The anti-heroic protagonist of the series and a third mahai angyo onshi from the fallen kingdom of Jushin. Despite the common perception held by Jushin's former citizens that angyo onshi are virtuous and bearers of justice, Munsu usually comes across as somewhat amoral and does not believe in helping people who refuse to help themselves. When he does help others, his methods almost always involve excessive bloodshed, lying, torture, and other questionable acts.

Dark Schneider is the most powerful sorcerer in the world, which he almost completely took over before being imprisoned in the body of a little boy by Grand (or Great) Priest Geo. Rushe is soft spoken and had a crush on Yoko, which carried over to Dark Schneider. Rushe and Dark Schneider share the same soul, which means they love what each other loves, but that is where it ends: Dark Schneider can be incredibly evil, heartless and lecherous, whereas Rushe is faithful, quiet and friendly. Dark Schneider is immortal (though whether this is conferred upon Rushe is unclear) -- he can resurrect himself through will-power alone. In the English version, he is also called the Mage of Fire, and, in the Japanese, The Exploder Wizard. Whenever Rushe is kissed by Yoko, Dark Schneider is released, and when Dark Schneider is kissed, Rushe is released, and so on, though Dark Schneider can break the seal himself when extremely angry, and he can control Lushe's body at certain times of night (re-gaining his powers for a while in the process).
