The TV anime series Shin Koihime Musou: Otome Tairan is the third one in this highly-ecchi fantasy eroge-to-anime franchise, spawned by BaseSon’s adult game Koihime Musou – which re-imagines the characters from the Chinese novel Romance of the Three Kingdoms as “moe (fiery), moe (preciously cute) action love comedy” with an almost all-female cast.

The story takes place at St. Francesca Academy. After the battle between the students ended, they all go to a southern island.
