In Gintoki's Japan, the arrival of the various space races known collectively as the Amanto ended the era of the samurai. The Amanto's highly advanced technology resulted in total conquest and a severe economic shift. Now, former samurai such as Gintoki scrape together whatever livelihood they can. Gintoki's profession of choice is that of a yorozuya: he'll complete any job for money. However, he’s unmotivated; and spending most of the day on the couch with the latest issue of Jump and a carton of Strawberry Milk is his preferred pastime. It turns out that his new unpaid employees, Shinpachi and Kagura, are going to interfere with his pastime even more than with his "work"! Of course, none of this means he has really given up on his samurai ideologies!
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.
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.
In today's technology-driven society, everything has to move with the times, and magic is no exception. As spells are cast with various magic "codes", made up of binary digits, a computer becomes just as useful to the aspiring mage as a magic wand. One such would-be wizard is Koyomi Morishita, a girl who suffers from a bizarre inability to cast more than one type of spell. No matter how hard she concentrates she can only use code to do one thing: summon metal wash basins, directly above people's heads more often than not! Hoping to improve her versatility, she becomes a student of voluptuous expert witch Misa Anehara. However, with malevolent "daemons" - monsters summoned by unscrupulous magic wielders - appearing at every turn, Koyomi will need all the help she can get!
This is a bit of an odd pair, but my excuse for recommending them is that both YWGM and Steins;Gateboth feature a lot of technology and gadgets, such as cellphones and computers. Yoku Wakaru has way more magical girl action, but if you like your codes, you might give it a shot too.
The normally sleepy town of Inaba has recently fallen prey to a string of bizarre deaths, where the deceased are discovered dangling from TV antennae and telephone poles. But that’s not the only mystery that’s cropped up lately: the "Midnight Channel" has gained notoriety in the local high school for allegedly revealing a person's soul-mate to them. When transfer student Yu arrives in town, he quickly becomes enmeshed in the center of all these mysterious goings-on, especially after the teen and his friends are pulled through the television into another world! How is this strange place connected with the other mysteries plaguing Inaba?
Although the games that both shows are based on aren't too similar, both Steins;Gate and Persona 4 are excellent examples of video game adaptations done right. Neither feel too bogged down in a video game style pacing, but don't jettison everything and start from scratch either.
Plotwise, both revolve around high school age students engaged in a mystery with science fiction/fantasy elements, and have a likable cast of characters. Both shows also manage to balance light-hearted elements with the darker mystery, and strike a very similar tone.
A man is miserable. Despite all his dreams of a “Rose-Colored Campus Life” filled with raven-haired maidens who dote on him, his social life is going nowhere. He has no girlfriend, his only good friend keeps getting him into trouble, and the circle he joined brings him no joy. So he tries again, and again, reliving his first two years of college life ad nauseum, making different decisions each time, having no recollection that he’s already done this all before. Will the man ever be satisfied with how his life turns out?
Both deal with alternate realities and "would have, could haves," yet the protagonist seemingly keeps coming up with the same result albeit through very different pathways.
If you enjoyed the exposition of the possiblilities in one you will like the other.
