Ajuka things I don't remember

Thanks, I've already found them. Regarding Mitsuya, he only mentions two celestial bodies, not several, so I think this would only qualify as 4-C instead of 4-B. I say this mainly because the novel gives the number of created bodies.
And Ajuka's would also only qualify as 4-C (although in English it only mentions two celestial bodies at night, which, depending on the context, are moons with a sun, so... kind of weird).
Personally, I don't agree that when creating a terrain, they also create celestial bodies, mainly because they never imply that they're real, but rather simulations. But lowering them from 4-B to 4-C would be a good idea.

Although I wonder where exactly the Solar System value in Draig's profile comes from...

PS: Mitsuya's dimension is in volume 20, and Ajuka's is in volume 21.

 

[Tom4t0GG789]

Hey, I have a question about something that I don't know if it's a retcon or an inconsistency.

In Volume 5 Issei says that in the underworld there is no sun or moon originally, and that they created an artificial moon with the power of the current Maou

But in volume 0, a prequel to the original series, it says that before Sirzechs, Serafall, Ajuka and Falbium became the current Maou there was already a sun

“I received a letter from the Maou house. They said that, in the near future, successors could inherit the right to be called "Maous". And perhaps at the same time, they will again declare war between the three factions.” Venelana's expression darkened in response to these words. Zeoticus looked at the sky from the window. The only sun in the Underworld leapt into his eyes. "... The Underworld will soon fall into chaos" Said the head of the Gremory Family, fearing fate. The foreseeable danger being that the successors who inherited the name "Maou", there were many noble families in hiding, who were against this. (Vol.0)

Is this a mistake on Ishibumi's part or a retcon? Because looking at the mentions after volume 5, they don't mention anything about a sun in the underworld.

HIGH SCHOOL DXD COSMOLOGY DEBUNK (5-B WORLDS)

Before starting I want to clarify that I will only talk about the mentions of universal/infinite sizes in the light novel, based on the Japanese version This is the previously accepted cosmology blog https://vsbattles.fandom.com/wiki/High_School_DxD_Cosmology_Page Agree: Phoenks...

[Dragongod224]

It feels like the DxD descalers have shifted from disputing specific statements to outright denying the entire work, as if it doesn't exist. The staff seem to be agreeing with this approach, which is surprising. If scaling work is based solely on denial, then what's the basis for scaling in the first place? Since the approach seems to be based on denial rather than evaluating the source material or other relevant factors.

We gotta debunk this verse to Planet Level ASAP!!!

 

[Dragongod224]

Nah, below 11-C

 

[Thehunter077]

Man, you guys can't catch a break, got straight to the face(debunking to 5-B) and eat uppercut(debunk to 5-B but is accepted)

 

[Drite77]

Some questions about Issei, in his profile it says he can reduce someone's statistics until they are eliminated, how long does that take to happen? If someone is say, 3 times stronger, they would get AP stomped or would that be a fair fight? And if not, would using Volume 5 Issei be enough for that not to happen (Since the references mention that only happening in Volume 6)?

And for his Welsh Sonic Boost technique, is that a transformation or is that an attack he uses?

 

[Burning_Full_Fingers]

Since we are having revisions (again), I have to think about Issei’s feat of vaporizing the vast plateau, containing mountain ranges, forests and rivers, etc from north to south, which happened in DX 4. It’s also probably his best destruction feat with DxD G so far.

So I asked numerous AIs this question:

What is the average sized plateau in the world that has its own mountain ranges, forests and rivers

I received these answers:

Claude AI



For a plateau with its own mountain ranges, forests, and river systems, a reasonable average size would be roughly:

200,000 - 500,000 km²

This range allows enough space for:

• River systems to form and develop watersheds
• Mountain ranges to exist within or along borders
• Diverse ecosystems including forests

Smaller plateaus (under 100,000 km²) can still have rivers and forests, but are less likely to contain significant mountain ranges within them.

A good middle estimate would be around 300,000 km².

ChatGPT (free)

Plateaus that are big enough to contain mountain ranges, forests, and major rivers
These tend to be very large—usually:
100,000 km² to over 2,500,000 km²
(For comparison:
– 100,000 km² ≈ size of Iceland
– 1,000,000+ km² ≈ size of Egypt)
Why this range?
To have mountain ranges, internal river systems, and large forests, a plateau must be:

• High and broad enough to host its own climate zones
• Large enough for rivers to originate and flow long distances
• Geologically complex enough to include mountain ridges

Examples to give you an idea of typical size

Plateau	Size (km²)	Has its own mountains?	Forests?	Rivers?
Tibetan Plateau	~2.5 million km²	Yes (Himalayas on edges, internal ranges)	Yes	Sources of Yangtze, Yellow, Mekong
Ethiopian Highlands	~1.1 million km²	Yes	Yes	Blue Nile originates here
Deccan Plateau (India)	~1.9 million km²	Yes (Ghats, internal hills)	Yes	Godavari, Krishna, Kaveri
Altiplano (Bolivia/Peru)	~170,000 km²	Yes	Some	Internal drainage + rivers

So what is the “average”?
For a plateau that fits all your criteria, the realistic average is roughly:
500,000–1,000,000 km²
This is large enough to hold entire mountain systems, different biomes, and major rivers—but smaller than the extreme giant like Tibet.

ChatGPT (paid)

If I were mapping a fictional world or looking for a “reasonable plateau” to match your criteria (has its own mountains/ranges, forests or rivers), I’d plan for something like 100,000–300,000 km², maybe with elevation varying enough to allow rivers and mountains. That size mimics real-world plateaus like the Colorado Plateau or sections of the Deccan Plateau — enough scale for complexity, but not unmanageably huge.

Grok says the medium for vast plateaus that have mountain ranges with forest and river systems is at least about 500000km squared.

So, if you average only the well-known mid-sized plateaus that unmistakably have mountain borders/ranges, major river systems, and significant forest cover, the rough average falls in the 500,000 – 800,000 km² range

Then I guess BxB Issei will scale between 6-C to High 6-C for vaporizing the mountain:

AP Upgrade

We can start scaling up from there.

Yes, I believe we should use the "pulverization" value for the mountain's destruction in volume 5. I requested translations of the Japanese version some time ago, and they don't say "vaporization" but rather "pulverization."
(Except in volume 21, where it is implied.)

I also did a recent calculation and it came out high 6-B

Really, can I see that? I remember someone posting the Japanese version years ago but I don’t remember pulverization.

[Tom4t0GG789]

Really, can I see that? I remember someone posting the Japanese version years ago but I don’t remember pulverization.

My main argument for calling it pulverization (excluding its D×D form) is that when Issei launched an attack more powerful than the one that destroyed the mountain, it only created a crater without any further description.

I also consulted the translation of the mountain feat in Vol. 2. It said that, based on the context, it could mean fragmentation.

我没有看到纳秒的描述。在日语中，纳秒通常写成 ナノ秒 或 ナノメートル。 有人可以帮我翻译这段话吗？我想知道是否像英文版本一样提到了纳秒运动。

Under that translation, does it mean it destroyed the entire mountain or ripped off part of it? What's more, what's the destruction of the attack? Some translators tell me it blew up, so I assumed it fragmented. What do you think?

vsbattles.com

Some time later I asked him about the feats we used to support the vaporization level (Volume 9 and DX 4) and vaporization was not mentioned either.

Can someone help me translate this?

But where vaporization is shown, or at least implied, is when Vali destroys a set of mountains in his Diabolos Lucifer form
Here's the calculation I did if you want to see it.

This is from volume 2; he specifically held back the power because he didn’t want to replicate the mountain destruction.

But I need to hold back. The power that destroyed the mountain is bad. It may affect Buchou’s strategy if I destroy the school building. I shoot it while holding back—.

Some time later I asked him about the feats we used to support the vaporization level (Volume 9 and DX 4) and vaporization was not mentioned either.

For Volume 9, the anime supports vaporization elements as we visibly see some heat and some steam/vapor elements. If I’m remembering correctly.

As for DX 4, I don’t think you need a “vaporize” statement since river systems were destroyed and you can’t really “fragment” or “pulverize” bodies of water entirely.

Here's the calculation I did if you want to see it.

That’s good. Can we calc the one from DX 4 too?

 

[Tom4t0GG789]

This is from volume 2; he specifically held back the power because he didn’t want to replicate the mountain destruction.

What I meant is that in Volume 2 there’s no solid evidence of vaporization; even the anime implies pulverization, as seen with the destruction of the mountain and tennis court.

For Volume 9, the anime supports vaporization elements as we visibly see some heat and some steam/vapor elements. If I’m remembering correctly.

As for DX 4, I don’t think you need a “vaporize” statement since river systems were destroyed and you can’t really “fragment” or “pulverize” bodies of water entirely.

The term “vaporize” isn’t required, but evidence must support it; for example, my calculation showed Vali rendering land barren. With DX 4 and Vol 9 isn’t an issue since that feat occurs in Diabolos Dragon form and the stronger blast (Visually, the anime shows him electrically charged... New hax? )

That’s good. Can we calc the one from DX 4 too?

Yes, I feel the current calculation is incorrect and I'd like to recalculate it.

Yes, I'm waiting for that thread to be accepted so I can send the one with the verse scale. We already have some achievements.

 

[Burning_Full_Fingers]

Okay, yeah, I don’t mind that. I think we agreed on pulverization on that before.

The term “vaporize” isn’t required, but evidence must support it;

Well yes, and the anime supports that for volume 9. We can’t see the results in the novel of course, so I don’t see why the anime can’t be used since we are using it for Dragon Shot already.

for example, my calculation showed Vali rendering land barren. With DX 4 and Vol 9 isn’t an issue since that feat occurs in Diabolos Dragon form and the stronger blast

Yes, but Issei rendered the land barren as well. In both the ORC translation, he says “barren wasteland” with all the valleys, rivers, etc “completely disappearing” and the Seiji translation says “bare earth.” There’s not really much difference.

After using Infinity Blaster, the scene before my eyes had turned into a completely barren landscape! All of the forests, rivers and plains that had originally been in front of my muzzles had completely disappeared, leaving behind only a wasteland with no shelter.

Like I also said, it’s not possible to “pulverize” river systems so vaporization on a large scale had to have happened. Issei’s attacks are also not any less destructive than Vali’s anyway. So I think overall, vaporization is supported.

Yes, I feel the current calculation is incorrect and I'd like to recalculate it.

alright, but what’s up with it though?

So we agree on everything, great!

alright, but what’s up with it though?

Yes, I feel it's wrong because we're assuming it destroyed a small mountain range, but the location is based on an area with a plateau and two mountain ranges, so the most appropriate thing would be to find a place that fits that description and calculate the destruction of the mountain range.

Probably. I forgot to even add the plains in the field in the prompt I gave AI.

Using the description of mountain ranges, forests, rivers, and plains with this:

What is the average size of a vast plateau that has mountain ranges, rivers, forests and plains

it’s suggesting these averages:

AVERAGE SIZE RANGE​

For a plateau to be “vast” and structurally complex enough to include mountain ranges, forests, river systems, and plains, the typical size is:

​

This is the range where most large, multi-biome plateaus fall.

If we take the average of the real examples:

• (2,500,000 + 1,000,000 + 250,000 + 3,700,000 + 1,000,000) / 5
  ≈ 1,690,000 km²

So a good​

~1.7 million km²​

Estimated Average for Diverse Vast Plateaus


If we average the core areas of the most diverse “vast” examples (Tibetan, Deccan core, Colorado, plus similar like Ethiopian Highlands ~1M km² and Iranian ~3.7M but less forested): roughly 1–1.5 million km².


The Tibetan Plateau is the standout “vast” example with full diversity, so many sources highlight its ~2.5 million km² as representative of the largest/multifaceted type.

Maybe we can look for the closest equivalent to the figures.

If I ask for the closest real world equivalent, it keeps suggesting Tibetan Plateau as the closest but that’s like the biggest plateau ever lol.

I think using the average size ut gave would be fine, I guess.

I honestly have no problem using Tibet; in the end, Issei only destroyed the mountain ranges, rivers, and forests, and according to the text, the plateau remains intact.

I found two national parks that perfectly matched the field description in Volume 22 and used 75% of their destruction.

The other one I found was a plateau in Türkiye that matched.

Is there also any way to check these below, which are on a level that can “change the world map”

This one is for Trihexa’s nerfed/split body.

Volume 21, Life 2:

The Trihexa which appeared in Europe also blew away the mountains, lakes and forests with its breath of fire—. …It was mass destruction on a level which would change the world map.

This one is for Loki in chapter 5 of EX:

I can feel something completely insane since my body trembles violently after I take measure on that mass of aura. Once it is shot, this entire coastal area… no, the world map will be carved and repainted.

Then I don’t know if this one for Serafall from volume 15 also counts:

T-That’s certainly true…… If she tries, this person can destroy a whole island with a single shot of her demonic power! It would be a serious problem if the person who is in charge of diplomatic matters changes the map of the human world.

Maybe AI research can also help here.

It's too ambiguous to say it can be calculated. We could use Serafall's feat, but it's complicated.

 

[Burning_Full_Fingers]

I guess it might not be specific enough, though the Trihexa one is probably at least similar to what we have for DxD Issei in terms of scale. Maybe superior though, with the world map comparison.

I see, it’d have been nice if we could somehow get something from Serafall, since it’s useful for Maou scaling.

nice work, but eh, the first park with v22 seems comparatively small with what the other AIs suggested.

as for the first park, could there be another close alternative because it seems to have glaciers and ice fields from a quick search. there’s no indication of such landmarks in volume 22.

I’m not knowledgeable enough on calcs to contribute anything else.

Also the Boost thread should probably be bumped.

Not much hints about whether Shin DxD will released this year, going by the authors’ tweets.

It seems more likely for Junior and Slash Dog; although honestly, I don’t think many people care for Slash Dog at this point. Ishibumi has basically killed the hype with such a long time off.
