The April issue of Kadokawa's Monthly Dragon Age magazine (magazine cover pictured at right) revealed on Saturday that Trinity Seven author Kenji Saito and Takunomi. manga creator Haruto Hino will launch a new manga in the magazine's May issue on April 9. The issue teases the manga's story, stating "a door to a new isekai will open."
Saito and Akinari Nao launched the Trinity Seven manga in Monthly Dragon Age magazine in 2011. Saito's other ongoing manga include the Goodbye! Isekai Tensei manga with artist Porabora, and Gishin Eiyuu no Amadeus (Amadeus, Hero of the False God), which Saito launched with artist Ichitaka in Shōnen Magazine R on February 20.
Hino launched the Takunomi. manga in Shogakukan's Manga ONE app in August 2015, and ended the series in June 2018. The manga inspired a 12-episode television anime adaptation that premiered in January 2018. Sentai Filmworks licensed the anime and streamed it on HIDIVE.
