Getsu Fūma Den is a 1987 Famicom game by Konami starring Getsu Fūma. It was released in July 7, 1987 (in Japan only), which was after the original Castlevania but before Castlevania II: Simon's Quest.
While this game has no sequel, several Getsu Fūma Den-based stages have appeared in other Konami games. These stages are set in Hell and appear in Konami Wai Wai World, Wai Wai World 2: SOS!! Parsley Castle and Castlevania: Harmony of Despair.
Relation with the Castlevania series
Characters and stages from this game appeared on DLC for Castlevania: Harmony of Despair. The final boss is Ryukotsuki, which is also the boss of Chapter 11 in the Harmony of Despair stage The Legend of Fuma.
The game generally follows Japanese mythology, but several enemies are similar to, or are the same as those who appear in Castlevania. Some of them were later re-used in the Castlevania series, such as Shimon, known as "Hellmont" in Harmony of Despair, a parody of Simon Belmont and a Skeleton.
