I completely enjoyed this! it was a long time since i saw it in animax for the first time.
i think i'll look for the manga and see if there is a continue ^^
There will most likely be a second season since the manga have season 2/3 - but as Ssskk sayed, it will take some time, hopefully late 2012 or early 2013.
How can it end at this point?!, is there another anime season?, maybe the next parts in manga at JManga, at least?. There is much more story in the manga. What a great ending, everything so mature and beautiful. Thanks, Crunchyroll!
