Affected Services

All features and services of "Tsumibatsu Seisenki" will be unavailable during the maintenance period.

At this time, we are unable to provide an estimated time for service restoration. We will issue another announcement as soon as we have further information regarding when the service will resume.

As of now, we have found no evidence of personal information being compromised or leaked from our systems as a result of this vulnerability.

We sincerely apologize for announcing this maintenance after it had already begun.

We deeply regret the inconvenience and disruption this may cause. However, these emergency measures are necessary to protect the security of our services and our players. We greatly appreciate your patience, understanding, and cooperation.

We remain committed to maintaining a safe and secure gaming environment through ongoing security improvements and responsible service operations.
