Kazemaru's Exploding Shuriken

The Feat

We're really scraping the bottom of the barrel when an exploding fucking tree is up to be measured


Yusuke = 260 pixels
Tree Diameter = 37 pixels
Explosion Diameter = 504 pixels

Tree Diameter/Yusuke = 0.142

Explosion Diameter/Yusuke = 1.938

Yusuke = 1.7 meters
Tree Diameter = 0.241 meters
Explosion Diameter = 3.295 meters

Cylinder Volume = PIr^2*H

r = Tree Diameter/2
H = Explosion Diameter = Length of Tree Destroyed

Tree Destruction Volume = 0.15 m^3

8.34 j/cc

Single Exploding Shuriken Yield = 1,251,000 joules or 298.996 grams

Suppose its worth noting he does eat like 3 of these and only gets KOed

And it was only 1 causing the tree's destruction as Kazemaru only threw 4 and only 3 were chasing him after detonation

So

Kazemaru's Durability (3 Shuriken) = 3,753,000 joules or 896.989 grams
Kazemaru's 4 Exploding Shuriken Yield = 5,004,000 joules or 1.196 kilograms

Yusuke's Exhausted Reiki Rage Explosion

So here's the Feat

Kuwabara pisses off a Yusuke resigned to and regretting he's going to die to a bunch of fucking fish

He promptly tells him off by exploding both literally and figuratively with anger

All bearing in mind that he no longer has the Reiki to use his Reigan or do much more than throw one more punch at Rando

He briefly got a second wind due to rage at Shaolin/Shorin (Rando's weaker human self) fucking up Kuwabara, but he's ultimately spent by the time he's up against Rando transformed

What I mean to say is, Yusuke's spent and what he can accomplish fresh would be much more impressive.

All the same, here's the calc


First Image, Middle Right Panel

Yusuke = 329 pixel
Fish = 101 pixels

Fish/Yusuke = 0.307

Yusuke = 1.7 meters
Fish = 0.522 meters

Second Image

Fish = 28 pixels
Water Diameter = 275 pixels
Water Height = 385 pixels

Water Diameter/Fish = 9.821

Water Height/Fish = 13.75

Water Diameter = 5.127 meters
Water Height = 7.178 meters

Center of Mass (Cone) = Water Height/4 = 1.795 meters

Cone Volume = (PIr^2*H)/3

r = Water Diameter/2
H = Water Height

Water Volume = 49.372 m^3

Water Density = 1,000 kg/m^3

Water Mass = 49,372 kilograms

First Image, Bottom Panel

First, the fish compared to the height in the background

Fish = 107 pixels
Pond Depth = 1637 pixels

Pond Depth/Fish = 15.299

Pond Depth = 7.986 meters

Now how far above the bottom Yusuke is

Yusuke = 1047 pixels
Height Above Bottom = 262 pixels

Height Above Bottom/Yusuke = 0.25

Height Above Bottom = 0.425 meters

Thus

Water Travel to Surface = Pond Depth - Height Above Bottom

Water Travel to Surface = 7.561 meters

Total Center of Mass Height Change = Water Travel to Surface + Center of Mass

Total Center of Mass Height Change = 9.356 meters

PE = MGH

M = Mass of Water
G = 9.8 m/s^2

H = Total Center of Mass Height Change

Half Reiki Explosion Yield = 4,526,859 joules

I say half because obviously we're only able to use the visual to derive the power of the top half of the explosion (remember, omnidirectional, and made easy because the detonation occurs in the water), thus to get the full energy you multiply this result by 2.

Yusuke's Reiki Explosion Yield = 9,053,718 joules or 2.164 kilograms

Cool

Kazemaru's Reiki blast is also compared to a Howitzer by Botan in Viz (somewhat hyperbolically, but in a downward direction as Yusuke's own attack was reduced to being a water pistol [despite being beyond shit that can wreck trees] for sake of discussing disparity), but without checking the raw I'm not doing shit with that

And something about supersonic wind vortices by Shaolin/Shorin in Viz, but again, raw needs a look
