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...
Look, I know I suck at this stuff, 
but I'm studying, little by little.
اسمعي، أعرف أنّي لستُ بارعاً في هذه الأمور
لكنّي أدرس شيئاً فشيئاً
Du hast schon recht.
Lo sé. Apesto en esto,
pero estudio poco a poco.
OK, je ne suis pas très fort,
mais je progresse à mon rythme
lo so che sono una frana in queste cose,
però sto studiando, piano piano.
Olha, eu sei que sou péssimo com essas
coisas, mas estou estudando pouco a pouco.
Ну и что. Да, я отстой в этом деле,
но я понемногу учусь.
