Every one hundred years, the forces of evil mysteriously start to weaken. Though some of these evil creatures band together to counteract this weakness, many of them are still slaughtered by the forces of good. But one day, One, the most evil one, found a way to break this curse and grow only stronger and stronger. Sensing the presence of a cure within the blood of a young woman, he pulled her into the darkness...right before our hero's eyes! Filled with anger, he grabbed his mystical whip and followed One through the night until finding himself at the base of One's fearsome castle. What evil awaits him there? Will he save the girl in time?

The goal in each level of this MSX homebrew game is to find the cleverly hidden white key and use it to open the door to the next level. There are also items that can be picked up along the way to help our hero in his quest.

In this run, scrimpeh manipulates enemy movement and utilizes damage boosts and invincibility frames to beat the game in under 9 minutes.

For another MSX game with very similar gameplay, see the run of Vampire Killer done by the same author.
