Hiroya Oku Thunder 3 is no longer a rumor: on September 24, 2026 the Gantz author confirmed on X that Yuki Ikeda is another name of his, kept secret so the first-chapter twist would land.
What happened?
Oku said the chapter-1 reversal would have been weaker under his real name. He thanked the anime staff.
The manga ran in Kodansha’s Monthly Shonen Magazine from May 2022 to June 2026 (ten volumes). Unend’s TV series premiered July 9, 2026 on Fuji TV’s +Ultra block, just before the season finale.
Why it matters
He had used Kuon Yahiro on Hen. The reveal lands as he plans to retire after The Sweet Sixty Princess.
What changes in practice
Authorship is official. The published story does not change; the credit around the twist does.
