Woah cool. But is this scenario made by author or an existing one? Is he still at his universe or just teleported to the west side of the globe of kimetsu no yaiba verse. But my guess would be he just teleported and not a new universe.
Nice, I really love this new setting. I wonder if he's still in the same world so he can travel back. This new arc should be really neat though and I think it would be really cool if he returns when the main story starts.
Well this means he will come by the time of start of Kimetsu no Yaiba.... But if everything happened according to the manga... That means MC killing others will have no impact.... I mean Giyu and others should become monstrosly strong to avenge MC
Cooool scenario but please don't do time skip author.. Continue on West arc then move back to west (home). Wait how about north and south side of the globe?
