Magilou is a mysterious young woman who considers herself a "great sorceress" and the Head of an organization called the "Menagerie," though said group is more known for their practice of "unlicensed witchcraft." She has an extroverted, easy-going, chatty and reckless personality, though she can be sinister at times, especially in the way she says heartless remarks toward Velvet. Her chatty personality hides her true intent and her trickster ways, though her heartlessness can sometimes bring out great truths. She can be seen occasionally cruel towards Velvet.
She is a rear-type fighter and is good at fire and water artes. She can also transform her guardian into various forms during battle.
