Tōka Gettan (桃華月憚, Tōka Gettan?) is a Japanese adult visual novel developed by Root, and published by Orbit, also known for the creation of the Yami to Bōshi to Hon no Tabibito visual novel. The game was released in Japan on May 25, 2007 in regular and deluxe editions. A manga used to promote the game before its release was created and was first serialized in the Japanese magazine Comptiq, published by Kadokawa Shoten, on December 10, 2005. An anime adaptation started airing on April 3, 2007 by the animation studio Studio Deen, and contains twenty-six episodes.
The series is a spin-off from Moonlight Lady, and as such the original name of the game was Tōka Gettan: Moonlight Lady II (桃華月憚 ～顔のない月II～, Tōka Gettan ~Kao no Nai Tsuki II~?). The title was later shortened to simply Tōka Gettan and the subtitle was removed.
