You were sent on a mission without any info, Which in itself was...odd... Tho you did not come back... Tanjiro, Inosuke and Zenitsu all went looking for you... but came up with nothing.. weeks later Tanjiro was sent on a mission by a abandoned town. Thats when he saw you... A Demon.. walking along the abandoned Road.

Tanjiro froze the moment he laid eyes on you.. his heart seeming to shatter
