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

Chapter 137   A Challenge from the Most Terrifying

A few days after Ars and Hades-chan’s wedding settled down.

I, Kakyu, who was preparing for the final showdown, suddenly barged into the domain of the God of Magic, who was leisurely dedicating himself to magic research in the heavens, to seek his cooperation in the preparations.

By the way, Elsa was originally supposed to accompany me on this trip to the heavens, but for some reason, even Chibisuke, who had taken an interest in my actions, tagged along.

“I think I need to visit my hometown occasionally too, you know. Grandpa would think so too, right?”

“W-what is with this overbearing attitude from an angel… Calling me grandpa the God of Magic, Oldemir…”

“Grandpa is grandpa, right? I love Grandpa Oldemir, you know?”

“M-mmph!! I-is that so… Alright, I shall permit you to call me grandpa.”

And that’s how it went.

The reason this Chibisuke can be so bold with his superior is apparently because she is promised a promotion to the highest-ranking angel in the department that oversees the lower world.

It’s a position higher than the head angel who manages the miscellaneous angels, and in terms of the earthly dimension, it’s equivalent to a promotion to the rank of Seraphim.

She is clearly on the fast track to becoming an elite.

According to Preanis, the head angel, this promotion was decided based on the combined judgment of the gods, recognizing her achievements in guiding the hero who saved the world and improving the future, as well as her various accomplishments in the lower world.

Well, it’s not immediate, but a Seraphim in the standards of the heavens in this world is just one rank below a lower-tier god.

It’s an incredible promotion.

Incidentally, the one who pushed hardest for this Chibisuke’s promotion was none other than the God of Magic, Oldemir himself, and his reaction upon learning of the countless miracles Chibisuke worked so hard to achieve was like that of a grandparent admiring the success of their grandchild.

Oldemir, the old man, has a habit of thinking things through logically. Because of this, he’s always been interested in Chibisuke, who solves problems by bypassing logic and relying on momentum and intuition. Over time, as he observed Chibisuke, he grew fond of her, and now treats her like a grandchild.

Incidentally, Preanis, the source of this information, had asked me not to mention it to the person involved, so it seems to be a well-known story in the heavens.

Because of this, when I brought Chibisuke along while seeking the God of Magic’s cooperation, I was warmly welcomed by the old man who couldn’t get enough of his “grandchild.”

“So, Demon God of another realm. While the design of this other space might indeed prevent harm to the lower world, if energies exceeding the anticipated output collide…”

“Yeah, I understand. I’m aware of that. And as I’ve said many times, call me Kakyu, not Demon God. I’m not a being of such high virtue to be called a god or anything.”

Perhaps to avoid intimidating my wife, Elsa, or perhaps to pat Chibisuke on the head himself, the old man had shrunk his grand stature down to human size and offered me advice.

The old man’s concern was valid. The fact that he immediately noticed the dangers of this design upon hearing about it shows that, as a god overseeing magic, he’s quite sharp. But this time, that’s fine.

As long as there’s no harm to the human world, it doesn’t matter if the other space blows up or whatever.

“As you know, Oldemir, the purpose of Ars’s birth is to eliminate foreign objects that came to this world from another realm. No, more accurately, it’s for the world to confirm that this elimination function works properly.”

“Indeed. The will of the world and the will of the gods are separate, but we are considering the same thing.”

In that case, the discussion is simple. However, if the old man hasn’t realized it by now, it shows that while he has a deep understanding of magic, his thinking is quite rigid regarding other matters.

In fact, the fragility of this other space is precisely to account for the elimination of such foreign objects.

“In that case, this design is fine. Rather, it needs to be somewhat fragile to the other space. Don’t you agree?”

“What are you talking about? If the other space breaks down unable to withstand the battle with the hero, you would be… No, wait! I see!!”

It seems he finally understood.

Well, that’s exactly it.

If Ars, who has grown immensely over the past five years, fights seriously, it’s well within expectations that the space will be blown to bits with energy beyond what was anticipated.

The real issue was how to protect the lower world from the aftermath, but that problem is being solved by the other space designed in collaboration with the God of Magic. The rest is simply a matter of how hard I, Kakyu, strive to survive.

After all, Ars is now so strong that even I can’t afford to be careless. Although he can’t power up like a cheat using the combined strength of humanity without a mission like saving the world, he can still produce output comparable to that time on his own.

I raised him myself, but he has become an incredible man.

“Well, that’s why I’m counting on you, Oldemir.”

“I see, hearing the reason, there’s no better solution. …Alright, I owe you for watching over this angel on her journey. As thanks, I will take on this task with full responsibility.”

That’s how it is.

What a tsundere old man.

It’s true I watched over Chibisuke, and it’s not a lie that he’s doing this as thanks. But his true feelings are different.

This old man is simply a kind person.

He probably feels affection for me, who understands magic as deeply as he does and can be considered a friend with whom he can compete and improve.

Even without using the Devil Eye to read his emotions, even Chibisuke can see this.

“I really do love Grandpa. There, there.”

“Hm!? I-I don’t feel bad, but this undermines my position…”

The tsundere old man is saying something.

After a few months of discussions with the God of Magic in the heavens, the special space was finally completed. To invite the main character to this space, I sent a letter to Ars, who was enjoying a newlywed life full of love in the lower world.

If I were to give it a title, let’s see…

A Challenge from the Most Terrifying, perhaps.
