It's hard to say. Only very roughly and conditionally. Now in the beta version, Celica met three hooligans from the demon king's entourage. A total of 7 are expected. One per version. The interval between versions has recently been approximately 3.5 months. It turns out that the Demon King's route may end in 1-1.5 years. What will happen after that is still unknown. It would be easier if Deimus made not a cartoon, but a regular visual novel. But he likes to do things beautifully.
