Synopsis
Ayakashi, a former member of the 6th Division of the Investigation-Yamaki made a decision. An "existence" that can attack and kill allies, and use all possible means to eliminate it from the world and protect it. On the other hand, the "existence" that Yamaki is aiming for-Taichiro Yamazaki was confused. This is because the parasitism of the demon slasher has progressed, and the continuity of consciousness has been cut off each time Ayakashi approaches. Despite Yamazaki's desperate wishes, the transformation of consciousness progressed further, and ...! The first demon slash that sucks Ayakashi's life and robs the human soul-a child slash. Now, the battle begins over the "Doji Sword".
