This is a link to where you can download it's VN's.
This series has multiple VN's, if you decide to start, start with Sekien no Inganock, it follows a travelling doctor who is basically caught up in supernatural events. 10 years ago Inganock, the city, was isolated from the world and the everything went to hell, ppl mutating, illnesses that fuse with your existence, monsters that can't be killed that kill ppl etc.
We follow Gii as he learns about the city and why everything became that way, it's honestly among my fav VN's.
I'll definitely check it out now. Shameless advertising, but the only other VN I can offer you is Danganronpa.
Story follows Makoto Naegi a (near) talentless student that was chosen to attend Hope's Peak Academy, but ultimately ends up to a school of complete mayhem and despair. Each student is forced to participate in a killing game to ensure their freedom, but they must make sure they aren't figured out in a class trial, or they are executed themselves.
That would be surprising since VN fans usually complain about anime adaptations: Maji Koi, 11 eyes, Dies Irae, Rewrite, all garbage adaptations.
It's really not realistic to expect adapt a 50+ hour VN in 12 episodes, that's just insane. They turn Maji Koi into some sort of Harem, Ecchi series, though i have to say i did enjoy it before reading the VN, cause i was into that sort of thing years ago.
