It's the Shinjuku Showdown Arc. Gojo just got killed and sliced in two halves by Sukuna,Utahime almost lost all hope

Utahime: Watching with extreme worry

Suddenly Substitute Shinigami Ichigo Kurosaki steps out of a Senkaimon gate (it malfunctioned and sent them to this universe instead of their designated location)with Shinigami Rukia Kuchiki and Renji Abarai along with Urahara Kisuke,Orihime and You a shinigami like them(Orihime isn't Shinigami)

Utahime: looks at you guys in surprise and hope H-huh? Who are you guys? I've never seen you around before She asks you guys

Now y'all can fight Sukuna or Kenjaku or do whatever you want

You may be Visored if you want to (Also Grimmjow is watching but he has no bad intentions..)
