Stage 1: Rusty begins the game in the village at night. The streets are overrun with monsters that serve Monte Carlo, including cat women, werewolf soldiers, and giant fleas. The stage boss is a combination of dragon and woman named Thunderclap. Stage Music: Queen in the Dark Night. The regular boss theme is first used here, titled "I'll Destroy your Mind". It is used for the majority of the game's bosses.
Stage 2: Stage 2 is a forest, graveyard, AND mausoleum all rolled in to one. Ghosts, skeletons and zombies roam this area. The boss is necromancer named Angel Kiss. Rusty encounters Gateau here for the first time, and he challenges her to meet him in the cathedral. Stage Music: Silent Cemetery
Stage 3: Rusty enters a cathedral on her way to the castle, as Brian Gateau has challenged her to a fight here. Skeletal monks, soldiers, gargoyles and zombies abound. The boss is a gargoyle named "Bungee Demon". Stage Music: Mysterious Chapel
Stage 4: The cathedral's campanile. Rusty must scale the tower, avoiding pendulum and spike traps along the way. Of course, the tower is also inhabited by ghosts, man eating plants, and other nasties! Rusty fights Brian Gateau for the first time here. But wait, the floor collapses, and... Stage Music: Dead End
Brian has a special boss theme, titled "Rhythm of Dark".
Stage 5: Rusty finds herself in a cave. Quite naturally it's full of monsters, including bizarre trilobite like creatures and leeches (and leech women!)
After avoiding numerous falling boulders and flame-spitting statuary, Rusty takes a ride in a mine cart through a flaming tunnel, which results in a high-speed battle with the fierce spider-woman "Cablegram Stinger". Stage music: "Earth Hole" for the caves, "Hell's Strike" for the fiery tunnels.
Stage 6: The cave leads to a water filled ancient temple. New enemies such as skeletal fish, snake men, and female water spirits are encountered here. The boss is a gigantic, erratically flying snake woman named Screw Driver. Stage Music: Water Gate
Stage 7: Rusty finally arrives at the castle proper. The castle gardens are swarming with monsters, including man eating plants, strange eyeball creatures, and chonchons, the classic flying heads of Mapuche myth. The boss is a giant plant with a series of blossoms named Morning Glory. Stage Music: Red Sunset
Stage 8: Rusty enters the castle to find herself in a clock tower. The auto-scrolling nature of the stage renders the bottom of the screen a deadly bottomless pit! Of course, no self-respecting vampire wouldn't fill the tower with traps and monsters, as well. The boss of the stage is an un-named, gashadokuro-like skeleton. Stage Music: Tower of Destiny
Stage 9: The castle proper, at last! Naturally, this are is crammed with monsters, tricky jumps, and plenty of spikes. Rusty encounters Gateau for the last time here, and mortally wounds him. He presents her with the keys to the inner chambers upon defeat. Stage Music: Stone Washer
Stage 10: At last, Rusty prepares to face Mary and the Count. First Rusty fights Mary, and upon her defeat goes up against Monte Carlo himself. He has two forms, the second of which is a typical large blue demon, rather like another more well-known Count. Upon defeat, Rusty returns Ryoko and all the other rescued girls to the village and wanders off to further adventure. Stage Music: Castle. Monte Carlo, as the final boss, has a unique boss theme creatively named "Final Battle".
