Kaiju No. 8 Game Celebrates First Anniversary With New Story, Character, and 25,000 Crystal Campaign

KAIJU NO. 8 THE GAME has launched its first anniversary celebration, introducing a new main story chapter, a new playable version of Kaiju No. 8, and a series of in-game campaigns that will award players more than 25,000 Dimensional Crystals.

We previously also interviewed Akatsuki Games, the development team of the game, who told us about the game’s goals, original content, and a lot more.

The main addition is Main Story Chapter 14, titled “Kaiju A Disaster: Final Showdown.” The new chapter continues the game’s original storyline as the Japan Defense Force and CLOZER meet in New York for their final battle against the Dimensional Identified Kaiju A.

According to the official story description:

Having sealed the Dimensional Gates across the globe, the Japan Defense Force and the members of CLOZER finally converge on New York for the final showdown. However, Dimensional Identified Kaiju A has at last revealed its true form, driving them to the brink of despair with an unmeasurable fortitude and an infinite horde of spawning Yoju.

Meanwhile, Kafka Hibino faces a crisis that threatens his very existence. Having leapt into the rift between gates, massive transition energy ravages his body. To save him, Sagan Shinomiya steps alone into the rift, but…

Driven by the bonds of camaraderie, humanity ignites the signal for a counterattack. In the wake of this grueling defensive war, can they grasp hold of the future? The final battle against Kaiju A begins as the thrilling Main Story Chapter 14 opens.

Besides the story update, the game has added a new 5-Star character, “[Strike from the Kaiju Dimension] Kaiju No. 8.” The new version of Kafka’s transformed form features a redesigned appearance surrounded by a purple aura, introducing a “previously unseen” power.

The anniversary update also brings back the “[Over Limit] Sagan Shinomiya” pickup banner, along with the 5-Star spear weapon Lc-Anorollal.

To mark the occasion, Akatsuki Games is distributing more than 25,000 Dimensional Crystals through login bonuses and anniversary events over the course of the campaign. A dedicated anniversary website has also gone live, featuring the event’s key visual and information about upcoming celebrations.

A special “Kaiju No. 8 Day” livestream was also announced for August 5. The broadcast will reveal additional content planned for the anniversary and future updates for the game.

Kaiju No. 8 THE GAME is available on iOS, Android, and PC.
