I was Caught up in a Hero Summoning, but that World is at Peace

The monster was born in a volcano in a corner of the Demon Realm. It was born out of the burning lava.

It had long hair, two huge horns…… and red eyes that held no reason. The monster obliterated the volcano in which it was born and its surroundings, and slowly began to walk through the Demon Realm.

The only thing the monster had was the urge to destroy, and everything in its sight was an object of destruction.

Whether it's the land of the Demon Realm or the creatures living there, it attacked anything and destroyed everything. Of course, it isn't that the Demons didn't try to resist the monster.

The Demon Realm of that time was a warring era, and there were many skilled Demons everywhere. Naturally, they thought of defeating this monster.

However…… The monster was overwhelmingly powerful. Neither physical attacks nor magic can penetrate its tough skin. Neither a strong shield nor Defensive Magic could block the monster's attack.

Not even a single blade of greenery remained after the monster's steps, and it continued to walk through the Demon Realm, destroying everything in its path.

The damage caused by the monster spread to one-third of the Demon Realm, and when the monster became known and feared as the "Red Demon Beast", it arrived near the center of the Demon Realm.

In that place stands a small house inhabited by two Demons. Naturally, everything in sight is an object of destruction for the monster, and the house was no exception, and it was supposed to destroy it and move on.

[……Ein. Take your distance, it's dangerous.]

[Y- Yes.]

That is, if it wasn't for Kuromueina, who was later called the Strongest in the Demon Realm, who was living there…… The monster was indeed strong. With its excessive power, it attacked Kuromueina and managed to inflict a faint wound on her.

Yes, a faint wound…… That was all it could manage to do.

[……You have great power. Hmmm, I'm sure she had a hand in this. Haahhh, I wonder what she's planning…… Being pushed around by her like that, you've got it rough.]

Seeing the power of the clearly abnormal monster, she could tell that this monster was tampered with by the other half of his body who she had yet to meet…… the God of Creation, Kuromueina let out a sigh and tampered with the being of the monster herself.

She sealed off its powerful destructive impulse and arranged its appearance to be somewhat similar to herself and Ein.

[……Gurururu.]

[Unnn. You certainly are quite lively. Moreover, due to the effect of sealing its destructive impulse, it will not attack…… W- Well, it seems to be a little scared…… but I guess when it comes to matters like that, I could just teach it.]

Since her half-body is involved, Kuromueina decided to take custody of the monster…… and gave it…… gave her the name "Megiddo".

The monster…… Megiddo was obedient to Kuromueina. She was a strong being who had defeated itself. She learned from Kuromueina's teachings and acquired knowledge.

In the process, she learned the joy of training herself and competing with others. At the same time…… Even though Kuromueina's seal was in place, she resented the destructive impulse that still remained in her being. She hated herself for destroying one-third of the Demon Realm.

She came to hate her monstrous self who did not enjoy fighting, didn't compete with others, didn't give her opponents a chance to grow, and simply laid waste and destroyed everything.

Somewhere along the way, Megiddo herself put seals on her body to seal away her true form.

However, Megiddo's destructive impulse still has not disappeared. Even though it's sealed, that impulse continues to sleep in the depths of her body.

That is why Megiddo hated her true form. For when she returns to her true form, she could also feel the presence of that destructive impulse still exists deep within her……

After some conversation with her, Megiddo-san deeply exhaled, as if to switch her mind off the topic.

[……Well, that's about it. So, going back to the main topic…… I somehow managed to do something about that destructive impulse, but dealing with it like this still has its troublesome parts to it. It won't listen to me at all.]

[You can think of it as the gorilla having a rabid dog as a pet on her belly. And now, Megiddo-san wants Kaito-san to train that mad dog……]

[Well, something like that.]

[……I don't really understand what's going on though.]

I understand that Megiddo-san hates that destructive impulse and wants to control it somehow. However, I don't understand the point of having me do that.

How am I supposed to control Megiddo-san's destructive impulse?

[Long story short, I want you to crush my destructive impulse and have it submit to you.]

[……Explaining it like that wouldn't make him understand though…… Errr, Kaito-san. There is a special magic called "Mind Competition". In short, it's like a mental battle that can be done with mutual consent, and Megiddo-san's destructive impulse…… You can think of it as a kind of emotion. Megiddo-san wants you to defeat her destructive impulse through that.]

[I kinda get it, but I also kinda don't.]

[Incidentally, Megiddo-san had also asked me and Kuro-san this and we tried it out…… but that destructive impulse doesn't admit defeat at all. No matter how many times we beat it up, it seemed to think that it would win next time……]

Looking at Alice, who astoundedly said that with a sigh, I thought that even if it was Megiddo-san's destructive impulse, in the end, it was still part of Megiddo-san's emotions. So, I had this impression that this impulse's personality was similar to Megiddo-san's.

[……And now, here's where you come in, Kaito. I'd say Kaito's mentality is one of the best I've ever known. I thought that if it's you, you could probably do something about it.]

[……I- I see.]

I understand the situation now. I understand but…… I'd like to hear a little more detail about that mental battle.

<Afterword>

? ? ? : [The serious development…… isn't here just like usual. That person…… and that title…… Oya, this is……]
