There's only 3 endings (that I know of), I was expecting more honestly

Healed fuminori ending - I would've liked to see the "real" saya, even though I think I kind of already know how she looks, by just looking how the stuff that doesn't look like her actually look...

Good(?) ending - I almost cried, the first ending I got

Saya dies ending - AKA Koji lives but, at what cost???
