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'm going. Wait here, Nana-chan.
سأذهب، انتظري هنا يا نانا-تشان
Ich mach das. Warte du hier.
Voy a ir. Espera aquí, Nana-chan.
J’y vais. Attends-moi ici, Nana.
Io vado. Tu aspetta qua, Nana.
Eu vou, você me espera aqui.
Я пойду. Нана, ты подожди тут.
