Gokumama: Gokudou Datta Ore ga Mama ni Natta Hanashi

A yakuza who was supposed to have died gets reincarnated as a woman who at that very moment is giving birth!? A single mother who's a yakuza on the inside struggles with raising her first child! A thrilling child-rearing comedy of laughter and tears!
