Car Explosion Case

The Car Explosion Case is a case forwarded to the agency regarding a car explosion that occurred in the middle of its journey.

Prologue
Minoura and his new subordinate arrive at the agency office for a request. Kunikida tells Atsushi to take on the job together with an agency member which is Kenji.

Case
Kenji and Atsushi arrive at the scene. After evaluating the explosion, the two sets off to gather information at a shopping district that may be related to the case. During their info gathering, they were approached by Kenji's friend to which Kenji asks if he know something about it. Kenji's friend reveal some information he heard from someone and apparently there were some guys buying huge loads of fertilizer in a factory district back-alley, specifically nitrogen fertilizer. This led to Kenji's conclusion that the fertilizer are used to make bombs.

After getting a lead, Kenji and Atsushi go to a spot used as a gathering point for a young men's association. They eventually arrive at the gang's hideout. Kenji proceeds to directly ask the gang members if they were the ones responsible for the car explosion to which the latter denies. After hearing their response, Kenji thanks them and the two of them leave. Bewildered by what just happened, Atsushi insists that they may be the culprits, to which Kenji replies that they didn't know about it and his approach - to be kind to others and they'll respond in kind - has yet to fail him. Atsushi just agrees and the two set off to visit a beef bowl place.

Resolution
After their investigation, they were cornered by the gang members they asked a while back. The gang members reveal that they didn't expect the detectives to sniff them out. Kenji give them his thanks for revealing themselves as the culprits, and tells Atsushi that in all of his cases, all culprits ended up confessing to him. Confused by Kenji's statement, a gang member attacks Kenji. However, Kenji immediately stands up with no harm received and attacks all the gang members- leaving all of them unconscious, much to Atsushi's shock.

Manga and Anime Differences

 * In the manga, Minoura originally asks Kyōka Izumi if she was an agency member and Yukichi Fukuzawa telling him that she is his granddaughter. This is not adapted in the anime.
