After seeing her in a dream, Kazuhito recalls his younger sister Harumi Madoka. His nostalgia is cut short when Akiyama Shinobu's editor Hiiragi Suzuna appears, a massive masochist with huge breasts prone to fantasizing. What's worse, Natsuno is in a slump?! As they discuss how to get over her slump, the subject of a mysterious slasher case arises.
However, lurking in the shadows of the incident are glimpses of Akiyama Shinobu's book and Madoka...
In that case, shall we raise the 
curtain on a pet murder case?
Sollen wir dann jetzt gleich die Bühne
frei machen für einen dramatischen Vorfall
En ese caso, ¿damos por iniciado 
el caso del asesinato de mascotas?
Nesse caso, talvez pudéssemos elucidar um caso
 de assassinato de animal de estimação?
