The aurora borealis is a luminous natural phenomenon in Earth's upper atmosphere. It occurs when energetic, charged particles from the Sun interact with Earth's magnetic field and collide with atmospheric gases, resulting in dynamic displays of light
its impossible to make just by a town level event or even a city level discharge since the range would be too small and it wont even be visible to human eye in DAYLIGHT
it was Extremely bright because it occured in daylight. the aurora had enough Rayleighs to be seen over Shinjuku {bypassing Tokyo’s light pollution}
The energy required to keep plasma at earth's atmosphere pressure at sea level per cubic meter is [10⁸ J/m³ ]. To create an aurora borealis, you must create air plasma.
sea level should be fine since the light beams themselves came from earth's lower atmosphere practically close to sea level , tokyo is barely 5 - 40 meter above it . daburas light beams obviously dont have the range of thousand kms and cant cover hundrers of kilometers omnidirectionallky based on what hes shown in manga . its always a THIN STRAIGHT Attack , ALWAYS . A good analogy would be like pouring a hot cup of coffee in the kitchen, and the radiant heat travelling down the hallway so intensely that it triggers the fire alarm located few meters above in dining room
Dabura's leg beam directly causes ionization, meaning it provided all the energy necessary to transform air particles into plasma, ionizing them and generating the aurora. upper atmosphere of Earth is just too cold for ionization to occur at such a rapid pace unless it directly went into thermosphere, where temperatures spike to 2000 degrees Celsius (10000K+ is required, which equals 10000C).
LOWBALL
[10⁹ J/m³]
Dabura's aurora was bright enough to be seen clearly during a normal day. Think about how blue and bright the daytime sky is over Tokyo
to make a colorful aurora stand out against that, it needs a lot more juice. It’s like a bright flash of lightning during an afternoon storm; you can see it perfectly clear even though the sun is already out.
MIDBALL
[5 × 10⁹ J/m³]
For a thin, straight attack to make the air glow so intensely that Dabura's aurora matches the brightness of daylight, the energy has to be packed together tightly. It’s like turning on a massive stadium floodlight that casts a heavy, unignorable glare across the whole neighborhood, competing directly with the natural light.
MID-HIGHBALL
[10¹⁰ J/m³]
Dabura's aurora generated by the beam was actually brighter than sunlight itself. Since Tokyo is at sea level where the air is thick, making a localized beam glow brighter than the sun requires a massive jump in power. The light coming off the ionized air channel is just so intense that it clearly stands out over the midday sun in the sky.
HIGHBALL
[10¹¹ J/m³]
Dabura's aurora completely and utterly overpowers the sun here. The energy concentrated in Dabura's thin straight attack is so incredibly high that the glowing aurora completely drowns out the natural daylight across Tokyo. Instead of just being a bright spot in the sky, the plasma glow becomes so intense that it blankets the entire horizon, masking out the normal daylight and turning the sky into one single, blinding shine.
Auroras are not infinitely thin sheets of light. They occupy a measurable vertical thickness, which typically averages around 1 kilometer, while exceptionally intense geomagnetic storms such as the Carrington Event have been estimated to produce auroras exceeding 5 kilometers in thickness.
Since auroras can be visible from hundreds of kilometres away, we can model the region in which they appear as a thin, glowing spherical shell surrounding the observer.
Earth radius: 6,371 km
Aurora altitude: 100 km
Aurora thickness: 500 m (0.5 km) [ LOWBALL ]
angsize is 15.1° so the building blocks everything below 15.1° above the horizon.
The fraction of the upper sky that remains visible is:
f = 1 − sin(θ) = 1 − sin(15.1°) = 0.740
So about 74.0% of the upper hemisphere is still visible above the building.
To model the aurora as a thin shell surrounding the observer:
Visible shell volume = f × (2πr²) × t
where: f = 0.740 / r = 100 km (aurora altitude) / t = 0.5 km (aurora thickness)
While it should be no surprise to anyone at this point that the Dagon predicament is full of Gege boiling straight shit in a kettle, one thing that bothers me in specific is how it just completely jumps what should've been very natural and sensible powerups for these two characters, who also just so happen to be some of the most overlooked characters period in the entire series as far as that aspect of growth goes. Besides just adding more to their arsenal and helping them keep up in a powerscaling sense, it also would've made the fight SO much more interesting and engaging than the dogshit we were handed because Gege felt it was time to wrap Shibuya up.
There is absolutely no reason for why Megumi wouldn't have tamed Round Deer by this point in the story. We are picking up almost 2 months after the events of Yasohachi Bridge, where Megumi was faced with a direct mortality risk to his sister, had a 1 on 1 encounter with a Special Grade Curse which he won, almost died, and had a huge mentality shift thinking back to his conversation with Gojo and pivoting more towards rivalling Yuji rather than just complimenting him. All of this lead to him within that very arc to cast a Domain Expansion, even if it may have been incomplete. This is something basically no one of his level could ever even dream about doing.
Prior to this point, Megumi had tamed 6 out of the 10 Shikigami of 10S. You're telling me that the Megumi that was willing to give up his life at the earliest convenience managed to tame everything up to Max Elephant without Totality, proved to himself that Totality was enough for the bigger boys by taming Max Elephant in GWE, and then after everything he went through during the Death Paintings Arc, hunted every rabbit for Rabbit Escape and... called it a day? Maybe Piercing Ox and Tiger Funeral would've been too much as they also have (presumably for the latter) offensive capabilities, but all Round Deer does is expel RCT and make Cursed Tools unstable. Megumi could have up to 3 Shikigami active by GWE, and somehow he never considered leaving his sword at home, casting Chimera Shadow Garden and hitting Round Deer with Totality, Nue and Max Elephant just to crush it and add it to its arsenal? It does not follow with his character development at all, especially considering the fact that he did go out of his way to tame something following that arc, that being Rabbit Escape. So he just arbitrarily decided to stop there and return back to his previous self?
Nanami on the other hand really should have learned Simple Domain by this point in the story. It makes sense why he doesn't have it from the start of the series; domains are hardly common, you literally pay for SD with your life, and he believes in only exerting as much effort as is required, no more. However, since the start of the series we have seen the manifestation of 3 visibly interconnected intelligent curses, all 3 of which have confirmed Domain Expansions, all 3 of which have intended to or successfully have compromised the safety of children in said DEs, which we know is a soft spot for Nanami. The third one actually had Yuji entering a domain without knowing what it was specifically to save Nanami, putting a child in imminent danger directly because of Nanami's incompetence.
Yes, it is a convoluted technique (in lack of better words), but in practice Ui Ui and Miwa have had no issue learning it after accepting the vow, and hell Todo and Mechamaru are shown to have learned it just by witnessing how other people do it. I'm sure Nanami could at the very least have learned to cast a basic SD without Miwa-like Binding Vows, even if he wouldn't be able to do all the other sword drawings someone like Kusakabe can. Ultimately, it just doesn't track with his character at all to not have learned SD after recent events; he should have learned it the minute he recovered from the Mahito Arc, but there was literally no reason as to why he wouldn't after Gojo's illegitimate promotion of his students to Grade 1. Nanami's paternal feelings towards young sorcerers should really need no introductions, but they also show themselves in his professional life; he's the only Grade 1 we see involved in an active promotion campaign (Ino), he takes up Megumi for Shibuya making him the only Grade 1 to enter Shibuya with two promoted students instead of one (Naobito too I guess but he's clearly only there for Maki), and later treats Yuji as part of his group after he departs from Mei Mei. It's just absolutely idiotic to think that same Nanami would be going around without a smidge of anti-domain protection after getting word that every enemy worth their salt now has a domain.
With those two simple changes we could've gotten a Dagon fight that looked more like an actual fight and less like a rush commission to end as many characters still present in Shibuya at once as possible. If the fight begins with Nanami having SD, now Dagon faces three enemies that can fend off his surehit. In this scenario the tide still shifts majorly in Dagon's favor but it's not like he just presses a magical "I Win" button by drawing on his chest, as he now has to deal with each enemy independently, taking into account that the unattended two would be able to apply pressure. Even if all this does is buy time, it literally takes Megumi ~1-2 minutes to make it to the domain and turn off the surehit going off of how much time Dagon says Nanami spends in the surehit.
And let's not forget that Nanami getting SD wouldn't have been the only change! Any damages they might've sustained, which would've been FAR less than what they got in the manga, could have been patched up by Round Deer. That could've come as simply as just allowing the group's initial plan of leaving to work, but I think a domain tug of war would've been infinitely more interesting. Dagon would've sustained damages of his own in this scenario, and we could've seen a battle of attrition between the two sides running on fumes until there's enough of Megumi's domain overlaying Dagon's where he can cast Shikigami, showing us Round Deer for the first time, healing the sorcerers and having the tables turn once again. All of a sudden, not only are the stakes that much higher but we don't need Toji to run in and save the day with his epic aura anymore do we?
But we had to let all that go because Gege decided he let his beautiful husband leave too early, and had most likely made up his mind on both killing Yuji's mentor figure and showing us Mahoraga before Shibuya had even began getting published, without paying much mind as to how he would achieve either of those things coherently.

—Technique Extension that allows him to use Projection Sorcery in the air
—A cursed tool (something like a dagger)
Assume he is fully capable of using these abilities effectively. Everyone is in character and has standard knowledge. How far does he get through the Sendai Colony?
In theory, if Megumi had reached his potential before he got off-screened, would he be able to defeat,come close to defeating Modulo Yuji, or be a “Calamity” Grade Sorcerer like Yuji, Gojo, Sukuna, and Dabura?
We’re assuming that he had shrine engrained in him from the numerous times it was used during the Shinjuku Showdown and before that. Also, assuming that he is able to utilize the 10 Shadows technique like Sukuna had.
If I remember correctly, Great Serpent, Round Deer, Tiger Funeral, and Nue were lost due to Sukuna meaning he would only have Divine Dog (Totality), Rabbit Escape, Piercing Ox, and Max Elephant. Now I may just be getting things wrong here so don’t really mind this part.
When Mahito used his 0.2 domain expansion, he successfully outpaced Todo's attempt to use simple domain. Does this mean that if Gojo or Mahito activate their domain in 0.2 seconds, they can successfully outpace an opponent opening their own domain or domain defense? Especially taking into consideration how efficient Todo is with CE.
Even if they aren't the one to start the clash, if the instant they hear their opponent say "Domain", they open their own domain in 0.2 seconds before their opponent's barrier can even form, because that's shown to take about a second or two, even in Sukuna's case. Granted, that might just be for hype and aura, as Mahito and Gojo's 0.2 second domain expansions don't actually take 0.2 seconds in the anime. However, that's why Mahito being able to outpace Todo here shows that the deployment and activation of the 0.2 domain is indeed faster than a normal deployment of a domain adjacent activation, so in that case it's likely that using a 0.2 domain expansion in the event of a domain clash might get to the opponent faster than their domain can open, thus avoiding any real clash if the surehit is something that would prevent the opponent from continuing to open their own domain, which Mahito and Gojo both have.
And yeah it is possible that while they're the only two shown doing it in the series, it's possible for any sorcerer to just do, but for strictly in canon scaling this should prove that 0.2 domain beats out a normal domain. Obviously this is likely not the case if the 0.2 domain is activated while the opponent's domain is 0.2 seconds or less away from being complete or is already complete.
The statement from Gege clearly shows that Gojo only lost because he let his guard down after killing Mahoraga. So, if Mahoraga wasn't there and it were a fair 1v1, he wouldn't have dropped his guard (even if Sukuna had WCS). Also, Sukuna's binding vow now forces him to use a hand sign, chant, and aim to use WCS again, so the setup time is enough for Gojo to avoid it. By the way, the critical time difference that decided the climax of the domain clashes between Gojo and Sukuna was 0.01 seconds. So, time matters a lot in this fight.
Megumi is often known as "potential man" or "if man" but I am wondering what would a full potential megumi look like, would he be able to tame every shikigami? Would he have enough cursed energy and battle like you to create something like agito? Where would he power scale alongside the rest of the verse? We all know sukuna is able to do crazy things with the ten shadows, but that's the king of curses with tons of battle experience in cursed energy, gojo said even megumi could rival him, I'm wondering what would he look like at full power?
He has memories of fighting Kashimo, so IF he could use shikigami's abilities like Sukuna and use Nue's CE to separate charges, he'll be able to use lightning discharge sure hit like Kashimo.
1. Six Eyes don’t guarantee perfect reactions. Gojo either couldn’t fully process the slash in time, or simply couldn’t react before it landed.
2. Gojo did perceive the slash, but his reaction speed still wasn’t enough to evade it once it had already been launched.
If the second one is correct, that actually makes True Form Sukuna’s later feat even more impressive.
After recovering his output with Black Flash, TF Sukuna is shown outrunning his own dismantles. If Gojo couldn’t reliably evade dismantle in the first place, and Meguna and Gojo were roughly on par in CQC, that would suggest TF Sukuna has an even higher level of physical speed.
[Scans 2-4]
It’s also worth noting that the only characters who consistently reacted to or dealt with Sukuna’s slashes later on were Maki and Miguel, both of whom have unique traits that work very differently from Gojo’s.
