College student Sorawo Kamikoshi explores "doors" which lead into the Otherside— a parallel world in which urban legends and internet creepypasta are brought to life. When Sorawo nearly dies, she's rescued by Toriko Nishina, another young woman who is looking for a lost friend. With the help of a woman named Kozakura, they return to the Otherside, but the two are increasingly affected by the conditions of the world, and find themselves increasingly affected by each other.
