It looks to employ quite elaborate animations and could almost pass off as a new MMO using the IP – something that has happened before in Han-Gyaku-Sei Million Arthur – but the description, and indeed the art shown towards the end of the teaser, indicates that it will be a card game. The production quality implies this is the IP’s way of keeping up with something like Yu-Gi-Oh! or even Shadowverse‘s console outing, Champions Battle.
The last game in the IP was released in 2018, and for the most part, it’s been dormant after the anime in 2019. We won’t know if the game will be made available outside of China or which platforms it will be released on, but keep an eye out.
