The power to cross over dimensions is one that is deeply coveted -- a lesson that childhood friends Sakura and Syaoran learn the hard way when an unknown enemy attacks an archaeological dig in their country. As a result, Sakura's memories are scattered to different dimensions, causing her to fall into a deep sleep. In order to save Sakura's life, she and Syaoran must journey to various worlds in search of her memories, with the help of fellow travelers, Fai and Kurogane. But finding Sakura's memories won't be easy, and the price for traveling through time and space is high...
The first law of alchemy is that "one cannot gain something without giving something of equal value in return" - a rule that two souls dare to cross. When Edward and Alphonse Elric try to revive their dead mother, breaking the taboo of human transmutation in process, Ed loses his right arm and left leg while Al loses his entire body. After the tragedy, an alchemist named Roy Mustang visits them and tells Edward to become a state alchemist to find a way to recover what they have lost. Accompanied by Al, whose soul is now attached to a metal suit of armor, Ed is fitted with auto-mail parts in place of his lost limbs and becomes a state alchemist by the name of "Full Metal Alchemist." Together, they set forth on a journey to find the Philosopher's Stone - the one item that is rumored to have the power to restore them.
Fullmetal Alchemist and Tsubasa: Reservoir Chronicle are both shounen works with truly amazing plotlines. They are full to the brim with shocking plot twists and suspense. They also seamlessly blend in superb action sequences without sacrificing the plot, as some other shounen works tend to do. If you enjoyed the plot of one, you will probably like the other.
The heroes of these stories fight with everything that they have to restore someone that they love back to their original state. Danger isn't always straightforward, and there's no way Edward or Syaoran to know how close he is to success, but neither of them shows any signs of stopping.
These shonen series are similar for their epic storylines and themes. The ideas of equivalent exchange to grant a wish and the impossibility of resurrecting the dead even with enormous sacrifices are explored.
Ed and Al in Fullmetal Alchemist go on a journey from town to town as they search for a way to regain their previous bodies. In Tsubasa, Syaoran and his band of travelers traverse dimensions to recover the missing feathers/memories of Princess Sakura.
While Fullmetal Alchemist has heartwarming moments and comic relief punctuating the darkness of the series, Tsubasa takes a different approach. Tsubasa: Reservoir Chronicles hints at an overaching conspiracy and major villain throughout the lighthearted first half. Starting in volume 15/16's Tokyo Revelations arc, the second half of the series becomes wildly different in tone from before, having more violence, tragedy, and plot twists.
Hikaru, Umi, and Fuu are Tokyo schoolgirls with nothing else in common, until one fateful day at Tokyo Tower changes everything: the three are transported to the magical realm of Cephiro, and find that their fates are inexorably intertwined. The sinister Zagato has kidnapped Princess Emeraude, whose will power keeps Cephiro safe, and the three girls are told that they must become the legendary Magic Knights in order to save her. This task will be difficult and dangerous, as Zagato has sent his most powerful minions to stop the girls before they can fulfill their destinies. Protected by an ancient wizard's blessing and determined to find their way home, Hikaru, Umi, and Fuu set out on the adventure of a lifetime
Both stories feature people traveling through various universes and using magic to fight evil. Also, both have a "damsel in distress" in some form.
1. They both include searching for something
2. They both have someone going between worlds.
3. Syaoran, Sakura (TRC), Umi, Fuu, and Hikaru (MKR) are all about fourteen years old.
Both series were drawn by CLAMP, so the art and storytelling are quite similar. Beyond that, these two are classic hero stories, where people have to fix problems in a world that is not their own in order to save everyone.
Five hundred years ago there lived a feudal lord with a vast amount of spiritual power. To keep it from falling into the hands of demonic Ayakashi, the mage Tokimori Hazama and his two students were called to defend the land. However, they fell ill, and the feudal lord was killed and buried on the land now called Karasumori. Years later the successors of the Hazama students, Yoshimori and Tokine, have inherited the powers of the Hazama clan. They are Kekkaishi, users of the Kekkai, a secret and powerful technique that creates a strong barrier to capture and eliminate Ayakashi. Protectors of the power buried beneath Karasumori, Yoshimori and Tokine spend their days in the school built on the land, and their nights defending it from attackers who wish to use the power for their own purposes. With Karasumori's power growing more unpredictable everyday, will Yoshimori become strong enough to protect the ones he loves?
In both of these manga, a boy develops a crush on a girl with a higher status than him. Their idyllic worlds are shattered, and very quickly, the boy grows into a powerful defender who will do anything to protect the girl he likes. You've got to admire that dedication. :)
Following its destruction many years ago, the world now consists of many disconnected lands that once again face the threat of annihilation. Sora is a young boy who lives on a tropical island with his friends Riku and Kairi. However the night before the trio is due to set sail on an exploration voyage, they encounter monsters known as the Heartless. During his struggle with them, a large Keyblade appears before Sora and he is transported to the faraway Traverse City. There he meets Donald and Goofy, two representatives of the king who are in need of his power as keybearer. Now, Sora travels with his new companions in order to find the keyhole hidden in each world and lock away its heart to protect it from harm, hopefully finding out what happened to his friends along the way. But with other evil forces afoot, will Sora and the others really be able to save everyone and keep all worlds safe?
Both series' has characters who travel to many different and interesting worlds. With a slightly light-hearted tone, both series also seem to have a feeling of eminent sadness as well. Both really good to read, particularly if you enjoy crossovers as both are full of them.
Haru Glory lives peacefully on Garage Island with his sister. One day, Haru fishes a strange dog-like creature named Plue out of the ocean, and soon after meets its master, an old man named Shiba. With this man comes terrible news: the world is in peril, for the evil organization Demon Card is attempting to conquer it with power-giving stones known as Dark Bring. To combat this threat Shiba has spent much of his life fighting back with Rave, a Holy Bring; and the Ten Commandments, a sword it powers. When members of Demon Card arrive at the island, Shiba discovers that Rave and the Ten Commandments will now only respond to Haru, making the young boy the new Rave Master. Armed with newfound power, Haru and Plue set forth to put a stop to Demon Card.
While the general moods of these manga are different, both Rave Master and Tsubasa: Reservoir Chronicle are stories about a boy who risks everything for an important girl. Elie and Haru take some time to build this dynamic while Sakura and Syaoran already have it at the start, but it's not uncommon to see one of the guys taking a huge risk for the girls. It's kind of heartwarming. ^_^
