The year is 1969 and alien invaders are trying to dominate the world. The only hope for Earth is AEGIS, a group of teenagers with the special ability to open 'Gates' that let them harness elemental powers gated from another dimension. AEGIS must now seek out other gatekeepers in order to stand a chance against the destruction of the world.
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.
Though much darker and grittier than GK, Scryed has the same element of battling with powers drawn from a mysterious source, fueled by one's conviction, etc.
Some things in life are so bad that you'd like to pretend they're just a dream. Unfortunately for Kazuki, trying to save a strange girl from being brutally killed by monsters (and ending up dying instead) is an unfortunate reality. Out of pity, the girl replaces Kazuki's heart with an alchemy-based artifact known as Kakugane, so that he may live on. With this strange device, Kazuki gains the power of Busou Renkin -- Arms Alchemy; a power that will come in handy when monsters (and worse) begin to plague his town! Kazuki soon meets the girl from his “dream” (named Tokiko) in reality, and she tells Kazuki to get on with his life; but with his sister and friends in danger, that might not be possible. Besides, if Kazuki gives up the chance to show off just how manly he can be, how can he hope to win the heart of the alluring older-sister-like Tokiko?!
Both anime have the same feel to it, allthough Busou Renkin looks a lot better. The "arms alchemy" in BR is a lot like the "gates" they use in Gatekeepers. Check it out, they are both pretty good.
Years after having been exiled from the Kannagi household for being unable to utilize their fire magic, Kazuma returns to Japan, only to discover that the Kannagi family's very existence is threatened. Unknown to them, during his absence, he had become a Contractor and thus acquired a vast strength in wind magic. Not showing any remaining contempt for them, he offers to help solve the Kannagi household’s problems in return for large sums of money. Together with his younger brother Ren and the feisty heir to the Kannagi household, Ayano, he fights to protect those he cares about... for a price!
Both protagonists are able to control the power of the wind along with their companions who can summon the abilities of other elements. Their lack of motivation joined with a dislike for their fathers help fuel the story. Some slight romance with the tsundere character and plenty of comedy packed in between the action keep these two choices high up on my list of favorites. Both are an excellent watch!
At the end of the 20th century a fierce war raged between the Monsters and the humans. The outcome was devastating for humanity -- as the Monsters had won -- and thus a new era of Monster-ruling began. These Monsters feed on children and can turn any human who sees them into either a puppet or stone -- except for the Melos Warriors who are the only ones able to fight them. Meet Bokka, a young aspiring Melos Warrior whose only goal is quite simple: to save the Melody of Oblivion and vanquish the Monster King, once and for all!
These two shows are extremely similar in so many ways, with plenty of fast paced action and high school kids teaming up to defeat the enemy with super powered weapons.
MoO and Gatekeepers both have quite a dark undertone, but balance that with comedy and ecchi. *Warning* The ecchi in MoO does get very overbearing, especially at the end when story is sacrificed for a nice pair of boobs.
Gatekeepers focusses more on friendship and teamwork, whilst MoO is about each individuals struggle with their warrior name and true love. However, if you enjoy a fast paced, slightly eccentric show, you should give them both a try.
Guided by a star only they can see, a group of maidens known as HiMEs have begun to gather at Fuuka Academy. These young women have been endowed with dangerous supernatural powers that they can use to their heart's content, but there's a price: to wield them, they must put their most important thing on the line. Now, in the midst of school work and friendships, they find themselves caught in the midst of strange conspiracies seemingly related to the terrifying monsters that attack them. Is the power of the HiMEs strong enough to save themselves and the ones they love?
Gatekeepers and My-Hime feature kids that discover they have extraordinary abilities, and must then protect their worlds. While the characters in Gatekeepers fight against an alien race, the ladies in My-Hime fight against the influence of a long forgotten king, and each other, in order to protect the ones they love. Both anime have amazing fight scenes and blossoming romances.
