An entry in the the adventure game series that originally followed the Japanese schoolgirl-turned-otherworldly warrior Yuko Ahso. Part IV passed the sword to new warrior girl Rena. The TG-16 version carried on the three-character set-up of part III, but the "Super" SNES version dropped this feature. The SNES version also had altered graphics (some for the better, some for the worse), different stages, a different type of magic meter system, new and replaced attacks, and an unfortunate lack of cut-scenes besides the animated intro.
