"Dahna: Megami Tanjou" is a Sega Genesis game centered on sisters Dahna and Regine from a affluent family with a unique magical ability to summon elements. Their magic is coveted, especially Regine's strengthening powers. Following their parents' murder on Dahna's seventh birthday, the sisters were separated. Dahna took refuge in a village and trained her magic and combat with village sorcerer Magh. A decade later, an attack led by a malevolent sorceress kidnaps Magh, leading Dahna to her initial battle.
There lived a wealthy family whose heirs were two daughters: Regine and Dahna. These two sisters were born with a strange magic that could enable them to summon the elements and other impossible things; it was this magic that many within the spiritual underworld lusted after, particularly Regine whose powers grew stronger with age. On Dahna's seventh birthday, the sisters' parents were murdered in a violent kidnapping attempt, but the wreckage separated the sisters and Dahna escaped.
Dahna hid in secrecy, but eventually took shelter in a nearby village where she honed her magic and combat abilities under the guidance of the village sorcerer Magh. Ten years later, a mysterious invasion force led by an evil sorceress attacked her village and kidnapped Magh, prompting Dahna on her first battle.
