On July 1, 2019, Crunchyroll Games announced a brand-new mobile game will be coming to iOS and Android!
Players will participate in "3D RPG-action", assembling a team of characters from the anime and featuring the original voice actors.
It appears that the game had a beta release in Japan and China several months ago. Here is a gameplay video from the JP version of the game.
