Tony Slayers, Slayers Next, Slayers Try, Slayers Gorgeous, etc. It has average animation style, well-developed characters, and cool magic techniques. The story itself is well-thought. Although not continuous from series to series, the bad guys kinda takes history from the previous bad guys.
Slayers is set in a fantasy world where magic and swords are the main weapons.
Dragon Slave is the main magic here as it creates atomic-bomb type of explosions. The main sword is none other than the sword of Light. She gets the nickname of Bandit Killers and Dragon Spooker not for nothing. Her main magic is Dragon Slave. Oh yeah, she also has high appetite for food and her greediness is beyond comparison.
