Singer performed theme songs for TV anime, 2017 film

The official website for the anime films of Kenji Saito and Akinari Nao 's Trinity Seven manga revealed on Saturday that ZAQ will return to perform the theme song for the second film. The theme song is as-yet untitled, but the CD single is slated to ship on February 27.

ZAQ previously performed the opening theme song for the Trinity Seven television anime, as well as the theme song for the Trinity Seven: Eternal Library & Alchemic Girl anime film.

The film will open at Shinjuku Wald 9 in Tokyo and other theaters throughout Japan on March 29.

Yen Press is publishing the manga in English, and it describes the story:

Arata Kasuga transfers to the Royal Biblia Academy to solve the mystery of the destruction that is ravaging the world and that - more importantly - has stolen his cousin Hijiri from him. It's a tough road that lies ahead of Arata, but nothing's impossible when you have seven beautiful girls - each a master of her own magical art - at your side!

Saito and Nao launched the manga in Monthly Dragon Age magazine in 2011. Kadokawa published the manga's 19th compiled book volume on July 9. Yen Press published the manga's 15th compiled book volume on November 13. The manga has more than 3 million copies in print. The manga has inspired spinoff manga, including Trinity Seven : Liese Chronicle, Trinity Seven : Levi Ninden, and Trinity Seven : Seven Days .

The manga inspired a 12-episode television anime series that premiered in October 2014, and Crunchyroll streamed the anime as it aired in Japan. Sentai Filmworks released the series with an English dub on Blu-ray Disc and DVD in August 2016.

Crunchyroll also began streaming the Trinity Seven: Eternal Library & Alchemic Girl film in March 2017. The film opened in Japan in February 2017.
