Saikyou Maou wa Musou shiteta noni ~Nyotaika Kaijo no Kagi wa Hitodasuke no Tabi deshita~

最強の魔王としてその名を轟かせていたディナトは
倒した女勇者アニーのアイテムに呪われ、
美少女の姿へと変えられてしまった。
しかもアニーはギャルとして復活し、
呪いのせいでディナトはアニーに逆らえない！

力の大半を失い、配下の魔物からも狙われ、
踏んだり蹴ったりな現実に膝をつくディナト。
そんな彼にアニーが告げた元の姿に戻る方法。
それは人々を脅かす魔物を倒す、
おおよそ魔王らしからぬ「人助け」の旅だった…。

Dinato, once feared as the mightiest Demon King, was cursed by an item belonging to Annie, the female hero he defeated. Transformed into the body of a beautiful girl, Dinato’s troubles only grew when Annie was revived as a gyaru—and due to the curse, Dinato is unable to defy her!

Stripped of most of his powers and now targeted by his former monstrous minions, Dinato is brought to his knees by this harsh reality. Amidst his struggles, Annie reveals the only way to return to his original form: a journey of “helping people” by defeating monsters that threaten humanity—a task utterly unbecoming of a Demon King…
