Muhyo and Roji visit the home of Shiratori Aya, a client who says a black shadow has been playing her piano at 2:00 AM every night. Muhyo concludes that the shadow is a vengeful spirit born from countless people who envy Aya's talent, but in fact... Later, a package arrives at the bureau for Roji, containing a "magic-sealing pen" and an invitation to take an exam for a promotion to first-class secretary. Then Nana enters with a photo she took of a spirit on a pedestrian bridge...
The spirit traces are gone, too.
اختفت الآثار الروحية أيضاً
Die Spuren sind auch verschwunden.
Los rastros se fueron.
Sans fantôme pour la tourmenter,
elle pourra se remettre au piano.
Sono sparite anche le impronte degli spiriti.
Os traços espirituais também sumiram.
Следы тоже пропали.
