Kyoto has been populated by groups of tanuki and tengu for years, living alongside humans who are oblivious to the existence of these creatures. Yasaburou Shimogamo is the third son of an influential tanuki family who spends his carefree days taking care of an old tengu, observing humans through his ability to shapeshift, and dealing with the mysterious woman named Benten. Behind the peace and tranquility, however, is a painful memory from long ago as Yasaburou's father, head of the tanuki community, was killed and eaten by a group of humans known as the Friday Fellows. Uchouten Kazoku follows the trials and tribulations of the Shimogamo brothers as they struggle to avoid their own grisly demise while coming ever closer to unraveling the truth behind their father's death.

After uncovering the truth behind their father's untimely death, life for the four Shimogamo brothers returns to relative peace with each trying to live up to their father's greatness in their own way. For the eldest, Yaichirou, who aims to become the next Trick Magister and leader of the tanuki society, it starts with reinstating the popular shogi tournament. For Yajirou, it is restoring his former shapeshifting abilities, whilst little Yashirou is content with continuing his work at the family’s factory. But for the third son, Yasaburou, it simply means embracing the fool's blood he inherited from his father and living a carefree but interesting life. This, of course, includes hunting for the mysterious and elusive snake-like creature known as a tsuchinoko, and causing ripples of trouble at every turn. However, these ripples threaten to turn into waves with the return of Nidaime, the estranged son of the brothers' tengu teacher, Professor Akadama. Nidaime bears a grudge against not only his father, but his father's apprentice Benten as well. His loyalties suddenly brought into question, Yasaburou must use his tanuki wit to appease all sides without getting caught in the crossfire, before the delicate balance between human, tengu, and tanuki is overthrown and all hell breaks loose.
