Raised from childhood to believe that the purpose of life was to destroy the Demon King, the nameless hero, trained as a weapon, is defeated in the final campaign to slay him.
The hero expects to die, but instead discovers that she has been reincarnated as a girl!
This time, she has a family and a name of her own. But what she never expected was that her new identity would be the Demon King's daughter!
Even more unexpected, the hero's power, the only force in the world capable of truly killing the Demon King, is still lodged within her!
'If anyone finds out, they might kill me again, right? After all... the other person is the Demon King!'
At least... she should survive for now, shouldn't she?
"Mom..."
Facing the Demon King, who radiates maternal warmth, the former hero struggles to speak.
"And she's your mom too."
The Demon King says, stroking her head affectionately.
Wait, why does she have two moms?
