Zettai Miryou de Isekai Kouryaku! Kouman Onna Wakarase Harem Keikaku

"I wish I could make all those girls who look down on me do whatever I want..."

While indulging in these daydreams, Haruma is suddenly summoned to another world by a succubus. He lands in a nation ruled by extreme female supremacy, where a fierce war for the queen's throne is rapidly escalating. Thrown straight into the middle of a battlefield, Haruma finds himself in a life-or-death crisis almost immediately. However, he is saved in the nick of time by Alicia—one of the claimants to the throne—who brings him back to her mansion. His relief is short-lived, though, as the shadow of an assassin creeps up on his savior. To help Alicia, who dreams of true gender equality, ascend the throne, Haruma resolves to use a forbidden power to charm these arrogant women and bend them to his will.
