Subaru Sumeragi is the 13th head of the Sumeragi Clan and a most powerful onmyouji. Subaru is hired to exorcise a construction site, but his employer mysteriously died. The only suspect is a man who repeatedly walks away from situations in which he should have died. Then Subaru meets a young woman intent upon cursing the man, saying that he killed her brother. Subaru must figure out how his employer died and fight the evil spirits that are protecting the man with the help of his friend and twin sister, Seishirou Sakurazuka and Hokuto Sumeragi.

According to Kadokawa, an OVA of R-15 will be bundled with the tenth volume of the novel.

Tadashi Matsushita has recently entered the Kansai Fifth Technical High School and joined its notorious karate club. There he meets his captain, Yoshiyuki Takagi, an incredibly strong individual. Feared and respected throughout Osaka, Takagi is deep down an honorable and compassionate guy despite his violent endeavors.

Tatsuko of class 5-1 is really excited about the upcoming school sports festival, her proposal for a new "Eel Scooping" event is less than enthusiastically received though, especially by Suzuka. Illya mentions the main event dance to Miyu, and as teacher Taiga Fujimura points out, it entails a huge reward, but will require quite a bit of practice. And so the close friends: sarcastic Nanaki, level-headed Suzuka, excitable Tatsuko, energetic Illya, shy Mimi, and reserved but athletic Miyu are off to win the dance event for the honour of their class and for Fujimura, who seems to have some saucy bet going on that she most definitely needs to win, or so the girls misunderstand.
