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...
can never match up to a prodigy, 
and we're gonna teach them that.
أن يكو ندّاً لعبقري، وسنجعله يعي ذلك
sie können niemals mit einem Wunderkind
mithalten, und das lassen wir sie spüren.
la gente sin talento nunca se comparará
con un prodigio y se lo enseñaré.
non potranno mai eguagliare un prodigio,
e noi glielo insegneremo.
nunca podem se igualar a um gênio,
e você vai mostrar isso a elas.
никогда не смогут угнаться
за одарёнными, и мы им это докажем.
