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.
One stormy night, a desperate man finds himself playing Mahjong with yakuza thugs; the prize is his life. He is losing, and death seems certain, until a teenage boy stumbles out of the darkness into the Mahjong parlor, drenched in rain. Allowed to watch, the boy soon offers to play in place of the marked man, and that night, a legend is born. After his first taste for Mahjong, Akagi Shigeru finds himself entangled in the dark underworld of Mahjong gambling: for money, reputation, and lives.
While about vastly different subject matters, both GANTZ and Akagi have a strong themes of violence, extremely high stake games and a dark environment. The tone of the two shows is similar, but GANTZ is substantially more violent, graphic and possibly disturbing for some.
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?
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.
Death and reincarnation are inescapable, but what happens in between? Without warning and without his memories, a boy who only recalls his last name - Otonashi - wakes up next to a girl named Yuri who offers him a gun and tells him to shoot an angel. Assuming it must be a misunderstanding, Otonashi is then almost killed by the angel and is drawn into Yuri's army to battle to delay the beginning of his next life. Immortality is within reach, but if Otonashi remembers how he died, will he keep fighting or allow himself to vanish?
Gantz and Angel beats has a similar atmosphere while both of them posses fighting on the afterlife. GANTZ is more brutal and garners on the adult audience more it is more focused on action and character development while on Angel beats its more on the steady side of the story with more comedy and added romance but non the less if you enjoyed GANTZ you might enjoy Angel beats which has a similar atmosphere but a different kind of twist.
Witness the true beginning of the Matrix: how men created the machines and how those machines stood up against their masters, and the effects of the great war that waged between them, which in the end led to the fall of mankind. Watch the ship Osiris and its efforts to warn the remaining humans of the imminent attack; follow a champion who happens to break free from the Matrix; explore the exploitation of a glitch in the overall system; observe the story of the Kid and how he was found by Neo; travel with an investigator who tracks the well-known hacker Trinity; and learn the secrets of the Matrix in other wondrous ways.
Both GANTZ and Animatrix feature a life beyond life, be it in the Matrix or The Game. Also they each deal with the effects this has on normal people ( Kei from GANTZ may be annoying, but people like him do exist in life).
It's the 1930s, and Mafia groups fight for supremacy in American cities. Young Firo joins the secretive Camorra group; a meek street boy, Jacuzzi, finds himself the leader of a gang of thugs; an alchemist is producing a liquor of immortality, and a homunculus tries to retrieve it; and upbeat thieves Isaac and Miria head to New York after failing to strike gold in California. They ride the novel train, the Flying Pussyfoot, across the continent. However they find themselves embroiled in a ruckus caused by gangs, terrorists, serial killers, and others as multiple stories intertwine and unfold on this fateful ride. All are haunted and hunted by the legendary Rail Tracer...
Violance, brutality, gore and blood. That's quite a good characteristic for these anime. Although Baccano has some kind of comedy relief (quite hilarious if you ask me). Both shows mix good animation with bad taste action scenes, noone is safe even children. Still If you want to wake up after some lighthearted romance/comedy you couldn't possibly pick better.
