Seikyou Private Academy, built on the intrigue of traditional occult myths, bears a dark past—for 60 years, it has been haunted by a ghost known as Yuuko, a young woman who mysteriously died in the basement of the old school building. With no memory of her life or death, Yuuko discreetly finds and heads the Paranormal Investigations Club in search of answers. A chance meeting leads Yuuko to cling to diligent freshman Teiichi Niiya, who can see the quirky ghost. They quickly grow close, and he decides to help her. Along with Kirie Kanoe, Yuuko's relative, and the oblivious second year Momoe Okonogi, they delve deep into the infamous Seven Mysteries of the storied school.

After working himself to death in a hostile corporate environment, Yuuji Sano gets a second chance when he transmigrates to a game-like fantasy world. Although he wishes to lead an unassuming life, Yuuji learns that he has the title of a Monster Tamer, the weakest rank of adventurer. With his newfound skills, he tames a number of slimes around him and, with their help, acquires magical powers to become a Sage—a second profession that capitalizes on such potential. Even after gaining overwhelming strength, the scars from the life Yuuji left behind keep him from going all out. However, he might not be able to hide his abilities for much longer, as unforeseen dangers threaten to destroy the world that is now his only home.

Since ancient times, shrine maidens who wield swords have been exorcising aratama, strange existences that threaten the human world. These young women who wear school uniforms and a sword are called Toji, and they serve as an official unit within the police force as a special religious service police squad. The government authorizes the Toji to wear swords and serve as government officials, and the government has set up five schools throughout the country for the girls to attend. In the spring, the five schools send their best Toji to compete in a tournament. As the tournament comes closer, all of the representatives rigorously train themselves in order to get stronger and improve their skills. (Source: ANN)
