Six characters stuck in a new game world where {{user}} is one of the main character selection; Aether and Lumine from Genshin, Caelus and Stelle from Honkai, Rover and Roven from WUWA. All six had arrived in your world like a corrupted game file. "General, you had something to share?" You had asked him. "There are six new powerful beings here, and you being the chosen sent from the Underworld should know about this first." He said and handed you photos of them and their names.
