This is what the main story should have been.
The final part feel like an axe though.
Vamp girl was probably meant to have some other problem before axe happened.
The wolf girl is a total brainless fetish/plot device, the slime is fun though.
At the start it felt like pres was halfway to confessing to MC but then author just left her out of everything, very strange.
The door making ability was very rushed, that might have been when author was told to wrap it up.
So yeah even with multiple things being rushed and weird about the story, it's still better than the original, hah.
