Jinrou Game has about series of 9 books. There's still Jinrou Game: Prison Break, Lovers, Mad Land, Inferno, Lost Eden.
It only got three manga adaptations but movies for each jinriou game series are available under the name of "The Werewolf Game:"
I know this ending was kinda a disappointment so if you want to see the continuation games: https://watchasian.vc/search?type=movies&keyword=the+Werewolf+Game
No commentary on the movies since I haven't seen them.
Nagata Kabi's most recent series called 'My Wandering Warrior Existence' that focuses on marriage also got licensed last week and will be available next year!
