battles!”

“What…?”

“Huh?”

—— Just as he raised the sword, the sudden revelation of the Demon King’s weakness by one of the Three Demon Generals caused the hero’s party to freeze in place.

And understandably so.

They had braced themselves for a major attack from the enemy, only to have him start babbling incomprehensibly.

Whether this revelation of weaknesses was true or not, it was only natural that they would be somewhat curious.

In fact, the hero, Ars, seemed intent on prolonging the conversation to extract any information he could, standing firm in a defensive posture without attacking.

Moreover, Saintess Isha, being of royal blood and highly sensitive to lies, utilized her special magic to ascertain the truth. She confirmed that the enemy’s words didn’t seem deceitful.

The saintess gave a small nod to the hero, signaling that the statement was indeed true.

Even Sword Saint Ein, who bore an intense grudge against the Black Knight, was now watching the events unfold, eager to glean any information about their ultimate target, the Demon King.

Incidentally, Mermel, who was munching on choco marshmallows, was so shocked that she dropped the bag of assorted sweets she was holding in her tiny hands.

Of course, a dumbfounded expression didn’t suit an elite angel, so she hurriedly picked up the bag and adjusted her sunglasses, but it was already too late.

“Huh?” she muttered, almost stumbling, which did not escape the notice of Black Knight Jokyu.

Under his jet-black helmet, a low-class demon smiled slyly, having successfully caught them off guard.

“What, what did you say? Hey Ars, did you hear that? It seems what the Black Knight said is true.”

And then began Gaius’s blatantly scripted reading.

Even though it was according to plan, his acting was so terrible that even as a low-class demon, one couldn’t help but think it was too poorly done, though pointing it out now was out of the question.

Looking around at the hero’s party, and to cover up his subordinate’s poor acting, he continued his advice in a loud voice.

“Second! The captive Demon Princess Hades Lucifer cannot be freed by killing the Demon King! Because I have set a trap that will imprison the Demon Princess in another dimension if the Demon King dies! Oh, what a tragedy!”

Everyone present felt an overwhelming urge to shout, “You don’t get to say that!” but managed to suppress it without voicing it.

Not only because they were in the middle of a battle and the information was crucial, but also because it seemed there was more to this story.

“And moreover… Hero Ars. Having overcome countless trials with your companions and traveled the world, how does this war appear to your eyes?”

The Black Knight Jokyu posed the question.

The demons were the first to invade the human world.

In this war, the demons were the enemy and an undeniable threat.

Yet, strangely, within this Demon King’s castle, while there were several presences that seemed to be demons, none of them felt hostile. Instead, it felt like they were merely observing the situation.

Moreover, if the demons were inherently evil, then what about Hades Lucilfer, the Demon King’s daughter? Despite being the Demon King’s daughter, she was never considered “evil” by her companions or by humanity.

And the Demon King, who, despite the relentless advance of the hero, neither fled nor attacked, waiting in the deepest part of the castle as if saying, “I’m waiting for you to kill me.”

Finally, the Black Knight Jokyu, who claimed that killing the Demon King would not truly free the Demon Princess Hades.

It presented a contradiction, not favoring one side but implying that solving the problem required saving both, much like a question posed by his father, Kakyu.

Realizing this, Ars stiffened, understanding the true meaning of this war, and a bead of sweat trickled down his forehead.

“What are you hesitating for? Aren’t you the world’s strongest hero who saves everything important? Hey, Hero Ars.”

“No way… Could it be that this war…?”

Upon realizing the truth, Hero Ars shifted his focus away from the Black Knight and towards the direction where the Demon King awaited deep within the castle.

The Black Knight, satisfied with the perfect answer to his question, finally revealed the truth.

“Yes, that’s right. The Demon King plans to take all the evil in the Demon Realm with him and be killed by you.”

Seriously, it’s unbearable.

That doting father, the Demon King.

The Black Knight Jokyu, grumbling about how troublesome things were, finally readied the greatsword he held as a weapon.

It seemed the discussion had come to an end.

“And lastly, the third piece of advice. —— Understand all of this and utterly crush the Demon King’s will!! With overwhelming power, blow away all problems!! What does the Demon King’s responsibility matter, or the Demon Realm? Isn’t that right, Ars? There’s no way you could be defeated by such things!!!!”

The reason the Demon King must perish along with the Demon Realm is to take responsibility for starting this war that sacrificed many demon lives.

If the leader at the pinnacle of the Demon Realm sacrifices the Demon Realm for his daughter’s happiness, he naturally cannot escape that responsibility.

Otherwise, the order among the demons would collapse, and even those known as the moderate faction would break free from the Demon King’s family’s control and turn their fangs on the human world.

What would humanity do then?

They were already pushed to the brink of extinction by the radicals, so could they survive facing the rational and intelligent moderates who follow the Demon King?

Could they fight and win against the entire Demon Realm?

No, one would have to say it’s impossible.

In that case, true hell would begin.

…Yes, that would have been the case.

But ultimately, such thoughts underestimated the power of Hero Ars, mere prattle of the defeated.

The most terrifying low-class demon, who came from another world by chance.

In front of the world’s strongest hero, raised by such a demon, the malice of the Demon Realm was no more than dust.

Therefore, now is the time to prove it.

Even if the opponent is the Demon King, made formidable by some mysterious man’s hand, he is no match for the strongest hero.

Without the Demon Realm baring its fangs, with this strength and the bonds with his companions, all enemies would be silenced.

Hero Ars will rescue the Demon Princess Hades Lucifer, and there is a future where even the Demon King survives to bless them both.

“Go, Ars!! With your power, save your lover and the entire Demon Realm!!”

“…Yes!! Father!!”

As the Black Knight Jokyu, or rather, Kakyu raised the greatsword above his head, a red-black flash of light burst through the ceiling of the Demon King’s castle with tremendous force, the rising magical current guiding the heroes to the final battleground.

“Father, huh. …Good grief. Maybe I went a little overboard. No wonder it got revealed.”

Muttering as he watched his son and his companions being transported to the final battleground, the low-class demon activated the magical camera and, incorrigibly, resumed collecting family videos…
