No, Black Lagoon Season 4 has not been confirmed. There are no official announcements from studio Madhouse or creator Rei Hiroe about a new season or a potential release date as of September 2025. The lengthy silence since the Roberta’s Blood Trail OVA finished over a decade ago points to the series remaining on indefinite hold, despite a passionate fanbase and available source material from the manga.
Been a long time, hasn’t it? The roar of the PT boat and Revy’s dual Berettas have been silent for what feels like an eternity. After pouring hundreds of hours into the anime, the manga, and every bit of news that trickles out, the question of a fourth season is less about “if” and more about “why not?” The answer is a complicated mix of studio issues, source material pacing, and the personal health of the creator himself. Let’s break down what’s really going on with Roanapur’s most infamous mercenaries.
Is Black Lagoon Season 4 Actually Confirmed?
No. Anyone telling you otherwise is dealing in rumors. There has been zero official communication from Madhouse, the producers, or the creator, Rei Hiroe, confirming that a fourth season is in production. The anime world has seen miracles before with long-dead franchises returning, but for now, Black Lagoon remains stuck in anime limbo.
So, Why Hasn’t a New Season Happened?
The reasons are layered. The primary issue has been the sporadic release of the source material. The anime adapted the manga very faithfully, but creator Rei Hiroe has worked at an inconsistent pace. Furthermore, there are whispers within the community about the state of the original animation studio, Madhouse, which has seen significant staff changes since the anime’s heyday, leading to questions about whether they still have the same team or interest to bring the series back.
Is There Enough Manga Material for Season 4?
Yes, absolutely. This is the most frustrating part for fans. The anime, including the Roberta’s Blood Trail OVA, adapted up to Volume 9 of the manga. As of now, the manga is up to Volume 13, with new chapters slowly being released after a recent hiatus. This leaves at least two major, fully completed arcs ready for adaptation, which is more than enough content for a 12-episode season.
The Creator’s Health Is A Major Factor
It’s no secret that the manga’s creator, Rei Hiroe, has publicly discussed his long battle with depression. This has understandably affected his ability to work consistently on the manga for over a decade. While he has expressed his firm intention to finish the story, his health is the priority. The manga recently returned from a hiatus in July 2025, which is a fantastic sign, but the pace will likely remain deliberate.
What Would Season 4’s Plot Be?
If a new season were to follow the manga, it would likely dive into the arc “The Wired Red Wild Card.” This storyline focuses on a group of elite hackers and plunges the Lagoon Company into a world of cyberterrorism, espionage, and a deadly new antagonist named Feng Yifei. It’s an arc that deeply explores Rock’s continued descent into the criminal underworld and his evolving, complicated relationship with Revy.
The Madhouse Studio Situation
Madhouse was at the peak of its powers when it animated Black Lagoon, but the studio of today is not the same. Many of the creative talents who worked on iconic 2000s anime have since moved on, some even forming studio MAPPA. While Madhouse still holds the rights, it’s unclear if they have the passion or the right team to recapture the original’s gritty, kinetic energy. A new season would need to be a true passion project, not just a cash grab.
Where Can I Binge Black Lagoon While Waiting?
Thankfully, you can still experience the masterpiece that is the first two seasons and the OVA. The entire animated saga of Black Lagoon is currently available for streaming on Crunchyroll. Watching it is the perfect way to refresh your memory of its greatness and show that there is still a massive, active audience for this incredible series.
Will We Ever See Revy and Rock Again?
After all this time, I still believe so. The fan demand has never died, and the source material is there and continues to grow. The creator is back to writing, even if slowly. It might not be with Madhouse, and it might not be next year, but the world of Roanapur is too rich and its characters too iconic to be left gathering dust forever. The return of other classic series gives me hope that one day, we’ll hear the opening theme kick in one more time.
