Time has passed since Akira Fudo was possessed by the powerful demon Amon, giving him the ability to change into Devilman. Humans have become increasingly paranoid of demon attacks, resorting to murder of innocent civilians with mob mentality – among nicer things. Akira continues to fight against the demon armies with his companions – but when his girlfriend Miki is brutally murdered, his will breaks and the sadistic Amon is unleashed, controlling his body. The final battle awaits in Akira’s mind – can he defeat Amon and control his body once more?
Much to the annoyance of Kei, he and his childhood friend Katou have died, having been torn apart by a train. But rather than finding themselves at the gates of heaven, the duo materialize in a room full of strangers and a giant black sphere known as GANTZ. As if dying once wasn’t bad enough, the occupants of the room are then forced to embark on dangerous missions to kill strange aliens; missions that very few return from. Now, Kei, Katou, and a well-endowed friend must fight for their freedom with an arsenal of guns, high powered suits, and a very low chance of survival.
Though Gantz and Amon are not even remotely similar as far as plot, both have two things important in common: violence and gore. While it's true that there are a plentiful amount of anime series that have excessive violence, few take it to the level that Gantz and Amon do. No one is safe, the attacks are exceptionally brutal, and the envelope is definitely pushed on a regular basis. If you liked the violence in one, try out the other.
Hajime Shiroishi is a disturbed, troubled boy. He is bullied endlessly by his classmates, betrayed by those he calls friends, and privy to the bizarre sexual exploits of his parents; and to top it all off, he can’t cope with the fact that the idea of violence excites him thoroughly. As each day passes, Hajime finds himself slipping more and more into madness and the rage within him builds. It is only a matter of time before he snaps and becomes who he was meant to be: the ruthless and deranged Ichi the Killer...
While Amon and Ichi the Killer have entirely different stories, they share one important thing in common: each inundates the viewer with violence and torture for the sake of violence and torture. While I'd never watch either again, they certainly excel at what they aim to do. Fans of one should check out the other.
Shinichi Kuruma is an experiment gone awry. With the ability to summon a lion and bear from his body and superhuman strength, he is one of many 'New Humans' created by Shinichi's own father, Genzou Kuruma, who wants to control the fate of those who will inherit the Earth. Alongside a girl named Ayaka who was injected with Shinichi's special blood, Shinichi must stay out of the reach of the other New Humans and scientists who wish to use his lifeforce to revive God; but most importantly, he must find a way to exact his revenge on his father.
It's exceptionally rare for me to see something so violent and gory that I'd have a recommendation for Amon; now is one of those times. Demon Beast Phalanx TV and Amon are chock full of disturbingly graphic gore (children aren't safe in either), and frankly BOTH could have come from the mind of Go Nagai given the endless ridiculous beast creatures (only Amon is from Nagai).
Trust me, this is an ideal recommendation.
