What New Fist of the North Star: The Forbidden Fist is
You wake in the ruins of The Last Land where Kenshiro sealed the gates of the underworld. Sara tells you of a dying boy, Lord Doha, and a serum hidden beyond Cliffland. The safe route takes four days round trip and he’s already running out of daylight. You step onto the haunted cliff path anyway. Just as the demons begin circling, another warrior cuts through the mist vowing to claim his lost kin’s fate.
