As far as I know it's random, but if you're on the War path he doesn't get to do anything with Kira even if he catches you with her in the bathtub (or at least he didn't in my game). That was a nice change from previous versions where it seemed like the only way to avoid NTR with Kira was to just skip the bathroom scenes entirely. This might require you to have completed the blackmail event, not sure. Unfortunately the blackmail event takes a random amount of time to do depending on how lucky you are or whether you save scum. So completing that in time to avoid NTR might be impossible without save scumming.Up to the latest update I have avoided being caught by Eric at night with Kira. Can u just avoid it or does that need to happen to at some point get rid of Eric in the next update ? Thanks
There's no way to avoid the lessons with Lisa where both Eric and Ann are there as far as I know, but you can avoid his solo lessons with her. There's also no way to stop him from perving on Alice. The only girl he unavoidably fucks though is Ann.
