The Slayers (1995)

In a medieval sword and sorcery world, there is one mage who is notorious for her power and grace (at least that's how she likes to put it), Lina Inverse. In reality, she is a teenage mage with a penchant for collateral damage, obnoxiousness and gluttony. This series chronicles her adventures with companions, such as the powerful but dumb swordsman Gourry Gabriev as she quests for gold and finds a heck of a lot trouble along the way.
