The official website for the television anime adaptation of Kenji Inoue and Kimitake Yoshioka's Grand Blue Dreaming manga has revealed that the series is officially moving forward with a fourth season. The announcement arrived hot on the heels of the third season's final episode, accompanied by a fresh promotional visual to mark the occasion.
The chaotic college comedy follows Iori Kitahara as he navigates the unpredictable waters of higher education, balancing genuine scuba diving adventures with legendary alcohol-fueled student shenanigans. Created by Kenji Inoue—renowned for Baka and Test—alongside illustrator Kimitake Yoshioka, the original manga has been serialized in Kodansha's Good! Afternoon magazine since April 2014.
Kodansha USA Publishing handles the digital English release of the manga, describing the narrative as a glorious college tale driven by lovable miscreants and beautiful coastal scenery. As production gets underway for the newly confirmed fourth season, fans can anticipate more sun-soaked diving escapades and relentless comedic chaos.
