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...
Then the same person put them up
on the wall and at the crime scenes?
هل هذا يعني أنّ المُلصقات في الجدار والمُلصقات
في مواقع الجريمة قد ألصقَها نفس الشّخص؟
Dann sind die an den Tatorten
und an der Mauer
¿Entonces las pegó la misma persona?
Entonces, ¿las pegó la misma persona?
Alors, ce serait le même type
qui les aurait collés sur ce mur
Quindi gli adesivi sui luoghi degli incidenti
e quelli su questo muro
Então os adesivos nessa parede e nas cenas dos
 crimes foram colocados pela mesma pessoa?
