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...

Las de los otros casos también.
Et aussi ceux trouvés
sur les scènes de crime.

degli incidenti avvenuti finora.
E com os adesivos nas 
cenas dos crimes também.
