Oni III - Kuro no Hakaishin — About this game
ONI III: Kuro no Hakaishin begins with a forbidden storehouse and an opened seal, then follows different heroes through connected chapters. Explore villages, listen for the next lead and prepare equipment before command-based battles carry the party farther from safety. Transformation offers another way to fight, but the characters' separate abilities still give each a role. The consultation command helps keep the party's concerns close at hand, while the system menu provides a place to record progress before another difficult journey.
