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...
It was so long ago, I don't remember.
حدث ذلك منذُ زمن طويل، لذا لا أذكر
Fue hace tanto que ya no me acuerdo.
Hace tanto que ya no me acuerdo.
Je ne me rappelle pas,
ça fait longtemps !
Foi há tanto tempo 
que eu não me lembro.
