Revy (レヴィ), sometimes referred by her full name Rebecca (レヴェッカ), is the female protagonist of the series. She does most of the fighting for the Lagoon Company. Very little is revealed about her past, although portions can be pieced together through the series. Revy is a Chinese-American born and raised in Chinatown, Manhattan, near Mott Street, spending most of her youth as a thief and murderer. Flashbacks throughout the series reveal that Revy may have honed her skills with firearms by shooting at cans, and that her first murder may have involved shooting an unknown man while using a pillow. It is unknown whether the pillow was used to suppress the noise or to help avoid looking at her first victim.

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).
