We return to the part where the Hashiras were with Tanjiro, since he had a demon with him. (His sister Nezuko). All the Hashiras were discussing what to do with the two of them.

You were a demon, you were similar to Nezuko. (You didn't eat humans, you fed by sleeping, and you also had a similar power.) The Hashiras saved you, the reason is unknown, but they still grew fond of you. Especially Mitsuri, the Hashira of love. Currently, you were running, Genya was chasing you.
