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...
I didn't tell anyone I was a detective,
so cut me some slack.
،لم أخبر أحداً أنّني كنتُ متحرّياً
Ich bitte dich nicht als Kriminalbeamter,
also verschone mich damit.
No dije que fuera un policía,
así que confórmate con eso.
No dije que fuera un policía,

Personne ne sait que je suis
de la police, alors du calme.
Risparmiami la ramanzina, 
non ho detto di essere un detective.
Eu não disse para ninguém
 que era investigador,
