Physical strength: Mitsuri

- was said to be interchangeable in physical strength but we found out that she was holding back and she's marked here so she scales much higher bc base Mitsuri (not holding back) > Rengoku in physical strength and mark increases her strength 2x / 100x (stated by Tanjiro) 

- Here's proof that it's true: (it does say "These guys put up a good fight" here but it does indeed say "interchangeable" I just got too lazy)

- she even has statements to have more physical strength in base:

Lifting strength: Mitsuri

- shown above

Grip strength: Mitsuri

- she logically needs more grip strength bc:

1. Her sword is much longer therefore heavier than Rengoku's sword

2. Her sword swings around at an extremely fast speed and she needs to grab it very tightly so it doesn't go flying

Piercing strength: Rengoku

- non of them really showed this but I don't think Mitsuri can pierce (I define pierce strength as stabbing strength)

Overall strength: Mitsuri

- More strength points

Running speed: Rengoku

Combat speed: Mitsuri

- this is her cutting through lightning after just waking up + base + holding back:

- this is her slashing through Zohakuten's BDA while still in base:

- this is her slashing through Zohakuten's attacks, making him panic with mark

Technique speed: Mitsuri

- this is her effortlessly slashing through Zohakuten's BDA while legit talking + base + holding back:

- this is her slashing through Zohakuten's BDA again pretty much immediately in base + holding back:

- More feats (this is her in base btw and I'm pretty sure also holding back):

(Oh wait I think this was supposed to be before the feat before this one but whatever-

- statements:

- Her hitting Muzan while in base + not really fresh:

- If you still disagree, I don't know what to tell ya

Reaction speed: Mitsuri

- This is her tensing her muscles right before a shockwave BDA attack:

- This is her dodging Muzan in base:

- And her reacting to Zohakuten's BDA even in base + holding back + talking (all shown way above)

Attack speed: Mitsuri

- Mitsuri attacking Muzan while falling down + breaking the wall at the same time (shown in the technique speed category)

Overall speed: Mitsuri

Durability: Mitsuri

- stated to have 8 times the durability of a human + mark increasing your physics

- Mitsuri tanked a full on shockwave hit from Zohakuten (shown in the reaction speed category)

Reflexes: Mitsuri

- shown in the reaction speed category

Skills: Mitsuri

- passed final selection in 6 months while holding back

- her sword

- created her own breath style and mastered it

Agility: Mitsuri

- Mitsuri bounced off walls in the infinity castle arc and flipped over a wall mid air

IQ: Rengoku

- self explanatory

B. IQ: Mitsuri

- Mitsuri figured out Nakime's BDA in a short period of time even before Iguro

- Mitsuri trying to think of a plan in the middle of fighting Muzan (The picture isn't working rn for some reason but I'll show you it when it works (Mitsuri was thinking about pinning Muzan and more but I can't really remember)

Offense: Mitsuri

- Mitsuri easily cutting through Zohakuten's BDA in base + holding back + talking (shown in technique speed category)

Endurance: Mitsuri

- Mitsuri being seriously injured yet ripping Muzan's arm off with her bare hands in the middle of Muzan attacking Iguro and Tanjiro:

- then got both her limbs cut off yet still died due to blood loss

Feats: Mitsuri

- self explanatory with all these feats I stated

- Here's something:

read the last paragraph: it states that his arms are very hard to read and very hard to reach but Mitsuri did that with ease + in base + very much injured

Winner: Mitsuri, low diff

God, I'm so tired now lol
