Hiroya Oku

Hiroya Oku will retire with Kairoki Hime, the manga he currently serializes in Big Comic Superior, and he stated on October 12, 2026 that he will draw both Kairoki Hime and GANTZ:E through to the end. Thunder 3, the manga he created under the pen name Yuki Ikeda, finished in June 2026, and its television anime will return for a second season in 2027.

Synthesized from 6 Yomimono stories · updated Oct 16

Hiroya Oku has been the subject of two threads across these stories: the authorship of Thunder 3 and the end of his career. On September 24, 2026, Oku stated on his X account that he is Yuki Ikeda, the credited author of Thunder 3. He said the pen name kept a chapter 1 twist intact, since the Oku name would have lessened the surprise for new readers. The reveal arrived after the manga had already ended and one episode before the anime finale.

Thunder 3 ran in Kodansha's Monthly Shonen Magazine. It launched in May 2022, ended on June 5, 2026 in the July issue, and the collected volumes total 10. The anime premiered on July 8, 2026 on Fuji-TV's +Ultra block and streamed on Netflix the same day, and its second season is set for 2027. Kodansha USA publishes the manga in English. On October 12, 2026, Oku said on X that he will retire with Kairoki Hime, a statement he had made before in posts on February 4 and May 28. In an August 11, 2026 interview with Courrier Japon, he said he plans to retire after finishing Kairoki Hime, citing a lack of energy and stamina for drawing. He said he will draw both Kairoki Hime and GANTZ:E through to the end.

Earlier coverage framed the retirement as the end of a long career and the pen name confirmation as the resolution of reader speculation about art style. The later stories establish the pen name as a stated fact and the retirement as a declared endpoint for two series. No story states a release window for future Kairoki Hime chapters or a date for the second Thunder 3 season beyond 2027.
