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...
Although he got jealous of my talent 
and ran off to the dark side.
رغم أنّ الغيرة من موهبتي قد تملّكته
وهرب للجانب المُظلم
Pero se puso celoso por mi talento
y huyó al lado oscuro.

Ma poi divenne geloso del mio talento
e passò al lato oscuro.
Apesar de invejar o meu talento
e ter fugido para o lado negro.
Однако он мне завидовал. Поэтому
в итоге переметнулся на тёмную сторону.
