Daa! Daa! Daa!

Miyu is an eighth-grade student whose parents work for NASA and are away for an extended period. Temporarily placed with her uncle, she finds him leaving for India on the first day, leaving her in the care of his son, Kanata. Initially, Miyu expects to stay with only Kanata, but this changes when a UFO lands at her uncle’s house. Inside the spacecraft are a small, cute baby named Ruu and his babysitter, Wannya.
