Oh my god, I can't believe it! Haha I though "maybe" people can die at some point, but seeing that... Wow!
By the way, I'm more or less halfway through Arantis's route, so I'll probably "report" about that soon!
Edit: yeah, everyone survived in my playthrough, forgot to mention it, but I guess it seems obvious from my answer. I really didn't want anyone to die if I could avoid it, so yeah...
