LOS ANGELES, Calif., June 2, 2025 -- Based on Naoya Matsumoto's hit manga series, Kaiju No. 8, currently serialized on Shueisha's Shonen Jump+ and with over 18 million copies printed and distributed in Japan (including digital editions) across 15 published volumes, the anime Kaiju No. 8 has garnered immense popularity not only in Japan but also overseas, particularly in North America.

◆Original Story Details Finally Unveiled!
Today, during the Kaiju No. 8: Defense Force Boot Camp in Yokohama event, brand-new information regarding the original story of Kaiju No. 8 THE GAME was officially announced.

Mysterious gates known as the Kaiju Dimensional Gates have suddenly appeared due to the actions of a certain Kaiju. In this new Kaiju No. 8 world, where Kaiju with unknown powers appear not only in Japan but across the globe, Identified Kaiju that were once thought to be defeated now confront the Defense Force by passing through these Kaiju Dimensional Gates. On top of that, unknown Kaiju possessing special abilities—and seemingly responsible for the creation of these Kaiju Dimensional Gates—continue to cross over the boundary between dimensions to launch their attacks. Their appearance has led to a series of battles against colossal Kaiju.

In addition, the Closing Order with Zero Restrictions (CLOZER), a newly formed special unit established to investigate the mysteries surrounding the Kaiju Dimensional Gates, has been officially unveiled, along with original character Sagan Shinomiya.
Sagan Shinomiya, the leader of CLOZER, is the adoptive older sister (not related by blood) of Kikoru Shinomiya. This original game character moved to the United States and enlisted in the American Defense Force after being adopted into the Shinomiya family. Although details about Sagan Shinomiya's weaponry and the battles she will face remain under wraps, players can look forward to her key role in the action-packed story ahead.
