Fear spreads wildly across Tokyo after it is revealed that demons actually exist among us. Paranoia and the darker side of humanity spill onto the streets as people turn on each other, suspecting that anyone could actually be a demon hiding in human clothing. Amidst the growing tensions, tragedy strikes Akira, causing his mind to snap; he retreats into his subconscious, allowing his Devilish alter-ego Amon to break free from Akira's cage of flesh and wreak havoc on both humans and demons alike. Amon: Devilman Mokushiroku is a re-imagining of the last chapters of the original Devilman manga.
