Having given up on life, 15-year-old Hatori Chise sells herself at an underground auction, where she is bought by Elias Ainsworth, a not-quite-human mage, for 5 million pounds. She learns that he intends for her to be his future bride, and her world begins to change.
It's the trail we leave 
after we've passed by.
.إنّه الأثر الّذي نتركه حين نمرّ
Das ist die Spur,
die wir hinterlassen.
Sono le tracce 
che lasciamo al nostro passaggio.
É a trilha que deixamos depois que passamos.
Это след, который мы оставляем за собой.
