Virgo

Maid Spirit Virgo. She initially had a contract with Everlue, but after he was arrested the contract broke. She handed her key to Happy and told him to give it to Lucy. She is then called by Lucy to help them out of a situation.

She explains that since she's a spirit, she takes the form that her master desires, so when she was bound to Everlue, she had a big woman form, according to her masters likes. When she is bound to Lucy, she takes a more visually appealing form.
