Investigation officers are not to be trifled with, especially someone like Kaga Keido, an elite leading the First Investigative Division of the Police Department, responsible for commanding local police stations to solve major cases. His rank is at least assistant police chief, which is why this group of gangsters has the patience to bicker with them—otherwise, the 'Young Master' would have already smashed a bottle over their heads.
Similarly, Kaga Keido is also powerless against the Inakawa Association. In recent years, the relationship between the Police Department and local syndicates has become increasingly tense. If accused of 'police assassinating a gang leader', it could potentially spark an armed uprising—the police cannot kill, this is the recognized baseline on both sides of the law, and the foundation of order in this country.
