THE NEBULA HOUSE

Tamara Johnson has just moved from her old home in Minnesota to Minwa, an island located off the cost of Hokkaido, Japan. It's lonely for her, especially with her parents working overseas and her inability to befriend others despite being fluent in Japanese and other languages, among other things.
But when her pet dog and cat end up missing one day and she goes out to look for them, she stumbles across a weird looking house that houses some even weirder looking residents. Having stumbled into a world of intergalactic affairs, planetary culture experiences and other weird things, Tamara begins to realise that maybe aliens sure are cool, in a goofy, slapstick-like humour sort of way.
