-Taiyo Yozakura vs Tanjiro Kamado-

[NikHelton]

• Speed Equalized;
• Taiyo (Blooming) - 318 Kilotons of TNT and Class G;
• Tanjiro (Post-Sun Breathing Mastery) - At least 117 Kilotons of TNT and Class 50;
• Both have all their own equipment
• Place: Aokigahara Forest

 

[CastoriceTheFifth]

Just a heads up for everyone that Tanjiro massively upscale his ap value from Upper Moon 4

Same as Taiyo

Although could you describe Tanjiro's chain to me? He scales to Akaza, but he hasn't been shown to be tougher than Zohakuten. Muzan has also taken damage from all the stopples. Yes, it's above 4 Moon, but I didn't say it was a huge amount

 

[Jackof_noTrades068]

Since this thread has kinda? Happened before. I have a couple questions to ask?
Also due to both having all the equipment, somethings should be taken into consideration

Does Taiyo even have the right to withstand Tanjiro's battle spirit this time? Since this is a stronger key of Tanjiro, or would Tanjiro's see through world mean he has none since Akaza can't pick up battle spirit from him?

I know Tanjiro upscales from his ap value, but Taiyo post timeskip with hardening upscales so much from his ap value that Taiyo's own sword slashes do "zero damage" (no blood, not even scratches drawn when Taiyo charged into the guy head on) to a guy using an off brand version of his own hardening, who he can even hurt with generic punches when that opponent did not use hardening (And Taiyo can maintain hardening for hours). So would Tanjiro be able to do non superficial damage early on in the battle with his sword techniques? This is kinda made worse by Taiyo's attire being blade resistant. And even worse since Taiyo has equipment, which includes Kengo's fake skins, which are basically armor and can even break small blades having their own damage reduction. Albeit only for his bare skin and face.

While Tanjiro resists poison manip, its less a true resistance and more about slowing circulation. Tanjiro resisting sleep manip is also more so about supernatural dream worlds, his paralysis manip resist also isnt really a matter of poison either but battle spirit. So since Taiyo has his equipment. Whats stopping Taiyo from incapping with good knight whale needles, Blight spider neurotoxin or his sleeping gas sprays? Which work on Yozakuras who resist sleep and paralysis inducement via biological means while outright resisting poison.

Small thing. Taiyo would have Nanao's vitality booster, so Taiyo can reset his stamina back to full if he uses it on himself

Taiyo's lifting strength is a lot higher, so if Taiyo and Tanjiro have their blades locked against each other, whats stopping Taiyo from just trying to force him to the ground from that position (Class G vs Class 50)? Or would Tanjiro use his precog to immediately try jumping back if he sees this happening

Are there even any clear counters to the see through world? Iirc its so precise that Tanjiro would be able to see Taiyo's slightest muscle movements when he's going for attacks in slo mo (Since he saw Marked Giyuu vs Akaza in slow mo, which is better than Taiyo's own perception amplification). Which is pretty different to Taiyo's which is only really a result of his battle iq and he'd need to learn how his opponent fights to start predicting. Pretty sure only Muzan was able to stop Tanjiro from using it 24/7. Depending on the see through world Taiyo may not even be able to actually fight or land hits on Tanjiro, which could make this a stomp?

Tanjiro has a stamina edge just like the previous thread, that doesn't need to be elaborated on.

btw OP, restrict true spring Blooming, or Tanjiro can't scratch Taiyo then gets one shotted by any of Taiyo's kilometer wide AOEs the instant Taiyo powers up. Cause Taiyo has been willing to use that form on an enemy he simply finds really annoying and who he was stalemating in base.

 

[NikHelton]

Since this thread has kinda? Happened before. I have a couple questions to ask?
Also due to both having all the equipment, somethings should be taken into consideration

Taiyo now has an AP advantage, is more skilled and skilled than in previous keys, and has access to all equipment

Does Taiyo even have the right to withstand Tanjiro's battle spirit this time? Since this is a stronger key of Tanjiro, or would Tanjiro's see through world mean he has none since Akaza can't pick up battle spirit from him?

I don't remember a single case where this worked on an equal in strength and mentally strong opponent. In order to resist this - it is enough to have a strong willpower.

I know Tanjiro upscales from his ap value, but Taiyo post timeskip with hardening upscales so much from his ap value that Taiyo's own sword slashes do "zero damage" (no blood, not even scratches drawn when Taiyo charged into the guy head on) to a guy using an off brand version of his own hardening, who he can even hurt with generic punches when that opponent did not use hardening (And Taiyo can maintain hardening for hours).

Yes, this is a good point for wincon

While Tanjiro resists poison manip, its less a true resistance and more about slowing circulation. Tanjiro resisting sleep manip is also more so about supernatural dream worlds, his paralysis manip resist also isnt really a matter of poison either but battle spirit. So since Taiyo has his equipment. Whats stopping Taiyo from incapping with good knight whale needles, Blight spider neurotoxin or his sleeping gas sprays? Which work on Yozakuras who resist sleep and paralysis inducement via biological means while outright resisting poison.

I didn't quite get it. The Ekadzura resist tranquilizers and poisons through their biology, but they can't resist Taiyo's equipment?

Also, will holding your breath protect you from the paralyzing gas? Tanjiro can hold his breath for a long time

Small thing. Taiyo would have Nanao's vitality booster, so Taiyo can reset his stamina back to full if he uses it on himself

Good

Taiyo's lifting strength is a lot higher, so if Taiyo and Tanjiro have their blades locked against each other, whats stopping Taiyo from just trying to force him to the ground from that position (Class G vs Class 50)? Or would Tanjiro use his precog to immediately try jumping back if he sees this happening

Tanjiro will be able to see that they are superior, but will he be able to understand that the difference is so colossal?

Also, considering that we have both AP and LS differences, Taiyo's strikes will cause direct damage to Tanjiro if he tries to block them, and Taiyo can very easily break his limbs and tear his joints.

By the way, what about aiki?

Are there even any clear counters to the see through world? Iirc its so precise that Tanjiro would be able to see Taiyo's slightest muscle movements when he's going for attacks in slo mo (Since he saw Marked Giyuu vs Akaza in slow mo, which is better than Taiyo's own perception amplification). Which is pretty different to Taiyo's which is only really a result of his battle iq and he'd need to learn how his opponent fights to start predicting. Pretty sure only Muzan was able to stop Tanjiro from using it 24/7. Depending on the see through world Taiyo may not even be able to actually fight or land hits on Tanjiro, which could make this a stomp?

As far as I remember, Taiyo has stat boosters, resistance to analytical prediction, and can also change the trajectory of Momo's bullet, which Tanjiro can't track.

Furthermore, seeing the enemy's attacks doesn't give you a guaranteed victory when you still need to make contact with them to win, and they have powerful durability, additional equipment, and superior strength.

Tanjiro has a stamina edge just like the previous thread, that doesn't need to be elaborated on.

Fact

btw OP, restrict true spring Blooming, or Tanjiro can't scratch Taiyo then gets one shotted by any of Taiyo's kilometer wide AOEs the instant Taiyo powers up. Cause Taiyo has been willing to use that form on an enemy he simply finds really annoying and who he was stalemating in base.

The match uses their High 7-C keys.

I didn't quite get it. The Ekadzura resist tranquilizers and poisons through their biology, but they can't resist Taiyo's equipment?

Also, will holding your breath protect you from the paralyzing gas? Tanjiro can hold his breath for a long time

This is just cause a lot of the Yozakura's equipment they use is as potent as or stronger their resistances. (For example Shinzo can resist common paralysis toxins, Nanao Yozakura's paralyzing gas as well as muscle relaxants with no issues, but Good night whale needles paralyze Shinzo if you can inject him with like 10 of them, which Taiyo actually had that amount on him)
In the Yozakura verse a lot of spies worth their salt resist those things. And the Yozakura's don't get their all resistances from their custom equipment, but often other things, besides their gear which possesses sleep hax, those they resist them all. Some Yozakura's resist even more than others, but if they do it goes on their own pages, like Kyoichiro's sleep and paralysis resistance feats.
The gear descriptions go in more detail, so does the spy resistances section of the Yozakura physiology page.

With Holding his breath, yeah that can work, but the whole demon slayer power system does rely on breathing to produce techniques, so he'd temporarily be unable to use special moves or his dancing flash speed amp if he's a spot paralysis gas has been dropped in until he gets out of there or the gas disperses.

Tanjiro will be able to see that they are superior, but will he be able to understand that the difference is so colossal?

Also, considering that we have both AP and LS differences, Taiyo's strikes will cause direct damage to Tanjiro if he tries to block them, and Taiyo can very easily break his limbs and tear his joints.

By the way, what about aiki?

Arguably Tanjiro could realize the gap is collosal with the see through world, since he can see Taiyo's muscle structure and all that like an X-Ray. So hard maybe he'd look at him and instantly realize he's a physical monster and that he's better trying to fight nimbly than head on.

Noted

When it comes to Aiki (Aikido). It's the main way Futaba Yozakura Fights. Taiyo does not have the abilities Futaba and Asa have via Aikido knowledge, he simply understands the fundamental principles behind attack reflecting, parrying attacks from a stronger adversary. As well as escaping the grip of someone with much higher lifting strength via accepting the flow of said grabs. Tanjiro's sort of got a similar thing he learnt during the Entertainment district arc vs Gyutaro though, mainly in the context of parries.
Something Taiyo does have over Futaba is him achieving equal or better performance against Asa when Futaba had Shion, Shinzo and Nanao backing her up when she fought Asa, while Taiyo fought the guy alone in a 1 on 1.

As far as I remember, Taiyo has stat boosters, resistance to analytical prediction, and can also change the trajectory of Momo's bullet, which Tanjiro can't track.

Furthermore, seeing the enemy's attacks doesn't give you a guaranteed victory when you still need to make contact with them to win, and they have powerful durability, additional equipment, and superior strength.

Fair points I suppose, although I specifically don't think Momo's bullet would be the most relevant here, since Tanjiro's strength amounts to him just being really strong (rather than some special physiology that's not a normal human) + breathing techniques which are just techniques. Tanjiro ain't like a Yozakura or a quirk user from MHA. I'm not even sure if the regen negation would work on Tanjiro since Tanjiro's just breathing to keep wounds closed, rather than having a truly fast healing factor (But its only low regen anyway, so who really cares). TLDR Momo's bullet would just be a bullet wound.
Tanjiro does also have amps of his own like repetitive actions and dancing flash.

Speaking of Regen though, this question is more for Demon slayer supporters, but is the basis of regen negation (while it is High-Mid) for breath of the sun and red katanas heat? if so I guess Taiyo's heat resistances ignores that?

The match uses their High 7-C keys.

Post-Timeskip Taiyo has no keys, just transformations, so you usually gotta specify in OP that a form is restricted. It's sort of like if you had a match with Dark Hero Arc 30% Deku but you don't restrict 100%.

I believe its heat yeah, one which burns to the cellular level coupled with demons being weak to nichirin. If Taiyo has demonstrated good enough heat resistance, then he should be alright?? idk much about him tho, so you can clarify that.

 

[Jackof_noTrades068]

Yeah sure.
Taiyo only has low mid regeneration
But his heat resistance is that with hardening he can withstand resist the heat of attacks that reduce concrete and steel to vapor during his pre Timeskip era (minor bonus feat of being able to vaporize people with his sword attacks too back then). He’s currently rated at 3000C in heat resistance
While the Demon slayer verse doesn’t appear to have heat ratings

Taiyo’s hardening also operates at the cellular level. So his heat resistance would be that precise too

 

[Catbowtie]

Is Taiyo trying to kill Tanjiro or nah?

 

[Jackof_noTrades068]

Is Taiyo trying to kill Tanjiro or nah?

Under an SBA mentality
Post Timeskip Taiyo is one who could fight to kill (as he actually did kill Asa, but sorta needed to given the guy’s regeneration and how he was incapable of knocking him out or taking him alive)

But he’d start out by trying to subdue/incapacitate since Tanjiro to him wouldn’t come across as anything beyond a really strong guy who happens to be a swordsman, if he exhausts his options on that front he’d try to kill him.

Taiyo uses lethal force when lethal force is deemed necessary.

 

[Catbowtie]

I hate Demon Hunter matches where they fight other humans...

Tanjiro isn't the type of guy to try to swing his sword and actually attack Taiyo. Taiyo is a human and Tanjiro will sense that. Tanjiro doesn't fight humans in-character. If you want them to fight, as in actually fight, you gotta alter Tanjiro's State of Mind to have him not care about Taiyo being a human.

Or Tanjiro wins via Social Influencing GGs

• Social Influencing (Charisma; Forced the naturally aggressive Genya to work with him just with the innocence of his eyes)

 

[Jackof_noTrades068]

Or Tanjiro wins via Social Influencing GGs

Ah yes the classic the fight ends in them becoming friends

 

[Catbowtie]

I think it's a valid win condition because Tanjiro has Social Influencing

 

[Epyriel]

Don’t think too much changes from the main deciding factor from last time being speed amps:

Taiyo:
-1 Blitz Gap Speed Amp
-1 Blitz Gap Equivalent Analytic Prediction + Instinctive Reaction
-Higher AP/Durability
-AoE Attacks

vs

Tanjiro
-2 Stacked Blitz Gap Speed Amps
-1 Blitz Gap Equivalent Precognition
-Better Stamina
-Reactive Accelerated Development

As before, I think Tanjiro can probably drag this out with better speed and stamina enough to gain victory (with some difficulty) despite Taiyo being more durable. So for now I’ll vote Tanjiro.

 

[Catbowtie]

Tanjiro
-2 Stacked Blitz Gap Speed Amps

You forgot Rage Power, Repetitive Action, Dancing Flash, Transparent World, and Tanjiro spamming Thirteenth Form for more stat amps.

 

[Epyriel]

Counted breathing forms as 1 stacked speed amp, but yeah I will add one for TW since we are using a key that has that this time around. Can’t use Rage Power without him being bloodlusted in the OP.

 

[Jackof_noTrades068]

I think it's a valid win condition because Tanjiro has Social Influencing

Not really cause Taiyo cause SBA mentality means Taiyo thinks if he loses this severe consequences would follow in some shape or form.
So he'd just assume Tanjiro is lying when he tries to talk Taiyo out of fighting him (Which is kinda ironic, cause Tanjiro actually trying to lie would be clear as day to Taiyo since Tanjiro's so bad at it). I mean, Taiyo's a spy after all, deception is something he's used to facing, and there are spies in the Yozakura verse good enough to fool the intent sensing of a Yozakura such as Hulang.

Don’t think too much changes from the main deciding factor from last time being speed amps:

Taiyo:
-1 Blitz Gap Speed Amp
-1 Blitz Gap Equivalent Analytic Prediction + Instinctive Reaction
-Higher AP/Durability
-AoE Attacks

vs

Tanjiro
-3 Stacked Blitz Gap Speed Amps
-1 Blitz Gap Equivalent Precognition
-Better Stamina
-Reactive Accelerated Development

As before, I think Tanjiro can probably drag this out with better speed and stamina enough to gain victory (with some difficulty) despite Taiyo being more durable. So for now I’ll vote Tanjiro.

Didn't realize Tanjiro's up to 3-4 stacks in this key, didn't realize the new amps could also stack
Honestly doesn't seem like Taiyo tags Tanjiro ever besides his tens of meters wide Yae electric blasts, but with a speed gap this severe, he'd probably just see Taiyo switching to the gun version of his weapon and dash back.
So it seems more like this match is just Tanjiro hacking on a guy he can barely damage until Taiyo eventually gets exhausted (although this will take hours at least, Tanjiro does have the stamina for this)
Doesn't seem like Taiyo has feasible wincons in a scenario such as this.

I will add that Taiyo's prediction has improved in this key now. It's not the standard blitz diff or speed gap based quantification. But unlike last thread (where while Taiyo has feats against Kyoichiro and his own feats, he'd still get skill stomped two times over by either Momo or Kyoichiro back then) Taiyo is Post Timeskip Kyoichiro's equal in skill at this point, who before the timeskip, outskilled Momo Yozakura on two occasions. Also considering him to be unimpressive and sloppy since he could read his next moves. While Momo had precog of this degree. Not the most sure on how that interacts with the speed gap, or if itd prevent the matchup from being one where Tanjiro is untouchable (making it fair instead of stompish)

Perhaps OP could try Kyoichiro Yozakura (not futaba yozakura though, she's a really bad matchup for demon slayers) if they don't want something so similar to the old match

Tanjiro FRA

I don't remember them overlapping at all. Maybe the transparent world and some of the techniques, but that could be a consequence of their combination, but it doesn't mean that it's now a double blitz.

Taiyo's stamina also allows him to fight for hours. Surely he won't find a way to use Momo Bullet or Steel Spider to pin Tanjiro down or simply take away his weapons?

Momo Bullet won't take away Tanjiro's abilities, but it could be a headshot he can't dodge

Doesn't seem like Taiyo has feasible wincons in a scenario such as this.

BIQ + equipment + stats + perception bypass

Tanjiro also won't be able to analyze Taiyo's strength through the transparent world. He will see that his opponent is strong and has developed muscles. However, his anatomy is the same as a human. He can't look at his enemy and say "Oh my. His LS is 729358146 times greater than mine."

 

[NikHelton]

Vote for Taiyo

This is true. Honestly with this matchup i'd say that it depends on Taiyo's ability to get a hold of Tanjiro (or likely even his blade).
Once, then he shouldn't have trouble restraining or knocking out Taiyo since unlike last match, Taiyo has an extra damage reduction tool, and actually has almost double AP at the start (while last thread had equal AP but higher dura). I'm just unsure on Taiyo's opportunity to get said opportunity

Momo's bullet headshot with its stealthy properties though is a valid wincon

I don't remember them overlapping at all. Maybe the transparent world and some of the techniques, but that could be a consequence of their combination, but it doesn't mean that it's now a double blitz.

I'd probably wait for Demon Slayer supporters to comment more on this, if no further comments are given in regard to speed amp interaction I'd vote for Taiyo. For now though I'll hold out

We’ve seen pretty much all of them stack at some point or another.

For some examples:

• With BTs alone was getting blitzed by the Type Zero, with BTs + Precognition he outsped and defeated it
• With BTs alone was getting badly blitzed by Gyutaro, with BTs + Mark he caught up to Gyutaro
• With BTs + Mark + Precognition was relative to Akaza, with BTs + Mark + Precognition + TW he badly blitzed Akaza

Honestly, I'm confused about how the boosters work.

It turns out that Tanjiro, with the speed leveled out, is much more dangerous than Kokushibo and Douma

 

[Catbowtie]

Not really.

Kokushibo can do much of the same thing.

Doma can make it a 6v1 very quickly.

Voting Tanjiro then, he's fast enough to where Taiyo's kit becomes unusable cause he just can't tag him

Ain’t that a Stomp or nah?

 

[Jackof_noTrades068]

Ain’t that a Stomp or nah?

It’s still considered a stomp if the losing character despite having win cons it’s literally impossible for them to use em right?
Then yeah it is

Last thread Tanjiro had less speed amps so it was more reasonable to say Taiyo could catch a win in several ways but Tanjiro’s being more consistent. (See Through world is especially a problem here)

 

[NikHelton]

Ain’t that a Stomp or nah?

Wait, doesn't SBM already include an activated mark, sun breath, and a transparent world from the start?

 

[Jackof_noTrades068]

Goat

 

[NikHelton]

Nah.
Only Mark is constantly activated

Wasn't his transparent world active when he fully unlocked the sun's breath?

I mean, he had high speed precisely because he had the sun's breath and the mark at that time. At the very least, these boosters are included in the base speed of his key and are subject to the equation. As a result, the only boost left is TW

If I remember correctly. Even while standing still not using a breathing technique Taiyo viewed Giyuu and Akaza as very slow. Or when he dodged that one swipe at his torso from Akaza there were no breathing techniques involved. With TW not being a standard perception blitz style gap either but being a lot bigger

This is a good point, since the Mark is considered in his base form in this key we are back down to the same number of speed amps as last time.

[Jackof_noTrades068]

I see
In that case I’d actually vote Taiyo then (high difficulty)
Taiyo will be the slower fighter. And he shouldn’t approach this from a POV of just trying to conventionally sword fight Tanjiro. It’s not an approach to this fight worth trying. And Taiyo will learn that very fast
But with stuff like all his gear, the fact that at the start he can likely shrug off Tanjiro’s slashes. Numerous types of poisonous and paralysis gas (forcing Tanjiro to hold his breath temporarily unless Tanjiro feels like throwing), steel spider threads to catch Tanjiro off guard and a few other things.
Kengo’s fake skin is also resistant against blades that Taiyo can view baiting Tanjiro into swinging at him then grabbing the sword before he pulls back or something of the sort (Thanks to the LS gap this could work if it occurs)
I can also see scenarios where Taiyo wins via bombardments of big attacks (as his AOE range is tens of meters now with First form Yae)

There are also cases Tanjiro can win, but I’m leaning more on Taiyo.

Just gonna mention this now. Holding his breath canonically gives him a blitz amp and a strong ap buff.



Tanjiro would also last longer doing this since this was like season 2 Tanjiro

This is basically counted as part of his Rage Power which wouldn’t be applicable since he isn’t bloodlusted in the OP.
