Plot
Set in an alternate timeline, during the Belle Époque era in the late 19th century, where supernatural creatures such as vampires and oni exist in the same world as humans. Tsugaru Shinuchi, an experimental half-oni known as the Oni Slayer, accepts a job from an immortal woman named Aya Rindo with her loyal servant Shizuku Hasei. Tsugaru wishes to find a way to extend his lifespan, while Aya exists solely as a talking head who wants to die. When they both realize the person behind their current predicament was a wealthy foreigner with an "M" printed on his cane, they leave Japan for Europe and try to track him down. While trying to locate Aya's missing body and hopefully their target with it, the trio take on supernatural mysteries across Europe with Tsugaru taking on the persona of "The Cage User" for the birdcage he carries with Aya's head inside.

The Cage User

 * Aya Rindo (輪堂 鴉夜)
 * A young Heian era woman and a yōkai, who is beheaded by an unknown half-oni assailant from Britain and has her headless body taken away. Since she is a Fushi (a kind of immortal youkai), she cannot die (though being decapitated by a half-oni means she cannot heal herself) and thus her head continues to live on, ultimately seeking support from Tsugaru to get her body back and take revenge on the man who left her like this.

 * Tsugaru Shinuchi (真打 津軽)
 * A former member of a special oni extermination squad charged with slaughtering monsters across Japan during the Meiji Restoration. At some point, he was injected with oni blood by the same man who beheaded Aya and turned into a half-oni himself. Though the power allows him to kill oni and other supernatural beings with his bare hands, he knows that at some point in the future the oni blood will overcome his human personality and he will be put down by a similar hunter. In the meantime, he supports himself by fighting other demons in cage matches as a circus act called the Oni Slayer.
