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 hatred in particular 
generates it in massive amounts.
لكنّ الكراهية بالذات تصدر
قدراً كبيراً منها
und Hass ganz besonders viel.
pero el odio, en especial,
hace grandes cantidades.
mais c’est la haine
qui en génère le plus.
ma l'odio in particolare
ne genera una quantità enorme.
mas ódio, em especial,
gera grandes quantidades.
однако от ненависти
её получается больше всего.
