It seems the anime "VRAINS" is not getting a manga adaptation.
New Main Character is named Shouma (Breaking the "Yu" Tradition), created by 5D's mangaka Masashi Sato
He uses a "Tenyi" deck, which is an existing Link summoning based deck
The lack of new cards makes me think this is not related to the eventual Generation 7 announcement
Manga is called "OCG Structures",and apparently will focus on using real TCG cards to teach people how to play
Edit:First chapter is already out it seems
