Even after those people were murdered, Daisuke claims that this incident is an internal problem of the Kambe family. The rift between Daisuke and Kato has become so serious that they decide to go their separate ways. However, Kato is apprehended by the First Investigation Division as a material witness. The remaining members of the Modern Crime Prevention Task Force follow the clues about the suspect that Cho-san left behind. Suzue claims to have seen the actual suspect inside the Kambe residence, and clearly states that it was none other than Shigemaru Kambe.
If you run away,
you'll no longer be a detective, nor a hero!
Si vous faites ça, vous serez pas
plus inspecteur que héros.
Se scappi, non sarai più 
né un detective né un eroe!
Se você fugir, não será mais
um detetive ou um herói!
