The university hangover of Iori Kitahara and friends is far from over. Just a day after airing the final episode of its third season, the animated adaptation of Grand Blue Dreaming surprised everyone by confirming a fourth season in production, along with a great promotional image to build excitement.

The third season’s finale left audiences wanting more after taking the club’s adventures outside Japan for the first time, setting its wild days in the paradisiacal beaches of Palau. While the production team hasn’t revealed the exact return date or plot details, the news was met with huge enthusiasm, especially from those fearing a long wait between seasons.

This quick announcement of new episodes has become a recent trend for the franchise. After a multi-year gap following the original’s 2018 debut, the series picked up speed from 2025, releasing episodes nearly consecutively, proving that the comedy about drinking university students who occasionally remember they’re a diving club is more alive than ever.

About Grand Blue Dreaming

Written by Kenji Inoue and illustrated by Kimitake Yoshioka, the original work began in Kodansha’s Good! Afternoon magazine in April 2014. The story follows Iori Kitahara, a young man who moves to a coastal town for university while staying at his uncle’s dive shop. What promised to be a peaceful school life filled with beautiful girls turns into a spiral of chaos, absurd nudity, and rivers of alcohol with a group of quirky classmates.
