The anime series 'Junjō Romantica' is based on the yaoi series 'Junjou Romantica' by Shungiku Nakamura.
Produced by Studio Deen, the anime episodes follow the on-going Manga series of the same name by Shungiku Nakamura. Premiering in Japan on TV Hokkaido on April 10, 2008, the series' first season ran for twelve episodes until its conclusion on June 26, 2008. A second season premiered on the same channel on October 12, 2008, where it also ran for twelve episodes.
The series uses four pieces of theme music, two opening themes and two ending themes. Pigstar performs both opening themes, with their song "Kimi=Hana" (君=花, lit. "You=Flower") used for the opening theme, and "Shōdō" (衝動, lit. "Impulse") for the second season. For the ending theme, "Baby Romantica" (ベイビーロマンチカ) by Script is used for the first season's episodes, while "Aioi -Aioi-" (相生-アイオイ-, lit. "Developing") by Juned is used for the second.
There is also an OVA that features the three couples.
