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...

You know we're not supposed 
to meet with past clients.
تعرفين أنّه لا يُفترض بنا
مقابلة عملاء سابقين
Du weißt doch, dass wir Klienten
nicht mehrmals treffen.
No se supone
que veamos clientes pasados.
Sai bene che non possiamo incontrarci
con i vecchi clienti.
Você sabe que não devíamos nos
encontrar com clientes antigos.
Нам же нельзя видеться
с бывшими клиентами...
