Atsushi Nakajima and Osamu Dazai lead the Armed Detective Agency's chibi-sized cast through everyday life in Yokohama, with the rival Port Mafia along for the same shrunken, gag-comedy treatment. Freed from the main series' mystery-thriller plotting, the miniaturized characters trade banter and slapstick across school runs, office chores, and neighborhood outings. This spin-off manga keeps the Bungo Stray Dogs roster intact while trading its noir tone for comedy.
