This year's third issue of Kodansha 's Good! Afternoon magazine revealed on Wednesday that Kenji Inoue and Kimitake Yoshioka 's Grand Blue Dreaming ( Grand Blue ) manga will have "big news" in the magazine's next issue on March 7. The manga will have a color opening page and will feature on the issue's front cover.

The official website for the AnimeJapan 2018 convention previously listed that Avex Pictures will introduce a number of new works at the event, including a "new Grand Blue anime." The website no longer lists featured works for Avex Pictures , and Avex Pictures has yet to announce a Grand Blue anime.

Kodansha Comics publishes the manga in English digitally, and it describes the story:

After moving out on his own to a seaside town, Iori Kitahara makes a college debut he never anticipated. A new chapter of his life unfolds, full of diving with beautiful girls and shenanigans with a gaggle of lovable bastards! Idiot-expert Kenji Inoue and au naturel authority Kimitake Yoshioka bring you a glorious college tale filled with booze-fueled antics!

Inoue and Yoshioka launched the manga in Good! Afternoon in April 2014. Kodansha published the manga's ninth volume last October. The manga marks the first time Inoue is authoring an original manga work.
