In a peaceful countryside far from the chaos of Yokohama, former mafia executive Chuuya Nakahara and ex–detective Osamu Dazai now run a quiet farm together. Chuuya manages most of the work and the animals while Dazai claims he’s “supervising,” though he mostly naps in the grass. The two raise three energetic children who constantly drag them into chaos. Their farm becomes a gathering place for old friends from the Armed Detective Agency and former Port Mafia members, who visit often—usually bringing trouble, laughter, and far too many animals.
