Unnamed Memory, Vol. 4 (light novel) - Chibi Chibi, Sarah Tangney, Kuji Furumiya

A New History, the Same Destiny Prince Oscar of Farsas, seeking to rid himself of the curse placed on him fifteen years ago, ventures to the thriving Magic Empire of Tuldarr in hopes that its mages might succeed in breaking the spell. Although Tuldarr’s king proves incapable of the task, he claims there may be another powerful enough to help Oscar-a young woman named Tinasha. Despite having been in magical slumber for four hundred years, this proposed savior already seems well acquainted with the prince, even insisting that he marry her! While the pair navigate their unusual relationship, a dark conspiracy grips the land. Tinasha thinks herself the only one who recalls the erased past, but is she truly?
