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...
I haven't done anything wrong,
لم أقترف أيّ خطأ
Ich habe doch nie was Böses getan.
No he hecho nada malo.
Je n’ai jamais rien fait de mal…
Io non ho fatto niente di male...
Eu não fiz nada de errado.
Я... не сделала ничего плохого.
