The magic was running out. Oh, Wyrds had worried about it before. Wyrds were always saying the magic was running out. no one listened to them. Or if they did, they stopped listening to them after the magic kept coming and didn’t run out after all. But this time the magic really was running out. Their magic was at the limit set by the laws of physics. Their civilization was old enough and smart enough that all fixable problems were fixed. It was the problems they couldn’t fix that kept coming back to haunt them.

The problem was they were all going to die.

UNLESS.

They did have one hope — a very tiny chance that other Choice Givers existed somewhere else and could be reached.

Kotone, Shiori, and Chiharu had no idea how drastically their lives were about to change. One day they were normal, thirteen year-old girls, content to go to class and spend time with each other. The next day, they were faced with the greatest responsibility of all time: not just saving their own futures or the future of the world — but saving the future in general.
