Notice Regarding the End of Support for Windows 10

We sincerely thank you for your continual support of our company's products.
The following is a notice regarding the system requirements for our PC game software (Windows version).

On October 14th, 2025 (JST), Microsoft will be ending support for the Windows 10 operating system.
Accordingly, our company will also be ending support for Windows 10 on Tuesday, October 14th, 2025.

Should you continue to use Windows 10, you will still be able to play our games for some time after support has ended.
However, there may be cases where games will not run properly due to the application of future updates or automatic updates.
(Automatic updates refers to online games, etc., in which the program is automatically updated when the server is accessed.)

We would like to ask all affected customers to please take note of the support termination date and consider OS migration as soon as possible.

For information regarding the end of support for Windows 10, please refer to Microsoft's website.

If any other guidance becomes necessary, we will provide such guidance as soon as possible.
Thank you once again for your continued support and understanding.
