This series is currently airing. This visual is supposed to build up for the current arc ongoing in the show (I haven't watched it, so I cannot comment). Check out the ANN article for some additional cast announcements. Synopsis of the series from AniList:
"When was the last time I played a game that wasn't crap?" This is a world in the near future where games that use display screens are classified as retro. Anything that can't keep up with state-of-the-art VR technology is called a "crap game," and you see a large number of crap games coming out. Those who devote their lives to clearing these games are called "crap-game hunters," and Rakuro Hizutome is one of them. The game he's chosen to tackle next is Shangri-La Frontier, a "god-tier game" that has a total of thirty million players. Online friends... An expansive world... Encounters with rivals... These are changing Rakuro and all the other players' fates! The best game adventure tale by the strongest "crap game" player begins now!
