About Grand Blue
Grand Blue adapts Kenji Inoue's comedy manga about Iori Kitahara joining the Peek-a-Boo diving club at Izu University. Season one aired 12 episodes in summer 2018 from Zero-G, covering Iori's arrival and the first diving license tests. Season two aired in 2025 from the same staff with the cast chasing certifications and festival chaos.
The manga continues past both seasons with the story still active, so further anime stays possible with no date announced as of 2026. Both seasons keep the same voice cast and the half-naked party gag rhythm intact across the seven-year gap.
Good to know
Watch season one then season two in broadcast order, since the club hierarchy and Iori's diving progress assume sequence. The show is a drinking comedy first and a diving anime second, so expect more parties than reefs. To continue past the anime, pick up the manga around the early festival volumes where season one closes and season two picks through.
