Your VN shows a lot of promise, buddy. Sole survivor is an interesting niche of start, that I can't remember any other project tackle. But I think, you jumped the gun a bit too early in the prologue.
Personally, I feel it would've been better to have a day play out before the spirit calls to your MC, Fenris. Have him struggle emotionally to properly give the reader some first-hand attachments or sorts before he shares his emotions. And then have the whole car thing play out. I do wanna point out that I really liked that part, by the way. It was a great idea for Fenris to immediately emotionally latch unto the car and then even go out of his way to set up the memorial. It shows his desperation well! Either way, it's a good start and your project has potential.
But please, my guy. It's deities, not dieties. They're not weight watchers. Grammar is otherwise fine. A few odd sentences and typos but nothing bad.

Good job so far, keep up!

Complaining about AI art is like a high-class chef complaining that people enjoy fast food at burger joints.
People use it because it's cheaper and just as usable at a lower quality. In the case of this VN, it's even been edited on top to look better. There's still the oddity of the classroom background, where the chairs and desks face towards the windows. But man, here's someone new trying to share his passion project and someone complains about something so meaningless. I can just imagine artists being upset that a customer isn't using their services, that said customer wouldn't even commission in the first place.
