Najica Hiiragi is a noted perfumer for CRI Cosmetics, famous for being able to identify over 500 scents. Secretly, however, she is actually a
field agent for CRI's Intelligence Bureau, an agency unknown to the public and even to most of its own employees for the sake of their own protection. Najica is assigned the mission to recover a
gynoid known as a Humaritt code-named "ZZZ" and referred to as "Lila". Najica becomes suspicious when CRI Intelligence is contracted by Shinba Industrial to recover more lost and possibly rogue Humaritts; especially since most of them are in the hands of criminals, revolutionaries,
guerrillas or terrorist groups. Her suspicions increase when Lila is assigned to be her partner, even though Najica insists she be allowed to continue working alone. As time goes on, however, Najica begins to trust Lila, even if Lila's lack of social graces make her wince. ==Characters==
