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...
That's not something you can 
do just by liking the piano.
هذا ليس شيئاً يمكنك فعله
لحبّك للبيانو فقط
Die Liebe zum Klavierspiel
allein bringt dich nicht weit.
No es algo que puedes hacer
solo porque te guste el piano.
Ton don ne te vient pas
que de ton amour du piano.
Questa non è una cosa che si può fare
solamente perché ti piace il pianoforte.
Não é algo que possa fazer
só por gostar do piano.
Такого не сотворишь одной любовью к игре.
