・In the New Chapter Event, achieving a score of 300,000 on VERY HARD before meeting the requirements for the mission "Obtain a score of 300000 with 3 or more Shot-attribute characters in the squad on VERY HARD" prevents the mission from being completed.

*As compensation for this issue, we will be sending Dimensional Crystal x100.

Please claim the items from the Home screen > Mail.

*The mail will be available to claim until 2026-01-20T18:59:59Z.

Ongoing Issues

Updated 2026-01-13T07:00:00Z

・In the Shop, the number of Interlude Notes required and the maximum exchange limit for certain items are not set as intended.

Relevant items:

  • ★4 Unimaterial [Caudata-Type Kaiju α]
  • ★4 Unimaterial [Fungal-Type Kaiju β]

Interlude Notes required:

  • Incorrect: 4 per exchange
  • Correct: 30 per exchange

Exchange limit:

  • Incorrect: Up to 50 times
  • Correct: Up to 30 times

*We will not implement a fix for this issue while the Special Event [The Weapon Within] is ongoing. As such, you may continue to exchange these items with the current settings.


・In Stage 13 of Fierce Battle Area [Flurry of the Frontline], Camponotus Honju's actual devour target may be inconsistent with the description for its skill "Voracious Recovery."

*In consideration of the impact on game balance, no fix will be implemented for this issue.

・The uniparts equipped by guest characters may not display on the Characters screen.

*This is only a display issue. The effects activate correctly and can be confirmed in the character's Battle Details during a battle.
