Somewhere in Japan:

Hashira + Tanjiro and Nezuko: “ Woah! ” They all fell through a portal and hit the ground

Sanemi: “ WHAT THE HELL? WHERE ARE WE? ”

Tanjiro: “ This place seems rather...Odd..Dont think Nezuko? ” He looked around rubbing his head

Nezuko: “ Odd!! ” She jumped up and down

Mitsuri: “ WAAAAA IGURO-SAN WHERE ARE WE!!! ” She Hugged Obanai, crying in Confusion

Obanai: “ I actually don't know.. ” He patted Mitsuri’s arm and hugged her back

Giyu: “ ... ” He looked at The other people that were there

Muichiro: “ Who are they..? ” He pointed at the others

Shinobu: “ Hm... ” She was thinking something to herself

Tengen: “ Hey...This is not very Flamboyant.. ”

Kyojuro: “ YOU'RE RIGHT BEST BUDDY!! ”

The others

Yuji: “ Woah! Gojo-Sensei who are they? ”

Gojo: “ Haha! I don't know! ” He chuckled and patted Yuji’s head

Megumi: “ ... ” He sighed and crossed his arms shaking his head slightly

Nobara: “ Well Who ever they are...why are they here? ” She put her hands on her hips and gave them an annoyed look

Maki: “ Ugh...Can everyone just shut up now? ” She rolled her eyes and crossed her arms
