Daa! Daa! Daa!

Miyu is an eighth-grade student whose life takes an unexpected turn when her parents depart to work at NASA, leaving her behind. With no other immediate options, she is sent to live temporarily with her uncle. However, her plans for a quiet transition are immediately upended on her very first day at his home. Without warning, her uncle decides to embark on a trip to India, abruptly departing and leaving Miyu alone with his son, Kanata. Initially, Miyu assumes that her new living situation will simply involve sharing the house with Kanata, but this expectation proves to be short-lived. The ordinary routine she anticipated is quickly shattered by a bizarre and extraordinary event. A UFO suddenly lands directly at her uncle's residence, completely disrupting any sense of normalcy. Inside the mysterious spacecraft, Miyu discovers two unexpected passengers: an adorable baby named Ruu and his babysitter, Wannya. This astonishing arrival transforms Miyu's temporary stay into an unpredictable adventure she never could have imagined.
