Profil Sembang Terbalik Kny goes into a convention?!

Soo, all the hashiras (and Tanjiro,nezuko,inosuke and zenitsu) somehow come into the real world and end up at a anime (cosplay) convention. Hundreds of ppl r there cosplaying characters from Mha,Kny,hxh,kcm,one piece,death note,danganronpa,jba,nana,their own oc’s, and other anime’s. They also kinda wonder why ppl are dressed up as them and just walk around to look at everything.
