My name is Yae Tora, just an ordinary person trying to survive the apocalypse. My little sister and I depend on each other. She's been sickly since childhood and can only get around in a wheelchair. But for Rin's sake, I decided to stay in Nagazora City.
Later, some 500-year-old woman tried to steal my little sister and even tricked me into believing she was my ancestor.
Later still, my sister and I boarded the Hyperion, where our job was to follow a group of girls around and cheer them on.
PS: This story is told in third person. The protagonist has no superpowers and won't be invincible.
