Rescuers (2).

"You guys are leaving again?!" One of the people, a woman, sitting on the ground said to Jenny as they walked towards the door of the room.

This room is an underground safe room that for some unknown reason, exists beneath the gymnasium. When the apocalypse happened, the people in the gymnasium were one of the first that were attacked by the devils that fell from the sky. 

 To avoid getting killed, Jenny, who for some reason or the other, was able to locate this hidden room, managed to rescue a majority of the people who were within the gymnasium at the time the chaos began alongside Li, Sue, and Stan.

Li and Sue were siblings who had been close family friends with Jenny since they were kids. Stan, on the other hand, had been Li's best friend since they were little, so they were all very familiar with each other.
