The last update supported English UI, but the title image was in Japanese, the manual was only in Japanese, and the English support tag could not be added on the sales page.
With this update, the title image has been changed to English and an English version of the manual has been created.
We expect that an English version of the game will be available on a separate sales page in the future, but the contents of the game and included items will be the same as those on the previous sales pages, so please do not purchase the English version separately if you have already purchased the game.
