This came on TV. What catches the attention the most, aside from the unbearably blue and hopeful, pseudo/post-Ghibli kitsch of modern anime movies, is the most unbearably sweet and positive heroine one can find anywhere, which is exacerbated by how she is supposed to be a semi-realistic character and not a completely artificial cartoon (which would trivially undermine the point).The story is some random nonsense about flying, magically being the best at flying or engineering and having the best summer days ever (forever) and being somewhere between 17 and 21 forever. This may sound familiar if you've ever caught a glimpse of these colourful anime dramas.
