Japanese anime news outlet Anime!Anime! reported on Tuesday that the theme song performers from the first season of GATE ( Gate: Jieitai Kanochi nite, Kaku Tatakaeri ) will return to perform the theme songs for the second season. Kishida Kyōdan & The Akeboshi Rockets ( Highschool of the Dead , Strike the Blood ) is performing the opening theme " GATE II ~Sekai o Koete~" and the three main female cast members— Nao Tōyama (Lelei la Lelena), Hisako Kanemoto (Tuka Luna Marceau), and Risa Taneda (Rory Mercury)—will perform the ending theme.

Both songs will ship on CD on January 27, 2016.

The anime's second season will premiere in January and cover the "Flame Dragon Arc." Crunchyroll is streamed the series as it aired beginning in July and Sentai Filmworks licensed the series for North America.

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 (voiced by Junichi Suwabe ), they find that the villages in the world are being attacked by a dragon. An elf girl ( Hisako Kanemoto ) who is a survivor from the dragon's rampage joins the group in their travels across the dangerous new world.
