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...
but its actions are too methodical 
for a vengeful spirit.
لكن تحرّكاتها محسوبةٌ كثيراً
بالنسبة لروحٍ مُنتقمة
Aber für einen Rachegeist wirken
seine Handlungen zu kalkuliert.
pero sus actos
son muy metódicos para uno.
Mais il réfléchit trop,
pour un fantôme du genre.
ma le sue azioni sono troppo metodiche.
mas as ações dele são metódicas
demais para um espírito vingativo.
но для мстительного духа
он действует слишком методично.
