The White Cat Project Summer Festival 2025 will be held in five cities across Japan. At the venue, character panels of Kuroka, Shiro, Aisha, Judah, Galea, and Marle, which were specially drawn for the event, will be on display, and original POP UP store merchandise will also be on sale.

At the venue, there will be vending machines where you can purchase label cans featuring original illustrations of Kuroka, Shiro, Aisha, Judah, Galea, and Marle. The cans contain oolong tea, and the labels can be peeled off and kept as stickers. In addition, there may be a limited number of "winning cans" that come with original acrylic key chains featuring the same characters as the label cans.
