Welcome to a world in which memories can be transferred from body to body; old painful memories can be removed and replaced with new ones, and the poor sell their bodies to the rich to survive. Waking up one day, Kaiba finds himself in a strange place with no memories of his past and a mysterious hole in his chest; the only clue as to his identity is a locket with a picture of a girl hanging from his neck. Armed with this token, Kaiba must now travel across the galaxy to discover who he is and what the girl in the locket means to him; however, his journey will bring him into contact with many people whose lives have been tragically affected by the manipulation of memories. All too soon it becomes clear that something is very wrong with this world…
At the height of civilization, mankind stretched its reach from the distant corners of the globe, to outer space. Man's fate took a turn for the worse when a sudden wind swept across the Earth, causing all human beings to lose every memory they owned, and in essence, their humanity. Now, in a primal world with no rules, one man must endeavor to survive, to discover the future of humankind.
Both are about the manipulation of memories, and what remains when those are taken. They're told in a journy format--the main character learns about the world he lives in through his interactions and revelations with those he encounters on the way.
Life continues as ‘normal' for Birdy and Tsutomu. Though they still co-exist in the same body, Tsutomu is able to focus on his studies while Birdy keeps up with her celebrity job and Federation Investigator duties. However, things become more complicated when a transport ship housing prisoners connected to the Ryunka incident is hijacked. The aliens on board escape to Earth and blend in with the human population, and it's up to Birdy to capture them unharmed and escort them back to headquarters. Yet Birdy soon discovers that there are other forces involved, and it'll take everything she's got to bring these criminals back alive!
There's a really cool dynamic introduced when one character jumps directly into another character's memories. Kaiba jumps into all sorts of peoples memories (for superior breadth on that regard), while in Birdy 2, only the titular character's memories get explored (for superior depth), but both are really interesting.
In 2010, the Britannian Empire enslaved Japan using powerful mecha known as Knightmares; in the aftermath Japan was renamed Area 11, and its people began a hard and terrible existence. Lelouch, a Britannian student living in Area 11, has grown up hating the Empire and everything it stands for. One day, in the middle of a terrorist attack, Lelouch meets a mysterious girl who grants him the ability to control minds. Can he use his new power to fight for freedom, or will his hatred twist his good intentions into mindless acts of vengeance?
Both set in sci-fi world.
Both shows are trying to tell the watcher, that you can have everything and rule the world, but at the same moment you would have nothing.
Both main characters, Popo and Lelouch try to defeat current rulers of the world and take their place. In order to do that, they lose their friends and family.
For centuries, a group of strange children with white hair have been appearing again and again, their origins and purposes unknown; yet always, it would seem, they are searching for something or someone. Now, in the year 2012, they have come to the South Seas to search. There, they encounter the young martial artist Tohma, who has been helping two runaway children from a nearby orphanage, Helga and Chitto. As Tohma learns more about the mysterious children, he also discovers a startling truth about his new friend Helga. A story unfolds that goes back centuries and across the stars, and will change everything in Tohma's and Helga's lives.
Many centuries into the future, humans live as part of the Fractale system, a computer program that moderates their activity to ensure a free and peaceful existence. But while life is indeed comfortable, the cost of growing up in virtual reality communities filled with holographic people called 'doppels' means that it can also get lonely. For Clain living estranged from his parents, adventure finally knocks when he rescues a mysterious girl called Phryne, who appears to be on the run. She spends only a short time with him before hurriedly moving on but leaves behind an unexpected gift: the curious and frustratingly whimsical doppel called Nessa! As Clain learns to adjust to his new friend and survive the scrapes she gets him into, he discovers that she and Phryne are at the heart of a great conspiracy. If he is ever to gain a sense of purpose, Clain will have to leave his comfortable existence and challenge the only thing he has ever known, the Fractale system itself.
Kaiba and Fractale are both dystopic sci-fi animes that throws you into a rich and interesting world that you originally do not understand.
Following both main leads, both animes explores the problems of the futuristic world, delving into deeper and darker issues all the whilst appearing to be an innocent and happy feel.
Kaiba, does however take a more serious tone than Fractale.
The stories and world are eventually explained and explored through the character's interactions, exploring bonds of friendship and love.
Both Kaiba and Fractale also has the element of the main character interacting in the 'real' world as well as with a 'terrorist' organisation looking to overthrow the political institution. Both have characters that appear to be paramount to how the whole system works.
Kaiba remains the more confusing of the series with revalation only coming towards the second half, Fractale being more prefaced from the start.
There is also strong differences in the story telling method. Kaiba explores the effect of the dystopic world in greater details, focusing more on the interactions of Kaiba than dialogue. Fractale deals more with the interaction of the characters, peckered with more light hearted frivolties of the character Nessa and Enri.
