A bug for non-japanese players

[2024/9/25]
Currently in the game "右手にπを左手に剣を", there is a bug where you cant purchase items properly on the conditions below.
1. non-unicode region setting is not set to Japan
2. region format setting is not set to Japan
These settings can be changed from Control Panel>Clock, Language, and Region>Region and Language.

I'm working on fixing the problem, but it may take some time for the fix update.
Until then, please try changing your region format setting to japanese when you encounter similar problems.
