Before being hired for G. I. Unit: 5, Lea was a PI. Meia, her assistant and also a future G. I. Unit: 5 member, was on a case with her. A landlady, Roberta Flemming thought that the man paying rent at her house, Buruusu Zane, might be a criminal. She had overheard Zane talking to a mysterious man over the phone. They had been talking about classified information and Flemming was hiring Lea and Meia to investigate. It wasn't long before G. I. Unit: 5 head, Lief Jackman contacted Lea. He told her that Zane was an assassin, and that the only way she could investigate further would be to join G. I. Unit: 5, otherwise they would have to erase her memory. Lea agreed to join as long as Meia could join too. Though a private detective and good at solving crimes, Lea spends most of her time studying animals. Before a PI Lea was a Zoologist.
