(opening message is copy-pasted)
Since this is a pretty long game and has 6 routes, I’ll be posting the walkthrough route-by-route. I pretty much just translated from a Japanese guide so it should be right.
There are usually 1 or 2 CGs that come from alternate/bad ending choices, but it branches pretty late in the route so I’ll give an indication as to where to make a separate save file.
The choices might give spoilers.
