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.

but I do remember the first time
 he ate dinner with us.

de son premier repas avec nous.
mas eu me lembro do dia 
que ele jantou com a gente.
