Dude that's ai and not in the game...
To add further context all images are AI in game and are later edited manually by hand for further image clarity, quality and consistency.
There's image are direct from the game files and not currently part of Norah quest. They will be finished and included in 1.8B or 1.9.
While it is fine to dig around in the Unity files for personal curiosity, the mods ask if you do not publish them in the Itch forums. Please delete the image or the post will be deleted by Dr.Muramasa once noticed.
