[Fancalc Alert] Toneri's moon slice speed

[u/waitletmepoopfirst]

After it was brought up recently I went back and took a look at the feat to get a clearer picture.

Toneri's sword starts expanding right after this point, at 5:14. We have no idea how to calculate how much it initially expands in the first large frame because we don't get a full image of it, but we do hear the same sound effect used for the expansion continue in the background until Toneri begins swinging his arm down at 5:21, when it changes to a different sound effect to describe the slash.

First of all, even trying to calc the extension time frame in this manner is extremely iffy because we have no idea if the blade was actually done expanding to its full length during any point in that window, or if it continued expanding while he started cutting.

That gave us a 7 second time frame btw.

Another method we could use is Toneri actually cutting the moon, which begins at 5:26 and ends at 5:33.

This is also a 7 second time frame.

The diameter of the moon is 3474 km = 3474000 m. But as seen in KerdicZ's comment the blade was actually probably about a fifth longer than the moon, or 4168800 m.

3474000/7=496286 m/s

496286/340 (the speed of sound in air) = Mach 1460, for the second method of the blade slashing the moon.

Using the first method (blade's expansion) gives us:

4168800/7 = 595543 m/s

595543/340 = Mach 1752

It's important to note that Toneri's arm speed should actually be below that because his arm just acted as a fulcrum for the blade, but that's even more unquantifiable so we'll just go with Mach 1460. At the very least, Naruto would have been reacting and running toward the blade that had Mach 1460-Mach 1752 speed.

Now it's even more important to note that the speed in the movie, which is the closest we can get to a legitimate time frame, may not even be accurate because this is anime and time in film in general is not always 1:1. But with what we can for sure determine, I don't see any problems with this.

You mean the one with an obvious wind up that Naruto had time to see coming before the actual attack was launched?

I actually don't think the attack hit Naruto on the initial expansion anyways. As the beam can be seen up fired up into the air, then a few moments later Naruto's hand makes contact, causing this.

...

So what was this?

The attack was fired, Naruto was running and met it halfway and that was it.

You can't tell the angle of the attack from that image. There's no way to know if it would meet him halfway or go above him.

[u/PotatoGod12 → u/[deleted]]

Point is, Naruto still, at the very least reacted to it and blocked it.

[u/[deleted] → u/PotatoGod12]

There's no proof he was able to react to it when there was an obvious wind up and the mach 1400-1700 attack didn't hit him on the initial expansion. It flew above his head which he then ran to and met.

...

Oh yeah, the wind up. When we fucking see in the scan provided by /u/kerdicz that Naruto was running towards the fucking attack with his cloak on. And it did hit him. Kinda like the first time, it didn't stop and shit, right? That was because he still hadn't hit it with his chakra covered arm. There was nothing to stop the beam from expanding until he put his arm infront of himself. Like, think of Goku vs Supes #2 from Deathbattle, though with alot more struggle and the attack actually having an effect.

Except Naruto decloaked himself and put his chakra into his arm before he made contact with the beam. His hand was also in front of him. So that first thing it should have hit was the chakra covered arm.

Unless the beam didn't actually make contact with Naruto at first, and went above him. Then he ran into it and made contact with his arm. Which is what I said probably happened from what the video shows.

I think Kishi just wanted to show the other form of the GWRE, not only the blade one.
