Synthesized from 5 Yomimono stories · updated 4d ago

Hiroya Oku confirmed in September 2026 that Yuki Ikeda, the credited author of Thunder 3, is his own pen name. He said on X that the alias protected a chapter 1 twist that his real name would have weakened. Reader speculation about the art style resembling GANTZ had circulated before the post.

The reveal arrived at the end of Thunder 3's run. The manga launched in Kodansha's Monthly Shonen Magazine in May 2022, reached its final chapter in the July 2026 issue released on June 5, 2026, and ran to 10 collected volumes, the last out on August 17. The anime adaptation premiered on Fuji-TV's +Ultra block on July 8, 2026 and streamed worldwide on Netflix the same day, with its final episode, Episode 12, set for September 30.

Days later, the staff announced a second season for 2027. The continuation rests on the adaptation's own standing because the source manga is already finished. Kodansha USA publishes the manga in English.

Separately, Oku told Courrier Japon in an interview that he plans to retire after finishing his current manga Kanrekihime, citing a lack of energy and stamina for drawing.
