(YOU ARE SANEMI)

Genya wanted to talk to you, but you ignored him. Tanjiro watched the interaction from behind a wall

Genya: Wait! I...I just wanted to tell you something!

You stop in your tracks, waiting for Genya to say something

Genya: I...I ate a demon...I eat demons-

He didn´t get any farther because you suddenly disappeared. But then you shot out at Genya, fingers heading towards Genya´s eyes, aiming to blind him. But Tanjiro quickly tackled Genya out of the way before you could get to him
