I want to know next update would be for vampire route or main route , and when we can expect it ?
The next update will add a new side quest contract and an extension to Viviene's playable bad ending plus some extra boss fights. The following update will be the chapter 4 update for the main route. As I am getting close to the end of the main route, I will be putting the vampire route on Hiatus until the main route is complete. I usually takes me about 3 months to get everything done on an update, so that's a rough timeframe for when you can expect new content to drop.
