Guys, here's my amateur translation of the full scans as a Korean (I'll try and be quicker next time):
<The demon-turned Tanjiro! At that moment-…>
Chapter 202 – Let’s go back
Nezuko: Onii-chan (brother)
I’m sorry
Sorry that I’ve known nothing so far
I made you deal with everything on your own
Why is it always you that has to have it difficult
Why is it always the hardworking, kind people
Who are trampled on?
It’s too degrading, don’t lose
Hold out for a little longer
You can’t become a demon
Let’s go back,
Okay?
Let’s go back home
Zenitsu: Tanjiro let go!
It’s Nezuko
She went back to being a human, she’s back
She’ll die if you keep going like this!!
She’s calling you onii-chan!!
Inosuke: I told you to stop!!
Stop going ‘Kyaak kyaak’ (Korean sound effect for demon sounds I guess lol)
Don’t let Nezuko-chan get hurt
You’re not… not that type of bastard
You used to be so kind…!!
Bring back the original Tanjiro!!!
Nezuko: Euugh…
Zenitsu: coughing up blood sounds (Kakushi – aahhhh…)
Giyuu: Ugh
Ugh
Nezuko: Onii-chan don’t lose
Onii chan….!!!
Tanjiro: (demon breathing sounds, like ‘hurgh, hurgh’)
Zenitsu: No!!
Giyuu: Water Breathing
Fourth Form:
Striking Tide!!
He bit Nezuko!! He recognizes the taste of blood
Now that’s wrong..!!
Quickly!! We need to kill Tanjiro quickly before he kills anyone
But…
Neither red swords nor the sunlight have any effect on Tanjiro
There’s no way of killing him…!!
!!
Nezuko: Don’t kill anyone!!
Tanjiro/onii-chan please!!
Stop!!
Zenitsu: Uahh Nezuko-chan!!
Nezuko: No!!
Stop doing that!!
Zenitsu: I hate it, I hate it, get off of Nezuko-chan!!
Tanjiro please stop!!
Inosuke: Tan-
Jiro…
Nezu…
Giyuu: Why won’t he kill Nezuko?
There’s blood-shedding food right in front of his eyes
Why did his attack just now miss her?
Are you resisting too, Tanjiro?
If only I can locate Tanjiro’s ego…!!
But will I be able to pull off a miracle like that…!!
Yushiro: This is crazy, crazy
How did this happen…!!
That bastard Muzan…!!
Even after he dies he’s still a pain in the neck for others
Damn it!!
I can’t go over there because of the sunlight…!!
Under the sun, my talismans become dust
There’s nothing I can do
!?
Kanao: Heok,
Heok (I don’t know the equivalent sfx in English, just pronounce that word literally to figure it out)
Tanjiro…
Nezuko-chan…
I feel bad but…
Haah…
Haah…
It didn’t break…
I can use it…
Shinobu: I’ll entrust this to you Kanao
Use this in case the medicine used on Nezuko (to turn her back to human) wasn’t enough
It’s made from Wisteria flowers…
Tamayo made 3 antidotes to turn demons back to human
There’s no need for anything else now
‘That person’ is
An amazing person
I respect her
Kanao: The one eye I have left
It was for this situation/now, wasn’t it
Sister (referring to Shinobu)
It hasn’t been long since he’s become a demon
If it’s now at least
With even one eye
I’ll be able to dodge Tanjiro’s attacks.
Breath of Flower/Flower Breathing, Final Form:
Equinoctial Vermillion Eye
!?
Giyuu: Kochou’s…!! (he was about to say Kochou’s tsuguko)
Kanao: You mustn’t be like this Tanjiro
Come back quickly
How can you make Nezuko cry….
Tanjiro: Nezuko…
Nezuko: Kanao-chan
Credits: The sorrowful plea that pierces the body-…
(Someone posted a translation on 4chan earlier but meh here's my one anyway)
