Gate

The military fantasy series begins when a gate appears in Tokyo's Ginza district sometime in the 21st century. From the gate pours out monsters, knights from middle-age Europe, and other fantasy-like beings, and they kill many of the citizens of Tokyo. This event is known as the Ginza Incident. The government sends a small group of soldiers from the Japanese Self-Defense Forces (a replacement for Japan's military) to the alternate world beyond the gate. Led by otaku soldier Youji, they find that the villages in the world are being attacked by a dragon. An elf girl who is a survivor from the dragon's rampage joins the group in their travels across the dangerous new world. (Source: Anime News Network)

The Devil is a Part-Timer!

Devil King Sadao is only one step away from conquering the world when he is beaten by Hero Emilia and forced to drift to the other world: modern-day Tokyo.

KONOSUBA -God's blessing on this wonderful world!

Kazuma Satou decides that today is the day to get out of the house for a bit. Since he dies, pointlessly, it's clearly a bad choice. The goddess who greets him in the afterlife, however, offers him a chance to be reborn in a world not unlike that of a video game, and as a bonus she'll even throw in a cool item or power! Can't possibly be a bad choice, right? Except he arrives with no money at all, dead average skills, and his "bonus" isn't useful at all--since he picked the goddess, Aqua, herself. How are the two of them supposed to defeat the evil Devil King and live happily ever after? Well, for them, it probably starts with day laboring rather than adventuring. And it's only going to get more disappointing from there! (Source: Crunchyroll)

Ao-chan Can't Study!

Most high school girls would be proud that their father is a famous writer, but Ao Horie’s father is an EROTIC writer, a purveyor of pornographic prose. He’s authored hundreds of dirty books and it has definitely warped his twisted sensibilities. Since Ao thinks that anyone who learns about her father is going to assume that Ao is at least somewhat like her pornographic papa, Ao’s solution is to just not talk to other people, especially boys. All she wants to do is study and get good grades so she can go to a school far away from her family. And that’s why Takumi Kajima is driving her crazy! He keeps trying to talk to her, distracting her, and causing her to think about the kind of things she’d rather not think about…(Source: Sentai Filmworks)
