Fifty years ago, the Demon Stone and RAVE (two powerful artifacts) are broken and scattered throughout the world. The story follows the journey of Haru Glory; during his travels he meets many new friends and allies, and also enemies known as the Daemon Card. He will have to use the powers given to him by RAVE to defeat the Daemon Card and find the other pieces of RAVE.
Some years into the future, a strange, unexplainable natural disaster has broken off a piece of the Japanese mainland. Known as the Lost Ground, it is now inhabited by people with Alters -- machine-like extensions of their own will. In order to keep the peace on the Lost Ground, the HOLY organization uses its own Alter capabilists to police the region. In the midst of the chaos is a young man named Kazuma, whose life will soon change forever as he discovers his hidden abilities, and how to wield them.
In a bizarre fantasy world, students known as meisters are trained at the illustrious Shinigami Weapon Meister University; but the tools they wield are no ordinary weapons! Each meister is paired with a human-like being who can transform into a weapon at will; and after defeating a pre-kishin - a human whose soul has darkened - the weapon eats the soul within it. A meister's ultimate goal is to collect ninety-nine pre-kishin souls and one of a witch so that his or her partner will become an all-powerful Death Scythe. Maka and her partner Soul Eater; Assassin Black Star and his partner Demon Blade Tsubaki; and Shinigami's son Death the Kid and his partners the Demon Twin Pistol Thompson Sisters each vie for their ultimate goal, but plenty of challenges and adventures lie in their way!
Rave and Soul Eater are very shounen, very action-filled romps that appear to have come straight out of a video game. The mood and feel are very similar and overall I think this is a good match.
Many similarities in how the characters feel, its hard to explain.... they just both carry strong messages!
In the present, mankind lives in an era named the Dark Century, a time filled with fear due to the actions of the Vandels. These domineering tormentors rule with an iron fist, bringing death and despair to mankind. But in the midst of the terror, there is one thing the Vandels fear: the Vandel Busters. Enter Beet, a young boy whose only dream is to grow up to be the greatest Buster of them all. Join our hero as he journeys to join the Zenon Warriors and destroy the Vandels. With the help of friends and a little luck, Beet might be able to put a stop to the Dark Century, once and for all!
Even though neither Rave nor Beet floats my boat, I feel it's safe to recommend these two anime for each other. In an adventurous world, one is seeking out power to destroy \ evil-doers. Adding a bit and humor with the fights, the atmosphere is very alike. I guess what differentiates them from the typical adventure anime is that they don't develop a deep story and are aimed more towards younger teens.
In the present, Japan is under assault by murderous creatures known as Aragami whose origin and purpose remain unknown. The fate of Japan and the world itself lies with one young woman named Momiji who bears the burden of the Kushinada -- the one who must be sacrificed to silence the Aragami forever. With the help of Mamoru Kusanagi (a human and Aragami hybrid), and an agency filled with firepower-toting bodyguards, Momiji must use her Aragami-sensing powers to help save mankind; but will she ultimately have to lose her own life to save the lives of so many others?
Groove Adventures Rave has a similar story to Blue Seed, with a "save the world from evil and destruction" type of feel. Only, in Groove a sword is used instead of hand-to-hand 'seed' combat.
It is the year 300X, and the Earth is in peril! Tsuru Tsururiina, the evil dictator of the Margarita Empire has sent his elite troops to Earth to snatch every last hair on the heads of the unsuspecting populace! But there is one man who will stand up against the malicious invasion and save everyone from the terrible horror of baldness: Boboboubo Boubobo! Using his secret art of nose hair combat, Boubobo will not rest until the Margarita forces are gone from Earth for good. But can he succeed without the help of the pink-haired girl Beauty, or the mysterious Pickle that follows him around?
