When Robin's Vespa runs out of gas during a rainstorm, she is picked up by a kind-hearted motorist. Shortly after dropping Robin off, the woman is killed in a horrible accident. Upset over her death, Robin senses that a Witch may have been involved. Together with Amon, Robin pushes forward to uncover the truth.

When two bodies are found apparently burned from the inside out, attention is drawn to Robin; whoever did this has the same power she has. A girl named Aki Yoshioka is the best suspect, but when the STN-J investigates they only find a pile of sand and a confession to killing three people on Aki's computer. Is the team chasing a ghost?

Nagira learns of an artifact called ""The Fragment of Wisdom""; a mystical item that many Witches are now searching for. When he asks Robin about it, though, she claims no knowledge of the object. In spite of her answer, Nagira suspects that she is holding something back from him.

When Nagira brings in a couple to consult about the Fragment, Robin is unnerved by the woman's strange behavior. Her husband later explains that Robin resembles their missing daughter, whom they believe was Hunted by the Factory. Having being brought up without parents, the woman's reaction stirs up forgotten feelings within Robin and she begins to seek a relationship with the couple.
