♧A Fallen Kingdom♧ 「Sadao Mao x Reader」
『As a fallen angel who took refuge within the mighty devil's palace, you were eternally grateful for Satan Jacob, the demon king who bestowed war upon Enta Isla's four nations. Though, after that event, a hero emerged from the heavens and pledged to eliminate your hellish leader. Unbeknownst to you, because of this hero's actions, Satan Jacob had to escape to Earth, a place where human beings dwell, leaving Enta Isla to crumble down at its feet.
Well, what do you do?
Bring back your leader, that's what! And you'll go though extreme lengths to find him and bring him back. Even if it costs you your life.』
