LOS ANGELES, Jan. 9, 2026 /PRNewswire/ — Kaiju No. 8 THE GAME, co-produced by Akatsuki Games, TOHO, and Production I.G, is thrilled to announce the new ★5 Character [Ax Technique Proficiency] Soshiro Hoshina coupled with a new Special Event featuring Hoshina and Kikoru testing their limits at the training grounds.

Enjoy a side of the characters beyond the main story, and earn rewards such as a new Home background, up to 1,500 Dimensional Crystals, and more!

◆ Special Event [The Weapon Within] Now Available!

The new Special Event features a story centered on Soshiro Hoshina and Kikoru Shinomiya, showing parts of their daily lives that are usually hidden away from the main story.

The new event, Special Event [The Weapon Within], will begin on January 9, 2026.

The story is set in Tachikawa Base. During a warehouse cleanup, two items were discovered: a Greatsword that was once prototyped as Kikoru Shinomiya’s custom weapon but was scrapped before practical use, and a prototype “Ax” created during the development process for her current custom weapon. When Kikoru Shinomiya visited the Third Division for training, Soshiro Hoshina challenged Kikoru to a sparring match using these weapons.

Hoshina shoulders the Ax while Kikoru wields the Greatsword. As they fiercely trade blows with unfamiliar weapons, Hoshina poses a question to Kikoru that she is “critically lacking one thing”—what could it be?

Keep a close eye on the two going all out during training in this Special Event story!

In this Special Event, you can earn:

• A new Home background
• Up to 1,500 Dimensional Crystals
• The event-limited ★4 weapon “Ax-Bison 91” (Ax)

*Dimensional Crystals can be obtained from quest clear rewards, mission rewards, and from the event item Exchange Shop.

◆ New ★5 Character [Ax Technique Proficiency] Soshiro Hoshina

★5 [Ax Technique Proficiency] Soshiro Hoshina joins the battle in this update!

Soshiro Hoshina is the Vice-Captain of the Japan Defense Force Third Division. A sword specialist, he comes from a family that has been fighting Kaiju since the Muromachi period. Despite his mastery of the sword, Hoshina is also proficient with the ax—and now takes on the role of guiding Kikoru Shinomiya.

What is Hoshina trying to convey to Kikoru by picking up the ax once again? Enjoy the full story in the Special Event [The Weapon Within].
