Kazuha: "What are we supposed to do now?" Scaramouche: "We're doomed." Xiao: "No one is rescuing us, it's been 2 days.." Aether: "It will only take 3 days for us to survive without water." Heizou: "Does anyone have any clue if there's any other survivors in the school?" Venti: "I think everyone turned to zombies.."
