Chapter 337: World Assimilation

Chapter 337: World Assimilation

“And? Am I right in assuming your weapon is that carriage?” (Naofumi)
“Kue.” (Fitoria)

Fitoria firmly nods.

“Last we met, you were able to detach it, right?” (Naofumi)
“Kue, kue.” (Fitoria)
“If you use your weapon long enough, you’ll eventually be able to take it off temporarily, she says.” (Midori)

How envious.
I want to learn to do that too, but perhaps the Vassals and Heroes work on different systems…
The Shield did go into dormancy for a while, but it would be nice if I could do that consciously.

“Did you copy the Tank-type body Rat made? Is that also counted as a carriage?” (Naofumi)
“Kue.” (Fitoria)
“Yes. I got the feeling that could be copied, so I went and made use of it, apparently.” (Midori)
“I see.” (Naofumi)

I don’t know if there’s a gap in power output, but it’s amazing that she could copy Rat’s Tank-type monster.
With this, we may be able to advance Rat’s plans in weapon-shaped monster-making. Well, that doesn’t matter right now.
But… is a Tank really a carriage?
It’s more like a vehicle, or something like that.

“To summarize, originally, there were four weapons that could be called legendary. Each one was able to select two vassals, making for eight in total. All together, that means there are 12 holy weapons circulating in this world. Glass, how was it in your world?” (Naofumi)
“Let’s see. In our world, there also existed twelve weapons. From them, I was selected as the vassal of the 『Fan』.” (Glass)
“I see.” (Naofumi)
“This world… hasn’t experienced any particular damage. What happened to its guardian beasts?” (Glass)
“Guardian Beasts?” (Trash)

When the conversation had just gotten back on track, Trash posed a question to Glass.
I just learned about their duty from Gaelion a little while ago.
But perceptive people like Trash may have already picked up on it.

“In order to prevent the wave… the assimilation of worlds, there exist certain beasts. In order to protect the world, they collect the souls of its inhabitants. It may be a cruel method, but…” (Glass)
“So you mean the four spirits?” (Trash)
“That’s right. In this world, three have already been eliminated. It seems that the descriptions of their nature and other explanations passed down by the past heroes were all destroyed by someone’s hand.” (Naofumi)
“… My world’s have all been eliminated already. The only method left to me was to… kill all the heroes of this world.” (Glass)

Glass puts her hand on her chest with a relieved expression.
It’s not like she’s attacking because she wants to.
At least, that’s what I get by watching her.

It may seem selfish from our point of view, but the same can be said in reverse.
I mean, if we don’t use the power of the Four Beasts, we’ll have to eliminate Glass’s world.

“It may be just a little, but the worlds have assimilated in some parts. At the moment, my world’s inhabitants are now slightly closer to becoming yours, something like that.” (Glass)
“I guess that’s how it is. And what do your people wish for?” (Naofumi)
“To suppress the assimilation to as great an extent as possible. If possible, we also don’t wish for any more sacrifices from our side.” (Glass)

So Glass’s world isn’t completely gone, but the assimilation has taken most of it away.
Because of that, Glass came to seek aid from us.

“We hope that you will offer at least half of your lives to your guardian beasts.” (Glass)
“… Are you sane?” (Naofumi)

Since Glass is on the asking side, there’s no helping it, but asking us to sacrifice half our population…
She doesn’t seem happy about proposing it either.
It’s easy to imagine just how hard of a choice it is for her.

It’s that. In an old Sci-Fi novel, I’ve read something like this
The world became too polluted for human inhabitation, so a small fraction of the population set out for the stars to find a new place to call home. I think.
I do believe that it is strange that the current fantasy situation overlaps with Sci-Fi though.
But, Glass’s world seems to have been cornered quite far.

Of course, the situation is the same for us.
If we just stand back and watch, our world will definitely fall to ruin.
To save the many or the few. Such a choice has been imposed on us…
In that sense, those of Glass’s world, who’ve already reached their decision, have a better grasp of the situation than us.

“I know. It’s our final option. But since part of this world has already been eaten away, in order to ensure the survival of the races that live on your world, it isn’t the worst option. Of course, if you have a better one, then it’s a different story.” (Glass)

If we had something like that, we would already be working on it.
But those sacrifices aren’t just going to say, “Go ahead,” and let themselves be killed.

-but it may be something we have to do.

I can tell since I’ve survived up until now.
In this world, pretty words aren’t enough to bring an end to anything.
Whenever someone gains, someone loses.
Having all parties benefit rarely ever happens.

In order to ensure a third survives, we kill the other two thirds.
This truly is… a shitty world.

Even so, we have to make a choice.
Of course, that truly is a final option.

“… What about your world?” (Naofumi)

Glass averts her gaze.

“The vanguard of the enemy forces, one with memories of another world, left our world in chaos. Suspicion raged on about who the reincarnated one was, and when the world was in grave peril, my comrades began killing one another… you can laugh if you want.” (Glass)

It appears that a reincarnated like Tact caused the death of the Four Heroes and all but one of their vassals.
It’s scary that with one wrong step, the same could have happened to us.

“I do feel like bursting into laughter, but we’re on the same boat. How about you crack a smile?” (Naofumi)

The Seven Stars were assassinated.
Tact schemed.
Faubley went to war.

Really, he did a perfect job of making a mess of things.
An idiot like that thought he could save the world? That’s too much even for a joke.

“Now then, let’s leave that behind, and see what information we have left.” (Naofumi)

Info on the world we’re opposing.
Looking at Glass’s attitude, we aren’t much different.

“Our world was left with information on what the wave was, but everything else was lost over time… just how many times… did we fight with other worlds to save our own?” (Glass)
“I see… Glass, your world’s wave… what number is it?” (Naofumi)

This was the worst possibility I thought of.
Even if their world comes to a close, will their battle ever end?

If it was to be in a hundred years, it would be fine.
If it was in decades, we would still be prepared to make a bitter decision.
But what if it were in a few years, a few months, a few weeks?

Will we simply be fighting an endless battle?
No, if it will continue no matter what…

“We’ve fought a countless number of battles. At the start, we fought your world, but sometimes, a different world would appear in our sky. Perhaps it was because of the power of your world’s Guardian Beasts.” (Glass)
“Ah, I see… Our first meeting was… four months ago.” (Naofumi)
“At that time, the only thing I knew was the nature of the wave. There’s a world of difference between the me of back then and the me of now.” (Glass)

Yes the current us would easily be able to defeat Glass when she fought us back then.
And the same goes for Glass now.
In our joint battle, she displayed quite a bit of strength.

“Um, Naofumi-san, why is it that we cannot let the worlds to assimilate anymore?” (Itsuki)

Itsuki asks a question.
Ah, that’s right. I explained what the wave was, but never why it had to be stopped no matter the cost.

“To put it simply… think of the world as a soap bubble floating in the wind.” (Naofumi)
“I… see…” (Itsuki)
“This bubble floats, collides with, and gets stuck to four others of similar size. But it has its limit. The next bubble to hit it will cause it to burst. You get it?” (Naofumi)
“… Somewhat…” (Itsuki)
“I see… The wave is a phenomenon where worlds assimilate, and while the other Heroes were able to survive through it, they were unable to prevent the phenomenon itself. This fits with my wife’s notes.” (Trash)

Trash picks up what I really want to talk about.

“From the start, the world had one holy weapon and two vassals. Another world got stuck on, and it became two and four… and in the previous wave-” (Trash)
“Yeah, we now have four holy weapons and eight vassals.” (Itsuki)
“To summarize, the stories of the past where Demi-Humans don’t seem to exist are those that were passed down before the wave, and by the collision of worlds, we became bound to the Demi-Human world? Naofumi-dono and Kawasumi-dono’s Shield and bow are… those of the Demi-Human side. That’s why they’re looked down upon within my country.” (Trash)
“Me too? I didn’t feel that I got that bad of a reception compared to Naofumi-san.” (Itsuki)
“In our long history, perhaps the Bow performed some feat and got accepted by the church.  But the Shield…” (Trash)
“I’ll bet the original weapon of the Demi-Human world was the Shield. The weapon probably had close ties to their land, so he probably didn’t work near Melromark.” (Itsuki)

These people are sharp.
Even without me saying anything, they reached their own conclusion.
You’re incomparable to how you were at the beginning, Trash.

“The details are unclear, but in the waves before these ones, our world became tied to the Demi-human’s, and this time, we’ve established a link with Glass’s. Is that correct?” (Trash)
“Yes, your hypothesis isn’t wrong.” (Glass)
“But… why does the wave require so much time? Though my wife wrote not of it, I have my own theories.” (Trash)
“Speak.” (Naofumi)
“Fumu… First, it’s because of the one controlling the one with memories of a life past. The ringleader of this incident.” (Trash)

Trash crosses his arms and gets lost in thought.

“Another possibility is… the assimilation-prevention measures the four beasts perform happen every time the wave comes around, and as if waiting for a fruit to ripen, the ringleader waits for them to collect… but that would make this ringleader much too long lived.” (Trash)
“No, you may be onto something. Try expanding your thoughts.” (Naofumi)
“… Understood. The one behind this must reap some profit by sending the world into ruin. That’s why he causes waves to happen and worlds to go to war, eventually destroying them… Of course, the Four Spirits prevent such things, so they reincarnate someone to go dispose of them. But… this train of thought leaves too many things unclear.” (Trash)
“That’s right.” (Naofumi)

Why doesn’t this ringleader get involved himself?
It’s safe to consider that they have some reason not to.
Even if these deductions are correct, what they lead us to is…

“That ringleader cannot come to this world, or perhaps… it’s a magical or spiritual phenomenon. Like an automatic system to control the world’s population…” (Trash)
“Itsuki, do you have any ideas? You were able to tell Tact was a reincarnated, right?” (Naofumi)
“That’s right, but in my world, it would be explained as a power they were unable to awaken to in life, or something… I’ve got nothing.” (Itsuki)

In my world, the books I’ve read with this theme have been quite varied.
So my thoughts may be way off the mark.
But I’ve seen a situation similar to this.

“In the stories of my world, there’s a certain someone who mediates reincarnations like these.” (Naofumi)

    21.- Reincarnation and Summon?
    Remember, “reincarnation” is not iqual to “summon”:
    I think i need to explain this more easily…how about cards: You cast a power card (life), but someone countered that card (murderer), your card (life) needs now to go to the graveyard (you are going to die), but just before that you cast copy with another card (after that we need “paste” but that´s only for computers, matrix reference is usufull here too), so you put the card in the game (even if it´s not actually the card)…now is the turn of Witch and she use the card resurrection on your card (that was on the graveyard) now his card is her card…
    It´s simple, right?
    Summon is like “Copy” or “Avatar”, but part of this can have bugs…
    Ressurrection is like “Reborn” and you are the same but with other body.
    So basically we had two cards…the card who is there in the game (avatar) and the other card who was on the graveyard just a second ago (independently of the other one) and now is in the game too, but on the other side.
    Now is clear, right?


    • whome says:

      No , because summoning is forcefully bringing the actual entity to you, not creating a copy or avatar. That would be cloning, or creating a simulacrum or homunculus, or something along those lines. The 4 heroes were summoned, in that they were wholly brought from another world.


      • Mario says:

        …Well, if you are talking about the players i think that too,,, i mean bio-technology (i guess genius can do that) but that´s only for the part of science…magic of the spirits is important too…something like cacoons with the shape of people in the other world and in the VR world they send information later is received and that will function like a brain…like Mii-kun first and after that everything is possible (a new species for example)…But you are talking about that? i am not sure…well, it´s not like it´s important since all this is just a theory. Yes, summon or rencarnation can be like that too it is not like i am an authority in the matter and it seem plausible. Even so, both part of the same principle i explained before…one is the option “copy” and the other is “cut”.

    • Yoraikun says:

      Again, I simply hope that you don’t start to hate this series when it doesn’t turn out how you hoped. In the first place, you presented but a possibility. It’s Russel’s Teapot with each successive chapter being an increase in our space surveillance ability. There’s been nothing you’ve given to disprove that this is but a world in need of saving. That everyone’s but a person struggling to live within this godforsaken world. You have to equate it all to a simple game with variables and players. But this is reality. The entire story was about how the world was no game. How people had to accept to take responsibility for their own actions. In the end, I merely feel sorrow for you, and I hope you don’t become one who hates the ending merely because you deny it.

      Why is it that people cannot live and die as humans should? Why is it that people can’t just be evil and good? Why must everybody be the same, when there as many people in this world as there are stars in the sky? Why can noone have a past where its people actually do die?


      • Mario says:

        ….Yoraikun, we already talked about this…and apparently you did not read all the theories, of course it´s not a game, who say that? (all go wrong actually and they never knew it was a real world until their travel to that world (maybe that was bad of Naofumi)…after that they were scared), but i can´t put words that describe this so, how about magic or science (magic-game that it´s not a game?)….if it´s for my safety, thanks, i actually think you are a good pal.
        …if you understand, but you are not cool with this i can´t do a thing…maybe someone else can make a better theory…i can always change things thanks to new information, but i don´t expect to be a big change…


        • Mario says:

          The world was real, but the Avatars were Avatars, but thanks to the incident the Avatars in a real world became ral persons…they were scared…with a different language (not the language of the wave)…but a contry is somehow similar to japan/china…(maybe that´s for Genius Naofumi, but who knows)…at least you can understand my point.


        • Mario says:

          …Sigh…if only the author was here.


    • Darthfumi says:

      Mario just, just stop.


  4. ArcGeist says:

    The merging of world becoming worse, we all know what that means…


  5. Answer above says:

    The ringleader is Hitogami!


  6. moredrowsy says:

    Perhaps my memory is juggled, but what exactly is the wave? Are they the previous world’s inhabitants invading or are they monsters spawned anew out of nowhere?


    • whome says:

      The wave is basically one world pressing on another, creating a point where they intersect (the rift). The monsters are the other world’s creatures spilling through, though I’m not so sure why they’re coming through as a crowd.


  7. anon21 says:



  8. whome says:

    Thanks for the chapter!

    A lot of pieces have finally fallen into place!


  9. I just want to know something… what benefits is gaining this asshole god from drestroying his own worlds?… and what’s Naofumi? his whole existence is a mistery… from the beggining he had a guide for all the plot in the waves and a manual for a hero… his world is so damn suspicous..


    • Uhl says:

      What the god (or gods) responsible for this gain is still up in the air. As for Naofumi, he got jack squat. He had a book fall near him with only the briefest explanation on what the weapons are (everything else was blank) before he collapsed, fainted or died, not sure which, and he wound up in Melromark, where he was treated like shit by EVERYONE, until it became known that he’s actually the MOST heroic of the heroes in the series, and people started flocking to him with kindness instead of fire and pitchforks.


  10. teppy says:



  11. Mushoku Tensei? final boss is god?


  12. Martinik says:

    The magic truck driver who runs over people to reincarnate them?
