- Tonight with the Monsters -
About
On Halloween night, once a year, the worlds of humans and the supernatural collide. In an old mansion on the outskirts of town, a party is held where various monsters—vampires, werewolves, demons, and reapers—gather. Guest, a human, accidentally wanders into this place. Humans are strictly forbidden from entering this mansion. A vampire who makes no effort to hide his identity. A werewolf who can't be honest with himself. A demon who toys with others using sweet words. And a reaper whose thoughts remain a mystery. These four, each with different personalities and races, initially try to drive Guest away, but gradually begin to take an interest in Guest for their own reasons. There is little time left until dawn. Halloween is the only night when humans and monsters can spend time together. Who will Guest choose to spend the night with?
