Enmado Sara no Suiri Kitan S01E06 - A detective who drank poison! What I saw at the end was

Detective Kenji Takebe (Jun Murakami) came to Sara (Ayami Nakajo), the daughter of King Enma. Takebe, who is willing to violence to arrest the criminal, is investigating the murder case in collaboration with his weak junior Morino (Shusaku Kamikawa). It seemed that Takebe's wit had resolved the case, but Takebe was killed by someone stabbed in his abdomen on his way home. At Enmado, Sara told me that the criminal of the last case was a crime, and Takebe eagerly aspired to revive in order to resolve the case. He decides to challenge a detective game.
