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...
And it's me and Yuu who 
are doing all the cleaning
وأنا ويو من نؤدّي كلّ أعمال التنظيف
Mir fällt auf, dass seine ganzen
häuslichen Verpflichtungen
Somos nosotros los que nos encargamos
de sus turnos de limpieza.
Somos nosotros los que nos encargamos
de sus turnos de limpieza.
Et puis, c’est Yûto et moi
qui devons faire sa part de ménage.
In realtà è perché io e Yu dobbiamo
fare anche tutti i suoi turni delle pulizie.
E eu e o Yuu que temos 
que fazer toda a limpeza
