Genbu's Physical Might

The Feat


Genbu = 1683 pixels
Genbu Head = 735 pixels

Genbu Head/Genbu = 0.437

Given Kuwabara comments on how large Genbu is?

Figure 2 meters tall is a fair estimate on his hunched over height.

Genbu = 2 meters
Genbu Head = 0.874 meters


Genbu Head = 196 pixels
Crater Radius = 361 pixels

Crater Radius/Genbu Head = 1.842

Crater Radius = 1.61 meters

Volume = (2/3)PIr1^2r2

r1 = Crater Radius
r2 = Crater Radius/2

Crater Volume = 4.368 m^3

200 j/cc

Genbu's Physical Might = 873,600,000 joules or 0.209 tons

Yusuke's First Reigan and His Final Clash with Suzaku

The First Feat and the Second Feat


Person = 30 pixels
Tower Diameter = 365 pixels

Tower Diameter/Person = 12.167

Person = 1.7 meters
Tower Diameter = 20.684 meters


Tower Diameter = 31 pixels
Dome Height = 31 pixels
Dome Diameter = 70 pixels

Dome Height/Tower Diameter = 1
Dome Diameter/Tower Diameter = 2.295

Dome Height = 20.684 meters
Dome Diameter = 47.47 meters

Now to find the hole thickness. Scan quality has improved enough to let me with this here.


Dome Diameter = 341 pixels
Hole Diameter = 125 pixels
Dome Thickness = 8 pixels

Hole Diameter/Dome Diameter = 0.367
Dome Thickness/Dome Diameter = 0.0235

Hole Diameter = 17.421 meters
Dome Thickness = 1.116 meters

Cylinder Volume = PIr^2*H

r = Hole Diameter/2
H = Dome Thickness

Hole Volume = 265.876 m^3

8 j/cc

Beginning of Saint Beast Arc Yusuke's Reigan Yield = 2,127,008,000 joules or 0.508 tons

A casual Reigan (without being fueled by life energy or Yusuke's more powerful emotions) with the destructive power comparable to a tomahawk cruise missile (a solid building level piece of real world military hardware). Not bad.

Now the dome feat

Hemisphere Volume = (2/3)PIr1^2r2

r1 = Dome Diameter/2
r2 = Dome Height

Dome Volume (Material + Empty Space) = 24,392.223 m^3

Next empty space

r1 = (Dome Diameter/2) - Dome Thickness
r2 = Dome Height - Dome Thickness

Empty Space Volume = 20,957.121 m^3

Total Dome Volume = Dome Volume (Material + Empty Space) - Empty Space Volume - Hole Volume

Total Dome Volume = 24,392.223 - 20,957.121 - 265.876 = 3,169.226 m^3

8 j/cc

Spirit Shotgun vs Shitigoku Ankoku Raikouhou Yield (Low End) = 25,353,808,000 joules or 6.06 tons

Both Suzaku and Yusuke contributed half that energy, so just divide the end results by 2 for their respective power.

What do I mean by low end though?

If you'll note here?

The entire final sequence of events?

It has to occur in less time than it takes the possessed human asshole teacher to swing and stab Keiko from arm's length away.

After all, the Whistle that controls the mind fuck worms is only demonstrated to be destroyed after the explosion of the Dome occurs (after all, we only see it and "hear" it crack and break after the explosion in ensuing panels after the explosion)

Ergo, the bulk of the mass is moving as fast as the explosion and I can figure out how fast from a range of reasonable human level speeds for an arm swing (though I'd be happy if someone could provide a concrete source on arm swing speed as opposed to rough approximates)

So, dome mass?

Rock Density = 2,700 kg/m^3

Dome Mass = 8,556,910.2 kilograms

Now the speed of the explosion/debris


Dome Radius = 171 pixels
Explosion Radius = 400 pixels

Explosion/Dome = 2.339

Explosion Radius = 55.516 meters


Average Human Arm = 0.8 meters

His arm looks like it'd need to move about 1/4th a circumference to hit a kneeling Keiko/Botan based on the position of his bicep related to his shoulder.

1/4th Circumference = (2PIr)/4

Stabbing Movement = 1.256 meters

Speed of Stab (low end) = 10 m/s
Speed of Stab (middle end) = 15 m/s
Speed of Stab (high end) = 20 m/s

Time Frame (low end) = 0.126 seconds
Time Frame (middle end) = 0.0837 seconds
Time Frame (high end) = 0.0628 seconds

Debris/Explosion Speed (low end) = 440.603 m/s
Debris/Explosion Speed (middle end) = 663.274 m/s
Debris/Explosion Speed (high end) = 884.013 m/s

KE = 0.5mv^2

m = Dome Mass
v = Debris/Explosion Speed

Spirit Shotgun vs Shitigoku Ankoku Raikouhou Yield ("low" end) = 830,580,782,459 joules or 198.514 tons
Spirit Shotgun vs Shitigoku Ankoku Raikouhou Yield (middle end) = 1,882,231,016,482 joules or 449.864 tons
Spirit Shotgun vs Shitigoku Ankoku Raikouhou Yield (high end) = 3,343,522,745,360 joules or 799.121 tons

And just divide each in half to figure out how powerful each Yusuke and Suzaku are individually

From what I vaguely know about human motor speed, the middle end probably fits the bill for a swinging limb of an average fucker.

Next up?

Byakko's Mei Kō Shō Kai Ha

The various feats from the fight

We know it at least reduces shit it hits to dust (both the scanlation and Viz), with an upper bound of being so energetic it destroys molecular bonds (only Viz bothered to mention).

Doesn't hurt its case that the SFX of "sizzle", like "hiss", is typically used for vaporization

Here's the raw at any rate


Byakko = 319 pixels
Byakko Head = 86 pixels
Platform Diameter = 372 pixels

Byakko Head/Byakko = 0.27
Platform Diameter/Byakko = 1.166

Byakko = 3 meters (apparently his approximate height)
Byakko Head = 0.81 meters
Platform Diameter = 3.498 meters


Platform Diameter = 329 pixels
Platform Height = 141 pixels
Pillar Top Diameter = 134 pixels
Pillar Bottom Diameter = 205 pixels
Pillar Height = 370 pixels

Platform Height/Platform Diameter = 0.429
Pillar Top Diameter/Platform Diameter = 0.407
Pillar Bottom Diameter/Platform Diameter = 0.623

Pillar Height/Platform Diameter = 1.125

Platform Height = 1.5 meters

Cylinder Volume = PIr^2*H

r = Platform Diameter/2
H = Platform Height

Platform Volume = 14.408 m^3

Pillar Top Diameter = 1.424 meters
Pillar Bottom Diameter = 2.179 meters
Pillar Height = 3.935 meters

Calculator

Pillar Volume = 10.177 m^3
Total Structure Volume = 24.585 m^3

200 j/cc (low end, pulverzation per dust)
30,852 j/cc (high end, molecular bond deconstruction)

Byakko's Mei Kō Shō Kai Ha Yield (Low End) = 4,917,000,000 joules or 1.175 tons
Byakko's Mei Kō Shō Kai Ha Yield (High End) = 758,496,420,000 joules or 181.285 tons

Next?

Kuwabara's Reiken Extension Speed

The Feat


Kuwabara = 1227 pixels
Reiki Sword = 564 pixels

Reiki Sword/Kuwabara = 0.46

Kuwabara = 1.8 meters
Reiki Sword = 0.828 meters


Kuwabara = 391 pixels
Extended Distance = 1291 pixels

Total Distance/Kuwabara = 3.302

Kuwabara = 1.8 meters
Total Distance = 5.944 meters
Length of Sword = 0.828 meters
Extended Distance = 5.116 meters (take the total distance and subtract the sword length)

Now between here and here? Looks like the beasts leaping after Kuwabara traveled about 0.1 meters at most (not really something I can measure, but from a rough eyeball, it seems about right)

Now, a bit of an assumption, but given they're clearly sprinting and formed from the hair of a Tiger? I figure the speed of a Tiger sprinting would be suitable for those pursuing Kuwabara.

So?

Hair Beast Speed (Low End) = 15.646 m/s
Hair Beast Speed (High End) = 17.882 m/s

Thus?

Time Frame (Low End) = 0.00639 seconds
Time Frame (High End) = 0.00559 seconds

Saint Beast Arc Kuwabara's Reiken Extension Speed (Low End) = 800.626 m/s or mach 2.353
Saint Beast Arc Kuwabara's Reiken Extension Speed (High End) = 915.206 m/s or mach 2.689

Was kind of rough, but I wasn't in the mood for being super exact I guess. Either way you slice it though? The feat ends up somewhere around transonic at a minimum, supersonic+ at a maximum. Kuwabara has 2 supersonic feats in this arc (the spirit detective arc, which encompasses a bunch of mini arcs like this one) to his name more or less.

Now a new one

Seiryu and Hiei's Speed

Scanlation of Seiryu's Feat

Viz's Translation of Seiryu's Feat

The Raw of Seiryu's Feat

Interesting to note being both Viz and the Scanlation fucked up

What Seiryu is saying in the Raw said:

絶対零度に近い凍気の拳を秒間百発たたきこんだ

Click to expand...

This?

Is talking about the time frame being 1 second as denoted by 秒間 the number of punches is 100 as demonstrated by 百 and Absolute Zero is covered by 絶対零度

I know fuck all Japanese, but I can at least feed results through a translator.

IIRC Cableguy15 (hope you're doing better shit nowadays dude where ever the fuck you are) commissioned this translated to similar result, but that's buried under 7 years of trashed threads no doubt...

That said, if anyone better can bother to do it, that'd be cool


And here you were probably wondering why I scaled Byakko's head

Now you know

Anyway, unlike vs Hiei, Seiryu doesn't bother to close the gap, so the projectile like air coming off his fists as he throws 100 punches has to cover the distance for him instead.

Byakko Head = 134 pixels
Seiryu Attack Travel = 771 pixels

Seiryu Attack Travel/Byakko Head = 5.754

Seiryu Attack Travel = 4.66 meters

Number of Attacks = 100

Total Attack Travel = 466 meters

Time Frame = 1 second

Seiryu's Speed = 466 m/s or mach 1.369

Cool

What about Hiei's?

His Feat Anyway

Well, per being the same scene, in the same chapter, derived from a value we didn't really have to measure? It's not calc stacking to note Hiei is able to swing his sword 16 times before Seiryu does little more than raise his right arm from down at his hip to parallel to his Shoulders.

Or, you know, about 1/4th the circumference of a circular motion.

Arm Length = 0.8 meters (the arm is bent, but I'll be treating the fastest part of the motion as towards the tip of his arm to keep shit with as few assumptions as possible)

1/4th Circumference = (2PIr)/4

r = Arm Length

Arm Movement = 1.256 meters

Now, Hiei?

Hiei Arm = 0.65 meters

Figure that for an arm length is suitably conservative given his height.

Per swing, I imagine a typical 1/3rd of a circumference for a circular motion fits the bill.

1/3rd Circumference = (2/PIr)

r = Hiei Arm

Hiei Slash = 1.361 meters

Number of Slashes = 16

Total Slash Distance = 21.776 meters

Hiei Total Slash Distance/Seiryu Arm Movement = 17.338

Saint Beast Hiei's Speed = 8,079 m/s or mach 23.742

Bearing in mind? Kuwabara could see jack shit (not that this matters too much given his own feats this arc), Kurama could only follow the first slash before (suggesting he's about 1/16th as fast as Hiei at the moment) and Yusuke could follow about half the strikes Hiei made (so, Yusuke, even prior to powering up over the course of his fight with Suzaku is about half as fast as Hiei).
