Five “Black Points,” have suddenly appeared on Earth which are gates to other worlds. From these gates, mysterious creatures arise and attack each other, as well as the population of Earth. Coming from five different worlds, these creatures are fighting each other in order to rule over the opposing worlds. Some of the humans can control these creatures with a Card Device and enter the battle. Like in Gate, mysterious creatures enter the human world and attack. The difference is that the action is only in the human world and not in another world. However, there are a lot of action and fighting scenes, which can seem similar to the Self Defense Force in Gate and its military aspect.

The Mirai is a brand new model of ship for the Japanese Self Defense Force and its crew is going to take part in a training out in the Pacific with the US fleet. Caught in a magnetic storm, the navigation system fails for a few minutes and the crew loses contact with the other ships. When the system operates again, they realize that the ship and has been transported into the past during World War II, in the battle of Midway, on June 4, 1942. If Gate is taking place in another world, Zipang is about time travel. In both anime, the characters find themselves in a totally different place and are mostly about military situations. Even if Zipang lacks fantasy, the atmosphere is quite similar to Gate which should be enjoy it!

Elder Tale is a popular MMORPG played by thousands of gamers. While the eleventh expansion pack of the game was released, a system error occurred and 30,000 players are transported into the virtual world. Trapped in the game, Shiroe, the main character, and all the others have no choice than to adapt in this new world. Even if in Log Horizon the characters are stuck in a game, the atmosphere and the genre of the world they're in is similar to Gate. The main character also has similar aspects in both shows, one being a lolicon and the other an otaku. In addition, both anime have a lot of action and strategic aspects.

In a fantasy world, the Devil King Satan is about to conquer the world when he is defeated by Hero Emilia. In order to escape, Satan and one of his generals travel to another world and find themselves in a modern day Tokyo. Compelled to live like the other humans, Satan begins to work part-time, when other characters of his world arrive in the human world. The situation is the opposite of Gate, as the characters of a fantasy world come to the human world. Like in Gate, the characters have to adapt themselves to this new world as their powers are completely useless. With a lot of fun and some action, you will enjoy this show!

Kanou Shinichi is a perfect otaku and a hikikomori. One day, he answers a list of questions on the Internet for a mysterious job and is hired without knowing what the job is about. Then he finds himself in another world, full of fantasy and mysterious creatures. There, Shinichi's job will be to transmit the otaku culture in order to strengthen the links between the humans world and the other world. As in Gate, a brand new world full of fantasy has been discovered and the main character has to consolidate the relationships between the two worlds. Both anime have an otaku main character and even if there is more moe and otaku aspects in Outbreak Company, they are still similar between each other.

Hiraga Saito is a 17 year-old ordinary boy. As he was going to Akihabara, a strange circle of light appears in front of him and he finds himself transported into another world. Summoned and despite his will to be the Familiar of a girl named Louise, he will have to follow her, living in the magical academy she attends. The story is really different, but the concept is pretty much the same, as the main character is conveyed in another world, full of magic and of mythical creatures. Even if the story is not as serious as Gate, this show should be enjoyed by most of us.
