When Hiro Hiyorimi tries to save a beautiful young woman from certain death, he ends up a dead hero himself! However, since the drop-dead girl is Hime, daughter of the King of the Monsters, his reward is to come back as a not-quite-living soldier in her honor guard of horror! That means helping fight off the army of supernatural monstrosities Hime's siblings are unleashing against her in hopes of moving up the ladder of succession. And if facing off with vampires and zombies isn't bad enough, how can anyone be prepared for the REALLY weird ones, like were-sharks, pandas and killer dumplings? This sure as hell isn't the afterlife Hiro was hoping for, but the really sad part is that Hime is the good girl in all of this... or at least as close to good as you can come when you're on the wrong side of the gates of hell!

Koyomi Araragi spent his last year of high school helping girls in his town resolve various supernatural afflictions. But now Araragi has departed for university, leaving his friends to fend for themselves against new problems and curses that plague them. Yotsugi Ononoki, once a human corpse and now a living doll, takes residence in Araragi's home, keeping watch over his sister Tsukihi, a girl harboring a mystical secret of her own. As part of her duties, Yotsugi fills Araragi's vacated role as occult expert, assisting others in town with their issues. One of these girls, middle school student Nadeko Sengoku, slowly recovers from her own recent brushes with the paranormal. She avoids returning to school, instead spending time alone in her room and pursuing her dream of becoming a professional manga artist. In order to speed up Nadeko's quest for mastery of her craft, Yotsugi convinces her to create four copies of herself, each representing a distinct aspect of Nadeko's personality. However, the clones refuse to help Nadeko, instead escaping into the town and creating a chaotic mess. Now forced to grapple with her own fractured sense of identity, Nadeko sets out to capture them and resolve her inner conflict.

Within Cardia Beckford's hazy memories, she can recall her father Isaac and the home where she lives alone, feared as a monster by the townsfolk—for in her body, she carries a deadly substance. Embedded in her chest by her father, the eternally beating heart—also known as Horologium—has the capability to produce infinite power. However, it also makes her skin destroy anything it touches. Many in London seek the Horologium, including the terrorist organization Twilight, with whom Isaac is rumored to have close ties. To obtain the Horologium's power, the British military forces Cardia to leave her home as their prisoner. But on the road, she is whisked away by the gentleman thief Arsène Lupin, who says he will steal her heart. Joining Lupin and his companions, Cardia begins a journey to discover the truth behind Isaac's connection with Twilight, her missing memories, and the Horologium within her chest.
