Other name: 終末なにしてますか？忙しいですか？救ってもらっていいですか？; What do you do at the end of the world? Are you busy? Will you save us?;
Summary: Five hundred years have passed since humanity went extinct at the hands of the fearsome â€œBeastsâ€. Even up in the sky, where the surviving races dwell on floating islands, these monstrosities constantly threaten to bring death and destruction. Only a small group of young girls, the Leprechauns, can wield the ancient weapons needed to defeat these creatures. Into the girlsâ€™ 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.
