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...
Every now and then, we'd meet at
places that gave us some privacy
أحياناً نلتقي في مكانٍ بصفةِ مجهولين
Ab und an trafen wir uns an einem Ort,
an dem wir anonym blieben,
A veces nos veíamos en sitios donde
se es anónimo para intercambiar info.

On se retrouvait parfois
dans des endroits secrets
Às vezes nos encontrávamos em 
lugares onde podíamos ficar anônimos
