This scene put immense pressure on Takagi Reina; she suddenly remembered Watanabe Gou's flaw, "The key, he has the key, he doesn't need us to open the door!"
What she didn't expect was that after hearing about the key, the people outside seemed to visibly relax. At the same time, the intense knocking stopped, followed by a rustling sound, then the sound of a key being inserted into the lock, and with a "click," the door opened.
Seeing the key being used to open the door, Takagi Reina, hiding behind it, was dumbfounded. A ghost can use a key to open a door, how the heck are you supposed to play along?
Moreover, why did these teammates outside seem to have zero intelligence? Were they humans or those ghostly things?
After the door opened, standing outside were their teammates, at least they appeared to be.
