(Cthulhu + City + Urban Power + Group Image + Academy) In the shadow of the modern city, five college students accidentally came into contact with an ancient book connecting to the otherworld of Cthulhu. They discovered that the so-called "real world" was just a fragile appearance, and the real terror had already penetrated into every corner of the city. Facing the gradually awakening Old Ones and the secret organizations trying to harness the power of otherworldly forces, they must find a way to survive between reason and madness.
