Seven Seas Entertainment licensed the manga for English print and digital release under the title The Barbarian’s Bride. It describes the main premise as:
Serafina de Lavillant, the strongest female knight in the West, was sent to subjugate the barbaric tribes of the East. But when her mission fails spectacularly, she’s captured alive and imprisoned. Humiliated and dreading what horrific torture she’ll endure, she asks to be put to death. To her surprise, rather than tearing her limb from limb, the tribe leader asks for her hand…in marriage! Will Serafina face a cruel and abusive arranged marriage? Or will she discover that these tribes aren’t as barbaric as she was led to believe?
