Akatsuki Games, TOHO, and Production I.G released a new update for Kaiju No. 8: The Game adding a new character and a raid battle event.

The new update is available worldwide, adding ★5 [Full-Power Christmas] Kikoru Shinomiya as a playable character in her Santa suit. The new raid battle against Kaiju No. 10 was also released.

Here’s a rundown on the new update, plus a trailer:

★5 [Full-Power Christmas] Kikoru Shinomiya joins the battle in this update!

Kikoru in a Santa suit makes an appearance in the recently released Main Story Chapter 6. Unlike the highly motivated Gen Narumi, Kikoru is reluctant to participate in the Christmas event. Her unusual behavior seems to be deeply rooted in a memory tied to Christmas. Be sure to check Main Story Chapter 6 to discover the memory she holds close to her heart.

This version of Kikoru is a Defender specializing entirely in protecting allies, setting her apart from previous versions of her character in THE GAME. With her Combat Skills and Ultimate Skill, she can provide support such as HP recovery for allies, buff application, and debuff removal.

Furthermore, by acquiring an additional passive skill through leveling up, she gains the ability to revive a single fallen ally. This allows her to support the squad with an even stronger defense.
