Spike Chunsoft announced in a brief news post on their homepage that Grand Kingdom for PlayStation Vita and PlayStation 4 will soon be removed from sale, and its online features shut down in Japan. The game and its ample supply of DLC consumables will be removed from the PlayStation Store on February 28th with the servers set to close roughly one month later on March 29th.
Regarding PlayStation®4 / PlayStation®Vita version “Grand Kingdom”, the server for Internet communication will be stopped at the end of March 2022. As a result, the online services will be stopped. Thank you for using this product for a long time since its release in November 2015.

Outside of Japan, the same War mode was retired by publisher NIS America in October of 2019. However, the game has remained on sale across Australia, Europe, and North America ever since. At this point it doesn’t seem likely that these versions will also be delisted in the near future. Thanks to everyone who sent in the news today. I’ve added the dates to the Watch List calendar and will have a page up on the site later.
