My review applies to all ES volumes.

I read it somewhere in my late teens or early twenties, and then it was a favorite of mine both in the sci-fi and romantic manga genree. The core idea was revolving about something I liked to phantasize about in childhood, and one of the protagonists was young woman - a scientist and a rather reasonable person - what more could I dream about?! Also I was hopless romantic then, and ES resonated well with my romantic side.

Even though, I am not sure, if I were equaly amazed, if I had read it 10 years and lots of books later.
