New ★5 Gen Narumi Joins the Battle!

LOS ANGELES, Dec. 1, 2025 /PRNewswire/ -- Kaiju No. 8 THE GAME, co-produced by Akatsuki Games, TOHO, and Production I.G, is excited to announce that Main Story Chapter 6: Operation: Reclaim Christmas Eve and the new ★5 character [Japan's Strongest Santa] Gen Narumi are now available!

◆ Main Story Chapter 6: Operation: Reclaim Christmas Eve Now Released!

As part of the Defense Force's public relations activities, an annual Christmas event is held to deliver presents to children. This tradition has been upheld by the First Division since before Former Director General Shinomiya became its Captain. The First Division continues to keep the tradition alive, but this year, members from other divisions are joining as well.

Among the First Division members, Gen Narumi puts on a Santa suit, while Kafka dresses up as a reindeer. As they are exchanging jolly smiles with children, a Dimensional Gate suddenly emerges along the coast of Tokyo Bay. While the First Division is busy tackling the Dimensional Gate, the Third Division, led by Akari Minase, rushes in to support.

Meanwhile, Kikoru is troubled by the sudden mission, as memories from a long-ago Christmas resurface. A holiday she was supposed to spend with her parents, a night filled with broken promises that still lingers in her heart.

A peaceful mission of distributing presents intertwines with the sudden Dimensional Gate emergence, Operation: Reclaim Christmas Eve. With each of their hopes held close, they rise up to protect the smiles of the children and the city.
