They Were 11! is an epic science fiction manga from early in Moto Hagio’s career. According to Wikipedia, it was "serialized in three issues of Shogakukan’s Bessatsu Shojo Comic magazine in 1975. The following year, it won the 21st Shogakukan Manga Award in the combined shojo and shonen category. The series has inspired a live-actiontelevision film, an anime film, multiple stage plays, and an audio drama CD."
It has now – at last! – been published in an English in this very nicely done, larger-than-usual-for-manga, 288 page softcover published by Denpa at a quite attractive price point, all things considered.There is a massive preview up on Google Books, HERE. Check it out!
