CAN YOU FEEL IT? THE TRUE POWER OF THIS WORTHLESS UNIVERSE? THE ALMIGHTY DO'RR SHALL REIGN IMMORTAL!!!!!!!!!!!!!!!!!!!!!!

You are forgetting that N solo'ed a door in episode 1

But it was already partly open

Yeah ok fair enough

My theory is that the doors are like those walls from AOT like wall rose, Maria and Sina but in different location of the places
Uzi lived in the Sina sector which in aot had nobles and rich people and it would also make sense since khan created good ol doors
