A tranquil tale about two boys from very different upbringings. On one hand you have Kai, born as the son of a prostitute, who's been playing the abandoned piano in the forest near his home ever since he was young. And on the other you have Syuhei, practically breast-fed by the piano as the son of a family of prestigious pianists. Yet it is their common bond with the piano that eventually intertwines their paths in life. (Source: KEFI)

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.

On a mysterious night that seems to last for a year, an ordinary college student continues to chase one of his underclassmen, a girl with black hair—the girl of his dreams. Up until now, he has been relying on a simple plan, which is to calculatingly bump into her every day while making it seem like a meaningful coincidence.

Meanwhile, the black-haired girl believes that everything is connected by fate and endeavors to experience as many new things as possible, leaving it all for destiny to decide. While strolling along the lively streets of Kyoto, she discovers that the very beginning of her fateful journey—a book she had as a child—is currently being sold in a second-hand bookstore. Upon knowing this, the college student eyes another opportunity to run into her by chance: this time, he hopes to get the book before she does and finally grasp the thread of fate that could connect their hearts.
