>>4866A few things:
First, the game is a parody of Madou Monogatari only because the backstory and some characters appear on it, but that's just about that. Arle stayed pure.
I do suppose that the Peret em Heru reference of a professor is there, but I'm not entirely sure. First and foremost, the students are transported to Satan's castle as a consequence of something unknown (Haven't played since I posted the pics). The professor came by own volition to study some ruins with other 2 students that died; neither party knew the other was there. So while I see that cold come as a reference, it's certainly not the same thing.
And, I don't remember if that guy particularly can be saved, but a few objects can be obtained only if you trigger some events that end in the death of someone, so I'm not entirely sure if it's possible to save them or not as I haven't beaten it yet (been more engaged in the original madou monogatari), but I think a saw some pics in the files that suggest some of those that died in my gameplay don't necessarily die, but I'm not sure if it's because other died or if they can be saved.
