She is known as "Black Maya" by her ninja clan. Although she is a runaway ninja (for reasons unknown), she still calls herself a ninja from her clan and upholds the clan traditions. One of these traditions is to keep their identity secret, and kill anyone who knows their identity. Kazuya finds out about her identity as a ninja when he discovers her ninja tools.
