After his father's death, Souta Tawara, a web designer who left his hometown in Kagawa prefecture to live in Tokyo, returns to the countryside where he grew up. His father ran a popular udon restaurant, but with no one to take over, the restaurant has closed down. Inside, Souta finds a child fast asleep in an iron pot—a shoeless, dirty, and absolutely starving child. But when Souta tries to take the lost tyke to the police, the rug rat grows an ears and a tail before his very eyes. This is no ordinary child—it's a tanuki in a human form!

Souta's made his decision: he's quitting his job and moving back to Kagawa, where he'll work freelance while taking care of Poco. What with all the cooking and trying to keep his little charge out of too much mischief, though, he quickly remembers that parenting a small child is easier said than done. Thankfully, he has a "senpai" to turn to in Manabe-san. Can Souta handle a trip to a Gaogao-chan show in Ritsurin Garden with both Poco and Manabe-san's daughter in tow?

When Hiroshi shows up at Souta's house with a hankering for some homemade udon, Souta remembers the recipes his father left behind, so Souta, Hiroshi, and Poco roll up their sleeves and get cooking. But can Souta and Poco keep Poco's secret from Hiroshi when the little tanuki's tail suddenly pops out?

Souta begins to seriously consider what it will take to permanently live in Kagawa with tanuki-boy Poco. He knows it will be easier said than done, but at least his freelance work prospects are panning out with another job from Manabu: livestreaming the local Takamatsu Festival!

Excited by the festival fireworks display, Poco accidentally lets his tail out in the middle of the crowd, in full view of the cameras. Does this spell the end for Souta and Poco's little family...?
