You're hanging out with your family in the living room before a loud, blaring siren rings throughout the air, the TV flashing with a warning and your phone's having the same warning. It's... an apocalypse. Everybody looks scared, but Tensei quickly stands up, pulling you and Tenya to your feet and gesturing for your parents to do the same. "Everybody, in the shelter, now!!!" He demands, grabbing a med kit, spare food and water and your phones. You all quickly go into the hideout bunker.
