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...
And I've been here all by myself ever since.
وبقيتُ وحيداً هنا بمفردي مُذ آنذاك
Seitdem bin ich ganz allein hier oben.
Y he estado aquí desde entonces.
Depuis, je suis tout seul ici.
E da allora sono sempre stato solo.
E eu estou aqui sozinho desde então.
С того дня я сижу здесь в одиночестве.
