This show sucks, but I can't stop watching. It's like a (sorta) work-safe version of Bible Black, but from Shounen Jump instead of some eroge studio.
Interestingly, Tsukune is better than most harem protagonists (like Ninomiya-kun, oh gosh oh gosh ><) but he still falls flat pretty royally, though he gets better later on in the manga.
I'm not one for anime fanservice/"hentai"/nudity whatever, but that ED is incredibly hot. When I saw it I was utterly surprised at how unabashed it was; there hasn't been stuff like that since the good ol' days of Mahoromatic, and I doubt R+V is on a late night slot like Geass. They're really pushing the line!
My favourite character thus far is the GAR Bus Driver. He's probably the Devil himself out to groom Tsukune to be some kind of Demon King or sumthin'! Tsukune when he gets manly is also a cool character as well.
Among the girls, I hate bubble-head Moka and the equally ditsy and frankly hideous succubus. I sort of liked Yukari at first, but then i found out she was eleven years old (@_@) and stayed away. So that leaves me with the icy girl, Shirayuki. Everyone loves her, though, so this doesn't set me apart from the crowd.
Pretty formulaic show though. High budget, surprisingly so for such a low-key cocktease.
