Haven't been here in a while. The max lewd walkthrough is no longer available?
The google doc was automatically deleted due inactivity. It'd be awesome to see it show up again in some form. The thing is, there's no way to see every scene in a single playthrough. It's probably possible to unlock every h-scene in a single playthrough, but the game is designed in such a way that you haven't seen all the content just because you unlocked every scene. There are mutually exclusive ending events, there are multiple approaches to some lewd events, and Aura's previous corruptions can impact future scenes. Because of this the guide would probably need a significant rework if it were to be as in-depth as it was the last time I looked at it.
