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.
both are sci.fic, comedies and action animes. With plot is mostly about a gigant robot fighting different kind of creatures (or robots).
the only difference would be that demonbane is also magic like.
The eccentric mad scientist Okabe, his childhood friend Mayuri, and the otaku hacker Daru have banded together to form the Future Gadget Research Laboratory, and spend their days in a ramshackle laboratory hanging out and occasionally attempting to invent incredible futuristic gadgets. However, their claymore is a hydrator and their hair dryer flips breakers, and the only invention that’s even remotely interesting is their Phone Microwave, which transforms bananas into oozing green gel. But when an experiment goes awry the gang discovers that the Phone Microwave can also send text messages to the past. And what's more, the words they send can affect the flow of time and have unforeseen, far-reaching consequences - consequences that Okabe may not be able to handle...
In both series, Okabe and Kurou start out as complete losers but their life changes after meeting an extremely intelligent tsundere, whom they grow attached too. As events occur, both guys become obssesed with trying to beat the impossible odds they face and defy fate.
Demonbane is much more action and fantasy based, while Steins;Gate is more suspensful and has plenty of scientific talks. Both series are also based on a visual novel by the same company but while Steins;Gate received an excellent adaption, Demonbane's adaption is rushed. If you enjoyed Demonbane, you should watch S;G and Demonbane can be pretty enjoyable if you set your expectations low.
