The Margrave's Daughter & the Enemy Prince(2022)

Urareta Henkyou Haku Reijou wa Ringoku no Outaishi ni Dekiaisareru

Anna, daughter of the Margrave of Halmich, is tired of the expectations placed on women in court. She has no interest in marrying a nobleman because society expects it of her. Instead, she works hard on her swordsmanship and dreams of joining her father on the battlefield someday. Unfortunately, fate deals her a heavy blow: when the hostile forces of the Kingdom of Albion invade and take the Halmich heir prisoner, she is given to the enemy prince in exchange for her brother's life.

But even in the face of these tragic circumstances, Anna still has plans of her own: "I'll infiltrate their ranks as a tribute, and then... I'll defeat the man who killed my father."
