The Walpurgis Royal Academy of Machinart was founded alongside the development of "Machinart," machine magic capable of giving life and intelligence to mechanical dolls subsequently called as "automaton." Its aim: train skilled puppeteers to control the automatons, as militaries across the globe have begun incorporating Machinart into their armies. After miserably failing the academy's entrance exams, Raishin Akabane and his humanoid automaton Yaya must defeat one of the top one hundred students to earn the right to take part in the Evening Party, a fight for supremacy between puppeteers using their automatons. The last one standing is bestowed the title of "Wiseman" and granted access to the powerful forbidden arts. Thus, Raishin challenges Charlotte Belew and her automaton Sigmund to a duel, but before they even begin, Sigmund is attacked by other students. After saving his opponents from their assaulters, Raishin cancels the duel but is forced to search for a new way to gain access to the Party. Driven by the tragedies of his past, Raishin fights alongside Yaya to rise to the top and claim the title of Wiseman. [Written by MAL Rewrite]

Three kids are stuck in a strange city causing massive mayhem through the land. They are searching for an atypical rabbit in order to return home. Koto, the eldest of the three, seems to have some sort of connection to this weird place ruled by a monk, a demon, and a priest.

High school student Ibuki Keita has been haunted by misfortune for as long as he can remember. For no apparent reason, everyone around him dies tragically. Ultimately, he refuses to become too close to anyone, even his childhood friend Akane. This leaves Keita alone in a life full of misery and disgrace. While eating at his favorite ramen shop one evening, Keita meets a strange young girl named Kuro. Possessing abilities that surpass that of a normal human being, Kuro classifies herself as a Mototsumitama. She explains to Keita about "Terra," a life-energy force split between three identical looking people; a global phenomenon dubbed the "Doppeliner System." As a Mototsumitama, Kuro guards the "Coexistence Equilibrium," the beings that protect the flow of Terra around the world. Keita refuses to believe her story, until he is caught up in the crossfire of this hidden world. On the verge of death, he makes a contract with Kuro, unbeknownst to its true meaning. Now he is bound to Kuro, and must be with her at all times. Could Keita's misfortune possibly get any greater?

Vampires—supernatural beings that feed on the life essence of the unsuspecting at night—have been around for centuries. However, high schooler Karin Maaka is unusual, even among her own kind. Unlike her vampire family, ever since she was a child, Karin has suffered from polycythemia: a rare disorder which causes her to periodically produce excessive amounts of blood. And the more blood she produces, the more anemic and lightheaded she gets, ultimately leading to frequent nosebleeds. Her only solution? Force her excess blood onto random strangers, which surprisingly causes these "victims" to become livelier and happier than before. With her siblings—Anju, her reserved yet affectionate younger sister, and Ren, her womanizing elder brother—helping her abilities remain a secret by altering the affected humans' memories, no one is the wiser. That is, until Karin's newly transferred classmate, Kenta Usui, finds her behavior suspicious. And to make matters even more complicated, Karin feels her blood reacting unusually to Kenta's presence.
