Haja no Fuuin (覇邪の封印) was originally developed and released in Japan, and later localized as Miracle Warriors: Seal of the Dark Lord. It is a role-playing game developed by Kogado and ASCII for the PC-88 and ported to the Sega Master System by Sega in 1987. It is one of the earliest Japanese RPGs to be localized and released in the West.
The Japanese release for the game came in a big box with a cloth map and a steel figure. It also made use of the Mark III’s FM Sound Unit add-on for enhanced music (the Japanese Master System had the FM unit built-in).
