It has been 800 years since the incredibly fast and powerful gods of battle known as the Idaten had sealed away the demons after an intense battle. Now, that battle is just considered a myth or a fairytale. While the current generation of Idaten who have never even had to fight are enjoying their peaceful lives, someone awakened the demons once again! Armed forces, ingenuity, politics, and intrigue. If you've got it, use everything you can! This three-way battle royale with no rules and no limits is about to begin!!

The Medicine Seller is a deadly and mysterious master of the occult who travels across feudal Japan in search of malevolent spirits called mononoke to slay. When he locates one of these spirits, he cannot simply kill it; he must first learn its Form, its Truth, and its Reason in order to wield the mighty Exorcism Sword and fight against it. He must begin his strange exorcisms with intense psychological analysis and careful investigative work—an extremely dangerous step, as he must first confront and learn about the mononoke before he even has the means to defeat it.

Turns out, evil takes initiative! With world domination close at hand, the Kisaragi Corporation turns its sights on interstellar conquest, and who better to take over a magical world than two randomly assigned minions—Combatant Agent Six and his android partner Alice?

However, Mio's life is in danger as she is pursued by demons and heroes!

Akira Oda and his high school classmates are summoned to another world! While the other students are granted cheat abilities through the summoning, Akira merely gains the abilities of a mediocre "assassin."

The Great Jahy, the Dark Realm's second-in-command, cuts a frightening figure, feared and revered by all. But when a run-in with a magical girl results in the destruction of the precious mana crystal, the Dark Realm falls, transporting the newly tiny and powerless Jahy to the human world! Unfortunately, plotting the revival of the Dark Realm from a cramped, crumbling one-room apartment is no easy feat when you have rent to pay and a job to keep!

When a shapeshifting demon with a thirst for human flesh, known as "youma," arrives in Raki's village, a lone woman with silver eyes walks into town with only a sword upon her back. She is a "Claymore," a being manufactured as half-human and half-youma, for the express purpose of exterminating these monsters. After Raki's family is killed, the Claymore saves his life, but he is subsequently banished from his home. With nowhere else to go, Raki finds the Claymore, known as Clare, and decides to follow her on her journeys. As the pair travel from town to town, defeating youma along the way, more about Clare's organization and her fellow warriors comes to light. With every town cleansed and every demon destroyed, they come closer to the youma on which Clare has sought vengeance ever since she chose to become a Claymore.
