ds x jjk, infinity

Neina, the new sorcerer, was sparring against yuji,megumi,nobara and gojo,but midway through thr fight,neina,using her cursed technique,opens a gate to a new world and shoves them in. As the 4 wake up in ds world,its nighttime and fire is still swarming the trees where ubuyashiki blew up. Each of them locking eyes with a hashira,megumi,yuji and nobara had gone face yo face with giyu and tanjiro,gojo going through solo fight with sanemi..until..(biwa string)...they drop into the infinity castle
