S01E01 The Witch's Son
Kazuki Azuma returns to Japan after ten years away, only to be chased down by the Bubuki police. He's saved by a childhood friend, Asabuki Kogane, and her right-hand-shaped Bubuki. He then meets the Bubuki...
The Buranki Entei flies freely through the sky... and the one controlling it is not Reoko, but Kaoruko. Demokratia, led by Guy, has used its technology to make Entei recognize Kaoruko as Reoko. Guy then tells Kaoruko that there is a traitor among them in Demokratia, but she's unable to conceal her shock when told that the traitor is a fellow Bubuki user and ordered to eliminate them.
It’s been ten years since Azuma Kazuki has been in Japan, and upon his arrival he is taken prisoner by a group of armed men. Azuma is saved by his childhood friend, Kogane Asabuki, thanks to a living weapon she wields on her right hand, known as a Bubuki. Learning about these weapons, Azuma becomes a Bubuki wielder himself and sets out on a journey.
