Lufa

Mink's best friend. She is an elf with wonderful healing powers, but she is bad at magic and has absolutely no skill with a lightning cane — she usually hits everything but the target.
She has an extremely sadistic personality and is quite unmoral and untactful, often making fun of the misfortune of others and receiving pleasure from causing it. Lufa also has a strong sex drive, making advances onto nearly every visually attractive person she comes across, including several females beside Mink. She becomes a human at the end of the manga, having been turned into a toad by Azetodeth and then drinking the People/Pido Potion. As a human, she can no longer use magic.
Her original name is Rufa, but due to the nature of translation, both Lufa and Rufa are used (though Rufa appears to be the more correct one). In the manga, she has a father named Link. She never mentions her mother, although later on, Link is seen with a female elf who is either Lufa's mother or a girlfriend.
