The Metropolitan Police Department is struggling to investigate a series of murders, yet Detective Isshiki is ordered to go home. Kiku of the General Affairs Division sends him to meet a certain sleuth—a shaggy-haired eccentric named Kamonohashi Ron.
And there haven't been any significant 
developments in the investigation.
.ولم نُحرز أي تقدم في التحقيق
Es gab keinen nennenswerten
Fortschritt bei der Ermittlungslage.
Et l’enquête
est toujours au point mort.
e non ci sono stati
grandi passi avanti nelle indagini.
А расследование так и не сдвинулось
с мёртвой точки.
