Three years ago, a meteorite hit the Earth and all humans lost their sight. Today, I suddenly regained my sight, only to find that my girlfriend, whom I spent day and night with, had actually turned into a monster long ago. To survive, I continue to pretend to be blind and then go to work at the supermarket as usual. To my surprise, the boss has also regained his sight, so we embark on a journey to fight against the monsters.
