North American visual novel publisher and localizer Sekai Project announced at its panel at Otakon on Saturday that it is launching a new manga publishing initiative. The company's first title will be Satoru Sao, Takumi Yanai, and Daisuke Izuka's GATE (Gate: Jieitai Kanochi nite, Kaku Tatakaeri) manga.

The manga adapts writer Takumi Yanai and illustrator Daisuke Izuka's light novel series of the same name. Sao is publishing the series monthly on Alphapolis' website. Alphapolis released the seventh compiled volume of the manga in print on June 25.

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 to the alternate world beyond the gate. Led by otaku soldier Yōji, 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.

The television anime adaptation of the light novel series premiered earlier this month. Crunchyroll is streaming the anime as it airs and Sentai Filmworks will release the series on home video.
