The Big Shot of the Apocalypse

As the younger son of a family made rich by demolition compensation, I usually pick on my little sister, and when trouble comes, my big brother deals with it. I could have coasted through life, so why did the System suddenly choose me? I really don't want to be some chosen one. I dream of being a lazy fish, but the System insists on turning me into a villain. What? Earth will enter the apocalypse in three days? Everyone else's teams are made up of orphans, so they're free to do as they please. But I have a whole family to look after! I'm freaking out! Big bro, good luck. I've got all your gear ready, so go on... Little sis, stop eating! Everyone else is losing weight, so how come you're getting fatter? Doesn't the apocalypse care about appearances? Mom, this is the apocalypse! Stop trying to make me drink soup. Dad, all the chickens, ducks, and geese you raised have mutated.
