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?!
When poor detective Kuro Daijuuji accepted his first well-paying job, he had no idea what he was getting himself into! The request: to find a magical grimoire for Ruri Hado of the Hado Financial Group. After searching all of the bookstores and antique shops in Arkham City and finding nothing, Kuro is just about to give up when a grimoire happens to fall out of the sky and land on top of him... in the form of a young girl! Her name is Al Azif; and she is being chased by the Black Lodge, a group of evil mages. The two find themselves surrounded, and in order to survive Kuro is forced to enter a contract with Al and become the pilot of the Deus Machina Demonbane.
Demonbane was my second show to review for the 200 club, and I can honestly say it was not impressive. Because of all of its flaws, I would say it is very comparable to Busou Renkin. The animation style is very similar and cartoonish, the action takes a front seat and overshadows any character development and both feature a good dose of fantasy/magic.
The undecided genres of both shows, along with the tentative comedy streak seems to appeal to a lot of people, so I would say if you enjoyed one, give the other a whirl.
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.
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.

Shirahama "weak legs" Kenichi is a typical high school student with typical problems: he's frequently bullied and tends to run away in the face of his enemies. Things change when Kenichi meets Furinji Miu, whose grandfather runs a dojo; and not knowing what he's getting himself into, he signs up to become a disciple. As Kenichi's life-threatening training continues and he becomes more and more powerful, he inadvertently becomes the target of the deadly gang called Ragnarok. With mental and physical challenges ahead, can Kenichi survive his encounters with Ragnarok, or will the masters of his dojo get to him first?
If you liked "Kenichi" or "Busou Renkin", you'd like the other because I think they both hide the same idea. You will notice how in both series the main character meets a girl and with that his life changes completely; then he works hard to become stronger in order to protect others and in the same time tries to understand and eventually 'save' the 'bad guys'. In both series there is a comedy element, but I'd say "Kenichi" depends more on the funny moments :)
