Her mother, the previous owner of the brothel, had fallen in love with General Cross and decided to become a supporter of The Black Order. The reason she had fallen in love was never revealed to anybody, not even Anita. Sometime after her mother's death, Anita herself had also fallen in love with Cross and had a relationship with him as well, which is why she offers her services to the exorcists responsible for finding him.

After the fierce battle just as Lenalee reached out her hand to Anita she compliments her hair saying it was beautiful and smiles. From this it is suddenly revealed that she was one of those that died in the battle. Upon discovering her death from Lenalee, General Cross states that he had told her not to follow him. A moment before disappearing, she asks Cross whether she was now a great woman, then died from the affects of Akuma blood virus along with Mahoja and the ships crew. When she died it is shown that Lenalee, during their short time together, had now grown to like her and cried along with Miranda as they left her behind on the ship.
