Boring Reality

「What is the meaning of this?」

I muttered quietly while looking down at the minced idiot prince(Gilbert). It was such an unexpected situation. According to Rose, this guy should've received a gifted education of martial arts from a young age. Though he never used magic again due to certain incidents, talent-wise, he was comparable to the leading magician of court mages. I had never expected that he would lose against that weak small fry who hid his true strength.

「That's why I said using THAT is overkill to that monkey.」

Asta, who stood behind me heaved a sigh as she repeated the same remark for the Nth time.

「So I made a mistake to judge someone's real strength…」

「Master, you're underestimating yourself way too much. Those inferior creatures(human) are far weaker, and brittle than you expect. So weak to the point that even that weak small fry like that can kill them so easily.」

Underestimation, is it. And humans are weak. I failed to see that. For once… After spending more than one hundred thousand years in that easy dungeon, never once fighting against another human, I ended up unable to properly measure human strength.

But, I see… If it was my misjudgement――

「Could it be that balloon-like undead is actually a powerful being?」

「I've no idea which strength value you're referring to. That undead is small fry according to our group's standard. But, according to the normal standard of this world, that undead is the most powerful transcendent in this world aside from us. Not to mention that even us are only small fries in your evaluation, Master. We're literally equal to the creature you call as goblin around the forest.」

I see now. I felt something was off. Why did a giant organization such as Babel and Hunter Guild readily obey my orders?

――Because they understood that they could never win against me.

Now, everything is finally clear for me. Does that mean the pervert who only wore underwear and small fry dragon with three heads were powerful foes?

If that was really the case. I've already――

「Asta, do you think I can fight with my everything after this?」

Asta averted her gaze, and shook her head lightly.

「…I see.」

I looked down at my feet.

「HAHAHA! SO I'M SOMEONE WITH FEW SCREWS LOOSE IN HIS HEAD ALL ALONG, RIGHT!?」(ED: Finally!)

What I wished should be a slow life, right? Since that was the case, what is this empty feeling in my heart?

「Asta, now I understand why you retorted all those times.」

「I see.」

Asta nodded lightly as she replied to me, her figure then vanished.

「I'll take responsibility for this blunder.」

These people died due to my misjudgement. That's why this matter is my responsibility. Though it was already too late, I shall exterminate that small fry with my everything, the same goes for the demon race who did everything as they pleased in the north from here, they shall be destroyed.

But―― I wish to perform a small experiment before that.

I took out the subjugation picture book. The registration object of the subjugation picture book has been expanded after I cleared that easy dungeon, now it could register someone whose strength is above a certain standard.

I've tried various experiments with subjugation picture book after that but I failed to register normal monsters or undead into subjugation picture book. The only successful cases so far were Ifrit, Titan, and Deimos. Even though they weren't normal members of the subjugation picture book, they're registered as GIrimekhala and co's kin.

Though I had no idea, the current me could vaguely guess the reason. The registration in the subjugation picture book means linking the capture to my soul. In short, they need a certain level of strength to be able to form a link with my soul.

The same goes for the human and monster's corpses before me. But, the current me wishes to register them.

「Since not that much time has elapsed since their death. Their souls should be still around. Please, register them.」

But, the picture book maintained its eerie silence no matter how much I wished for it.

「Impossible huh…」

I heaved a sigh. Yeah, life is filled with ups and downs. The result of my actions was an irredeemable mistake. Dead couldn't be resurrected. That was the providence of this world.

In the end, I was the same as those low lives who toyed around with unrelated lives.

I wouldn't try to varnish it with sweet words. No matter how selfish I am, I was originally a self-righteous person, a mistake was a mistake. That's why I would never try to hide this sin under beautiful words. Something akin to boiling rage to my own mistake slowly rose up from my heart.

「Girimekhala, Beelze, are you there?」

『Right by your side…』

『Yesh.』

Girimekhala and Beelze appeared, kneeling before me.

「We're going to suppress the activity of the demon race in the north after I take care of that small fry called Sugar.」

『There's an Evil Army backing up the demon race in the north. What are we going to do about them?』

Beelze's mouth moved restlessly, making a wisping sound the moment the words "Evil Army" escaped from Girimekhala's mouth. Lately, I understand that this was Beelze's gesture when he was excited. Maybe he was originally related to those trashes from Evil Army. And then, upon seeing Beelze's excitement, I had no doubt that they were quite powerful.

「Evil Army? What's that?」

『The group from which the three headed wicked dragon who got slaughtered by you a while ago―― Azi Dahaka, came from.』

「A~h, the one who keep yapping around about game huh.」

Honestly, it was a trivial matter for me. I mean, it's not like the group to which that weakass dragon could beat me.

「The trial has ended. I'll deal with the aftermath. Don't try to stop me, this is my duty as the one responsible for this mess. Your job is to clean up the mobs.」

『As you wish!』

『With pleasure.』

After they nodded, I unsheathed Murasame from its scabbard strapped to my waist.

「Well then, time for slaughter.」

I felt so refreshed. I shall make an offering for these people, the victim. Sugar, or the Evil-whatever-Army. I shall kill you in the most humiliating way. (ED: Yeah!)

I realized that the tips of my lips rose to the limit. I entrusted myself to the boiling rage in myself.

――A while after Kai Heineman left to commit slaughter.

The subjugation picture book normally vanished back into Kai Heineman's body as soon as it finished its job. And yet, for a mysterious reason, the book still floated in the air.

The pages in the subjugation picture book flipped rapidly, lines of letters appeared inside of it.

――Registration of Tama into subjugation picture book―― Failed! Theoritically impossible.

――Registration of Chato into subjugation picture book――Failed! Theoritically impossible.

――Registration of Gilbert Loto Amelia into subjugation picture book――Failed? Theoritically… Impossible?

――Registration of Gilbert Loto Amelia into subjugation picture book――Fai, led!

――Registration of Gilbert Loto Amelia into subjugation picture book――Fai....... Led!

――Registration of Gilbert Loto Amelia into subjugation picture book――Fai............. Led!

――Registration of Gilbert Loto Amelia into subjugation picture book――Fai..................….. Led!

――Registration of Gilbert Loto Amelia into subjugation picture book――F-F-F-F-F-F-F-F-Fai…･･Led!

――Registration of Gilbert Loto Amelia into subjugation picture book――F-F-F-F-F-F-F-F-Fai…L-L-L-L-L-L-L-L-L-Led!

The letters appeared again, and again.

After it continued for several pages――

――Registration of Gilbert Loto Amelia into subjugation picture book――――――――――Success!

――Gilbert Loto Amelia is the possessor of subjugation picture book, thereby becoming the rightful kin of Kai Heineman.

――Creating soul link with his master, Kai Heineman―――――― Success!

――Recreate the flesh from the soul of Gilbert Loto Amelia――――Failed!

――Recreate the flesh from the soul of Gilbert Loto Amelia――――Failed!

Recreating the flesh from the soul of Gilbert Loto Amelia judged as impossible. Due to the effect of picture book owned by Kai Heineman, an alteration to Gilbert Loto Amelia's gift――[Supreme Mage(Special Class)] was made――――――Success―― Got [Soul Travenger(Returnee Soul)] title. Power acquisition――[Transformation]

Activating the effect of the new title――[Soul Travenger(Returnee Soul)]―――― Success.

 The soul of Gilbert Loto Amelia would be sent back from the present to a random point in the past at a fixed interval.
