Ryobe: The Sea

Ryobe: The Sea is a Japanese anime focused on the tales of Ryobe, a young teenager who turned pirate. The series started in the summer of 1993, and is still in production to this day.

Development and Production
In late 1992, Matsuda Mobumasu and Tamura Yasuhide came up with an idea to have a long lasting show about a pirate crew.

In 2017, it was announced that Studio Gallop will leave production by the end of 2017, with Studio Acesky replacing them.

In July of 2018, it was reported by Matsuda Mobumasu that the series will end "by the end of 2019" and that "the series is due course to end very soon". Chaossy left production a few weeks prior to the announcement, when Matsuda Mobumasu returned to the series to write.

25th anniversary special
Matsuda Mobumasu returns to the show to write the 25th anniversary special that aired on July 8, 2018. This episode was the last to be directed by Chaossy, as he left production of the series to focus on original series.

Captain's Log
In March of 2004, Disney approached Ryobe Production Team (RP) to create a spin off using their Pirates of the Caribbean characters and settings, which they accepted and RP appointed Magic Bus and Pierrot to animate the series, which was 75 episodes airing from December 2004 to March 2006. In Japan, it was released as Captain's Log, while in other countries, it was called Captain Jack's Log.

Virgin Islands: The Adventure
After their contract with Disney was up, RP split into two, with one focusing on spin offs and the other focusing on the main series. RP appointed Sunrise and Pierrot to animate a new 26 episode series focusing on the Virgin Islands with a new cast. It first aired in July of 2006 and ended in early December of that year.

Ryoma & Akko: South China Sea
After Virgin Islands ended, RP contracted Magic Bus again with Manglobe and Sunrise supporting the animation to make a 104 episode series called South China Sea airing over the course of two and a half years, from April of 2007 to August of 2009.

Ryobe - Close to the End
In January of 2010, RP announced that a spinoff, 'Close to the End, will air in December of that year and will run for 13 episodes. Manglobe and Magic Bus were contracted to animate the spin off.
