This card is based off the protagonist of the Japan-only Famicom game released by Konami in 1987, Getsu Fūma Den. The last boss, "Ryu Kokki", is also a card and has a similar effect.
This card is similar to "Vampire Hunter"; they are both Level 4 DARKWarrior-Type monsters that destroy evil monsters through their effect (this card destroys Zombies and Fiends while "Vampire Hunter" destroys DARK monsters). They are also both based on Konami game characters.
However, their effects activate at different times. This card destroys the opponent's monster at the end of the Damage Step, while "Vampire Hunter" destroys them at the start of it.
