Ymir is a born again, haunted by the memories of the boy she killed and the past life she once lived. In order to put her mind to rest she must uncover the truth behind her past, even if it means reliving it once, twice, three times more. Along the way she meets a girl who craves to be special; something that her father couldn't be and so much more. This girl's name is Historia, and though the two of them are often at odds their fates are intertwined, both inheritors of a legacy that was too much for one goddess alone to bear.

The Year is 845.

This is the year that a girl reawakens, another fights back, and a third, a harsh mistress, is born.

This is the story of those who are caged no more.

(This is a story where Ymir actually snatches up Historia to save herself. But, it's also a story where Historia is truly humanity's enemy and the most despicable girl in the world. Among other things)
