Two kids become adoptive parents to a UFO baby that crashes to earth.
It made it to some European countries, but for an English version you’ll need to go with fansubs. In the same way that director Hiroaki Sakurai would capture the manga aesthetic of Cromartie High in its anime adaptation, he really gets the aesthetic of both Mika Kawamura’s manga, and the general aesthetic of shojo aimed at that middle school demographic.
Watched the first episode, there’s lots of narrative elements you can see that appear in a lot of these series – heroine’s world turned upside down, heroines expectations of how the world should work thwarted, forced to share space with a “horrible” boy – these all sprung to mind as elements I’ve seen before, but also make perfect sense for the age range it’s aimed at. There’s also a nice line in absurd humour, mainly provided by the sitter-pet, Wannya. In particular, the tale of how Wannya and the baby got to Earth, takes a huge sci-fi concept and reduces it down to something incredibly mundane. It’s great.
