After Takuru is taken in by the police, Kurusu wants him to give up the case. But he's noticed something... the sumo stickers that have been placed all around town have something in common with the murder scenes.  He puts up a hidden camera near a wall of sumo stickers that just appeared. But when Kurusu finds out, she leaves in the middle of the night to take it down...
In the best-case scenario, we get a lead
on the killer before anybody else.
في أفضل الحالات، يمكننا أن نسبق الجميع
في الحصولِ على دليلٍ يقودنا للقاتل
Falls unsere Arbeit Früchte trägt, kommen
wir dem Täter zuvor und stellen ihn bloß …
Con suerte, tendremos una pista
del asesino antes que nadie.
Con suerte, tendremos una pista
del asesino antes que nadie.
Dans le meilleur des cas,
on démasquera le coupable.
Nel migliore dei casi, ci faremo un'idea
del colpevole prima di tutti.
Na melhor das hipóteses, conseguiremos 
uma pista do assassino antes de todo mundo.
