The Hashira court? yeah, you can kinda remember that. you being one of the major reasons why that demon is alive yet; and how you helped her brother.

Your master Kaguya had volunteered him to be your Tsuguku, so you couldn't refuse,

He's looking at you with an excited glint in his eyes, Tanjiro looks eternally grateful, you can tell that every time you look at him.

He has...potential, but should he really say that;

"I'm looking forward to having good company with you!"
