The Weirdness I Took in Became My Blood Bar

A strange invasion turns the world upside down. Others rely on luck to survive, but I rely on my sister to survive. My sister is the walking doomsday, and I am the only switch to the doomsday. Binding my sister, I have immortality. Containing the weird, I can borrow all their power. The memory-eating ghost allows me to read my memories, and the dream tapir allows me to sneak into my dreams. I built a shelter underground, and every cell was my arsenal of weapons. MAD wants to control us? Let me first ask if I can answer the sixteen containment cards.
