しがない中年社畜だった主人公は、やり込んだ18禁ゲームの世界に転生し、誰からも嫌われる悪役第五王子エスメラルダとして生きることになる。前世では他人のために生きてきた彼は、今世こそ悪役の立場を利用して自分の欲望のままに生きると決意する。しかし、嫌われるように振る舞っているはずなのに、なぜか胸の大きな美少女たちに惚れられてしまう。欲望のままに「悪のおっぱい王国」を築こうとする、勘違いハーレムファンタジー。
A middle-aged corporate wage slave is reincarnated into the world of an adult game he played extensively, becoming Esmeralda, the fifth prince who is hated by everyone. Having spent his previous life living for others, he resolves to exploit his villainous status and live according to his own desires. However, despite trying to act like someone everyone should hate, he somehow wins the affection of beautiful, busty girls. Thus begins a comedic harem fantasy about building an “evil kingdom of breasts” while pursuing his own desires.
