Mafia's Runt Dog Is a Lop-Eared Rabbit [Crossover]

Nakajima Atsushi (female) finds a lop-eared rabbit. The rabbit has black fur and white ears, a strange temperament, and looks just like a certain beast of calamity. For some indescribable, special reason, she falls for it and decides to spend her entire fortune raising it until its coat is glossy black. From then on, the Armed Detective Agency's lucky white tiger sets out on the road to serving its rabbit master. Akutagawa Ryunosuke turns into a rabbit: a lop-eared rabbit. For some indescribable, special reason, he doesn't run back to the Port Mafia for help. Instead, he goes to the staff dormitory of the Armed Detective Agency. And sure enough, a woman overflowing with compassion carries him away. At first, being kept as a pet is terribly embarrassing, but after a while, he discovers how delightful it is to be doted on by a young woman as her master. Akutagawa Ryunosuke: I think being a rabbit isn't so bad. Until one day, after hearing from his teacher that Akutagawa Ryunosuke has been missing for many days and has almost no chance of surviving, the young woman hugs him and cries. Akutagawa Ryunosuke: I don't want to be a rabbit anymore! I want to turn back! [Reading Guide] 1. Inspired by a famous fairy tale, with a heavily modified take. 2. Atsushi is gender-swapped.
