The "Baki" series continues to grow: The spin-off manga "Baki Gaiden: Retsu Kaioh wa Isekai Tensei Shitemo Ikko ni Kamawan" ("Baki Gaiden – Retsu Kaioh Doesn't Mind Being Reborn in Another World") is getting a TV anime adaptation. The people in charge announced this at the end of August and simultaneously released a first teaser announcement.
The source material originated from an idea by "Baki" creator Keisuke Itagaki; Sai Ihara is responsible for the story, and the illustrations are by Eiji Murai. The manga has been serialized in Akita Shoten's "Monthly Shōnen Champion" since the December 2020 issue. The focus is on Chinese martial arts legend Retsu Kaioh: The fan favorite loses his life in the fourth series "Baki-Dou" in a duel against the legendary swordsman Musashi Miyamoto – and awakens shortly afterward in a medieval-looking fantasy world. There, he wants to prove that Chinese martial arts are the strongest even against swords, magic, and the mighty creatures of the foreign world.
The unusual genre mix of "Baki" and isekai fantasy has proven to be a sales success: By August 2026, the series surpassed the mark of two million sold copies (print and digital combined). The 17th volume will be released on September 8, 2026. Additionally, a stage adaptation titled "Baki THE GRAPPLER STAGE Gaiden" has already been announced, scheduled to take place from March 19 to 22, 2027, in Tokyo.
TMS Entertainment is once again responsible for the animation of the TV series, the studio that already produced "Baki", "Hanma Baki", and "Baki-Dou". A specific broadcast date is still pending; 2027 is mentioned as the time frame. In the ongoing anime series, Retsu Kaioh is voiced by Rikiya Koyama.
Parallel to the announcement, there was more news about the current anime: The second cour of "Baki-Dou", previously available exclusively on Netflix worldwide, will start on October 4, 2026, on Japanese television. It will be broadcast on TOKYO MX, BS Nittele, Sun TV, KBS Kyoto, TV Aichi, HTB Hokkaido TV, and TVQ Kyushu Broadcasting, among others.
