That's interesting... I had looked at the 3.5K per volume sales average and thought that it probably hadn't stood out much.
The comparison with Iriya is interesting because A) it predates School Days by quite a bit and B) the love triangle ends up playing out in the opposite direction, with the girls starting out enemies and then becoming friends. I guess the Enomoto's last scene and the general intensity of the last few episodes (the main reason it's one of my all time favourites) have parallels though.
(Also, does "fufu" actually mean something in Japanese? I first heard the term a couple years back but I've never known what it means.)
I'm curious, do you know if School Days had much impact in Japan, or is just English speaking fans who seem to expect a violent end if there's a possessive girl in the harem?
Oh it had a huge impact. In fact, probably even more impact than English speaking fans.
For instance, when something like a love triangle has one of those "OMG" moments, people start singing "Kanashimi no Mukou he."
There are some shows that people state remind them of School Days too, like Iriya no Sora. When it comes to murky, drama-type romance stories, School Days is practically the ruler.
