Never.
Rosario + Vampire does not have a third season.
After they write and air season 3.
Yes I think it did because Rosario plus Vampire capu2 (the second season) and the first season were aired all through out 2008. So i don't think they would make a new season 3 years later. To check out all the details go to this Wikipedia page. http://en.wikipedia.org/wiki/Rosario_%2B_Vampire
No it is not Manga i just started reading 2 days ago and it is much better then the anime. go to www.onemanga.com and give it a shot.
Rosario plus vampire has no English game in fact it has English in you tube
the rumoured start date of the 3rd season (1st October) has past so if it doesnt come out soon i doubt there will be one. but heres hoping
No there is Not.
Her father in the episodes, her mother in the manga.
yes Rosario+Vampiers season 3 might come out because there has to be something between the two main character's. also season 3 might come out next month or the month after and today is 2-11-11. so it might come out in march or April so hopes for all!!!!
From what sources say, the anime is officially finished... but about the manga... probably there won't be any more.
Rosario + Vampire and Rosario + Vampire Capu2 has 26 episodes : 13 episodes in two series .
