The Anime Times official YouTube channel began streaming all 24 episodes of Grand Blue Seasons 1 and 2 for free from July 7 until July 21. The release coincides with the July 2026 premiere of Season 3, allowing viewers to watch the series consecutively. The show is a youth diving comedy known for its drinking and nudity, with warnings at the start of each episode.
Each episode of Grand Blue opens with a text warning that underage drinking is prohibited and that the characters are adults aged 20 or older. The disclaimer is a fixture of the series, which balances scuba diving with heavy drinking and nudity. The free YouTube release of Seasons 1 and 2, totaling 24 episodes, runs until July 21. Season 3 began airing this July, continuing the story of Iori Kitahara and the Peek a Boo diving club. The series is based on the manga by Kenji Inoue and Kimitake Yoshioka.
