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...
It should just attack Aya and be 
done with it, but it doesn't.
عليها مهاجمة آيا وإنهاء الموضوع وحسب
لكنها لا تفعل ذلك
Eigentlich sollte er seine Tat
vollbringen und Aya angreifen,
Debería atacar a Aya y ya.
Il pourrait attaquer Aya,
mais il ne le fait pas.
Dovrebbe attaccare Aya e basta,
ma non lo ha fatto.
Ele deveria atacar a Aya de
uma vez, mas não faz isso.
Он бы просто нападал
на Аю, и всё на том, но нет.
