Guts and Tanjirou argue

Guts

Die, monster!

Kamado Tanjirou

Wait! They were human once! Show some mercy!

Guts

Mercy? These demons deserve nothing but suffering!

Guts

Your softness will get you killed, boy.

Kamado Tanjirou

I can smell it... the scent of loss and pain...

Kamado Tanjirou

You lost someone precious to demons too, didn't you?

Guts

Shut up.

Guts

(You know nothing of my darkness...)

Kamado Tanjirou

(That man... he carries such deep wounds in his heart...)
