GIGANT is a completed manga by Hiroya Oku, serialized in Shogakukan's Big Comic Superior from December 2017 to September 2021, and it is now set for a theatrical anime film adaptation from K2 Pictures, with staff and cast still unannounced.
K2 Pictures announced at the Cannes International Film Festival on May 17, 2026 that it will produce a theatrical anime film adaptation of Hiroya Oku's GIGANT. It is the company's first animated feature, and the announcement came as part of a slate of projects funded by the K2P Film Fund I, which closed in February after raising approximately 5 billion yen. Staff, cast, and the animation studio have not been announced.
The source manga ran in Shogakukan's Big Comic Superior from December 2017 to September 2021, with the tenth and final compiled volume published in December 2021. It has 1.2 million copies in circulation, and Seven Seas Entertainment published the final volume of its English release in December 2022. The story follows high schooler Rei Yokoyamada and adult film star Papico, who after a supernatural incident can grow to giant size and fights future humans to protect Rei.
Separately, a 2026 Ichiban Kuji lottery line includes a prize named Mobile Suit Gundam THE GIGANT NAME, an unrelated use of the word. No connection between that prize and the Oku manga is stated in the coverage.
