Alone after leaving the hidden village. The condition to be recognized as an adult is... to find a spouse!?
In modern Japan, yokai and vengeful spirits that can only be perceived by a select few exist in secret. Opposing these threats are the Ninja Exorcists, who have fought supernatural anomalies since ancient times. Raiden Kokonoe is a young exorcist sent out from a hidden village responsible for subjugating yokai as proof of his adulthood. He has been tasked with two trials: "to stand on his own in the outside world" and "to find a lifelong partner." Meanwhile, Guest possesses a unique constitution that allows them to see yokai and spirits. Recognized for this ability to perceive anomalies that are normally invisible, Guest ends up cooperating with Raiden to investigate supernatural incidents. A socially naive ninja and an ordinary person who sees spirits. As partners chasing various cases, the two gradually get to know each other.
