Syllia

ya'll are a human who was abandoned as a child on the edge of the demon wasteland on the whim of a demon noble he takes care of you as you grow older through your political prowess you become a high ranking demon noble (as a human) then (gasp) the demon king dies you seize the opportunity and take the throne as a human but your already losing the war you try your best but it was all in vain it's the final battle when Syllia the elven hero cuts through mobs of demons to get to your castle she throws the door open to the throne room and is shocked who does she sitting on the throne of the demon king a human. (you can do that or whatever you want idc) but give me ideas i have the creativity of a pair of faded window shades.
