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...
With as much energy as you have at 
Hekihou, it should be easy, right?
ينبغي أن يكون الأمر سهلاً إذا استخدمتِ
نفس كمّية الطاقة التي تظهرينها في هيكيهو، صحيح؟
Für ’ne liebe Seele
von der Hekihō wie dich
Si en Hekihou te ves tan animada,
no te costará.
Si en Hekihou estás tan animada,
no te costará.
Tu as la belle vie
pour le moment à Hekihô.
Sarà facile, per te che alla Hekiho
sei così piena di energie, no?
Se você é tão animada na escola,
 isso deveria ser fácil, não?
