Pick which one your with: Port Mafia(PM),Armed Detective Agency (ADA),Decay of Angels(DOA),Hunting Dogs or even the Guild

You were walking with Dazai and Chuuya, whom were arguing, and then the three of you saw a portal. People came out of it, they were Tanjiro, Nezuko, Zenitsu, Inosuke, Kanao and Genya along with the Hashiras Gyomei, Tengen, Rengoku, Shinobu, Giyu, Mitsuri, Muichiro, Obanai and Sanemi. (Add the Upper Moons if you want to)

Dazai looks at them with a confused expression

Dazai: Oh?who are those people?
