This is a bonus episode that knows exactly what it is: thirty minutes of the found family you've already grown attached to, doing nothing in particular. Sora and Raika finally get the screen time the main series couldn't give them, and the chemistry lands because the show earned it through five volumes of actual care. If you watched Papa no Iukoto and wanted more of these people together, this delivers that without pretense.
Pokkapoka is an unaired special episode of Papa no Iukoto wo Kikinasai!, released with the fifth Blu-ray volume of the series. The show centers on Yuuta Segawa, a college student who suddenly becomes responsible for his three nieces: Sora, a fourteen year old middle schooler, Miu, an elementary school girl, and Hina, a three year old in daycare. The four share a small one-room apartment, and their home life plays out as a romantic comedy with a slice of life feel.
