It has come to my attention that my synopsis for Shuumatsu apparently makes it sound like a generic battle harem LN. I think this is turning a lot of people away and may deter them from giving the anime a try, which obviously we don’t want. I made some minor changes to it and this is what I came up with:
Five hundred years have passed since the humans went extinct at the hands of the fearsome and mysterious ‘Beasts’. The surviving races now make their homes up on floating islands in the sky, out of reach of all but the most mobile of Beasts. However, this new safe haven Regul Aire has a dark secret behind it.
Only a small group of young girls, the Leprechauns, can wield the ancient weapons needed to fend off invasions from these creatures. Into the girls’ unstable and fleeting lives, where a call to certain death could come at any moment, enters an unlikely character: a young man who lost everything five hundred years ago, the last living human awakened from a long, icy slumber. As he struggles to come to terms with his accursed fate and find his place in this hostile new world, he becomes the father that the girls never had. Together, through their everyday interactions in the ‘orphanage’, they gradually come to understand what family means and what is truly worth protecting.
I want to hint more at the father-daughter relationship, as opposed to romantic harem, and also the everyday life aspect, as opposed to fighting. Anyways, if you have any thoughts or suggestions let me know. Once I have something I’m satisfied with I’ll submit it to MAL and such.
