Amon: Devilman Mokushiroku

Ryou Asuka's revelation that demons can hide among humans sends society into paranoid violence. Mobs begin hunting anyone they suspect, and the terror reaches Akira Fudou's home with a loss so devastating that his fragile hold over the demon fused with him finally breaks.

From Akira's shattered mind emerges Amon, a monstrous warrior whose fury recognizes neither human nor demon as an ally. As Amon tears through everything in his path, Akira is buried deep within their shared consciousness. Regaining his body means confronting the demon from inside, with the memory of the person he failed to protect as his last reason to keep fighting.
