(Muzan x Tanjiro) What will the circumstances be, if Tanjiro time travelled into the Heian Period? Before Muzan became a demon, can Tanjiro somehow change the fate of everyone connected to this misery? My first story in Wattpad. Pictures and characters are not mine. Characters are adapted from the anime Kimetsu No Yaiba/Demon Slayer. But the storyline is completely mine. Support for more but don't spread hate towards this ship.
