As of Dec. 22, 2015, only two seasons of "Rosario + Vampire" have been produced. The first season concluded on March 27, 2008, and the second concluded on Dec. 24, 2008.
The two seasons of "Rosario + Vampire" produced 26 episodes. The manga upon which the series was based began in November 2007 and concluded in March 2014. The substantial amount of content in the manga that has yet to be animated has prompted speculation of a third season, but no known plans exist for its development. The first two seasons were licensed by Funimation and were released in North America on Dec. 20, 2011.
