Grim Guardians Demon Purge is a dark metroidvania with a confusing plot. The story tells how two sisters must go on a dangerous campaign against the forces of darkness. The fact is that the sisters are not ordinary girls, but professional demon hunters. Therefore, they have the necessary skills to figure out why their home school turned into a castle where evil lives. Together they will have to overcome many obstacles and defeat hundreds of enemies in order to finally get to the bottom of the truth. This is not so easy to do, because the entire area is teeming with terrifying monsters and traps, but the ladies have special abilities to annihilate them.
