I wish I could stay.

I do.

And I'll never forget you.

No matter what, you will always be in my heart.

I promise you this:

I will make you human again.

Unless...

Am I no good?

Will Nezuko die just like this?

With that fragile resolve of yours, you can't protect your sister or heal her.

And you'll never get revenge for what happened to your family.

You're slow, weak, and immature.

That's not what I'd call a demon slayer.

He's far too kind and far too indecisive.

He stands against a demon, yet the scent of kindness remains.

This boy will never make it.

These two are different.

I'm asking for you to train this boy.

If I'm not mistaken, this will all make sense one day.

I'm giving it all I've got, every day, except I'm not getting anywhere.

I can't...

I don't think I can do it.

You can!

If you are feeling disheartened,

that you are somehow not enough,

set your heart ablaze.

You did just great.

Never forget about this.

Well done, Tanjiro.

Truly remarkable.

I hear that you've mastered Total Concentration: Constant.

I have!

You should keep at it.

Tomioka...

Urokodaki...

There are the others, too.

They've all gone out and risked their lives on our behalf.

You must continue to grow.

Feel the pure rage of being unable to forgive.

Let it be what gives you the strength to take action.

There's nowhere else to go but forward!

I know I have what it takes!

I will not yield!

What you did...

I don't know how to ever repay you.

And I'll never forget you.

Thank you.
