"KAIJU NO. 8 THE GAME," a smartphone and PC title developed by Akatsuki Games in collaboration with TOHO and Production I.G, has revealed key new details: an original storyline and an exclusive game character named Sagan Shinomiya, voiced by Akari Kito.

Based on the hit manga by Naoya Matsumoto, which has surpassed 18 million copies in circulation (including digital), Kaiju No. 8 has gained global popularity. The game builds on this momentum with new narratives and characters not found in the original series.

Original Story Set in a Multiversal Kaiju Conflict

At the event “Defense Force Boot Camp in Yokohama” held on June 1, it was announced that mysterious "Kaiju Dimensional Gates" have appeared across the world. These gates bring back previously defeated kaiju and introduce new, more dangerous creatures with unknown powers. This sets the stage for large-scale battles where players must take down towering enemies in new scenarios.

New Unit 'CLOZER' and Character 'Sagan Shinomiya'

A special unit called CLOZER has been formed to deal with the dimensional gates. Sagan Shinomiya, an original character created for the game, is the adopted elder sister of Kikoru Shinomiya. Raised in the Shinomiya household and later joining the U.S. Defense Force, Sagan leads CLOZER and plays a central role in the game’s new storyline.

Akari Kito Cast as Sagan Shinomiya

Akari Kito has been confirmed as the voice of Sagan. In her video comment, she stated:
"I'm honored to play an original character. Sagan appears cool and composed but is actually very earnest and kind. Recording has been a lot of fun."
