Introduction
As it stands, the speed ratings for Demon Slayer are a bit of a mess. About half the ratings reference removed calcs (Tanjiro Dodges Point Blank Demon Attack and Zenitsu Blitzes Lightning) and the other half are based on a heavily criticized calc (Muichiro Cuts Ten Thousand Fish).
In light of this, I wish to propose a batch of revisions to swap out them out with five other accepted calcs (Mitsuri Dodges Lightning, Tengen Cuts Bombs, Tanjiro Dodges Lightning, Tanjiro’s Flowing Dance, and Tanjiro Dodges Swamp Demon). I will also use the chance to brush up some of the justifications on the existing profiles, the full list of such proposed revisions can be found here.
As it stands, much of the verse stands at Massively Hypersonic derived from Muichiro cutting ten thousand fish in SSV, however this calc has been heavily contested thanks to how many assumptions you need to weigh based on how many cuts he is actually making which depends on assumptions about his reach, the angle of his sweeps, and how fast the fish are moving. To but it simply, it is a little messy.
However, in line with Hantengu’s lightning being accepted as real lightning, we now have a good number of replacements (and even some upgrades) to substitute in its place to maintain the verse’s status as a lightning timer (which does fit nicely with how incredibly frequently its characters are described as fast as lightning, which is now backed up by more substantive calculations).
Demon Slayer Speed Scaling Context
First, it should be noted is that there is a significant gulf between the travel speed, base combat speed, and breathing technique combat speed of demon slayers. For example, Tanjiro initially struggles against the speed of the temaris when fighting Susamaru, yet then later in the same sequence utterly blitzes them as if they are completely still when using Water Breathing: Flowing Dance. Meanwhile in travel speed even the Hashira are compared merely to the wind and are relative to their crows, while Tengen is ranked higher than Gyomei despite being relative in combat speed only to UM6 whereas Gyomei could keep up with UM1.
Thus is should be recognized that:
Demon Slayers’ Breathing Technique Speed >> Demons Slayers’ Base Combat Speed >> Demon Slayers’ Travel Speed
So characters who would scale to a given demon slayer’s base combat speed (like Susamaru being relative to Base UR Tanjiro), would in no way necessitate scaling to their maximum speed while in the apex of their breathing technique (as in Susamaru getting utterly blitzed by UR Tanjiro with Flowing Dance). It should be noted that this difference is especially drastic during the Unwavering Resolve Arc where the main characters have not unlocked Total Concentration Breathing: Constant.
Proposed Changes:
Scaling From Base UR Tanjiro (Mach 0.85):
Currently all of the UR Demons are scaled from a removed clac. In its place, those that only scale to UR Tanjiro’s base speed and cannot keep up with his technique speed (and thus do not qualify to scale off of the flowing dance calc), must all be downgraded to the next best calc based off of his base speed.
