ざまぁ確定の悪役貴族に転生した俺が、最推しのラスボスヒロインと結婚することになったので原作知識をフル活用して幸せになります～なお、嫁を馬鹿にした勇者は俺の敵じゃありません～

“Ike-sama, could you please help me?”

Yuto Satou, an overworked employee at a black company, got reincarnated as Ike Hanbulg, the villainous duke son in an otome game Fortune Lover, who was despised for being fat, vile and weak.

“Females like you should just shut up and offer their breasts to me…!”

With such disgusting final words, Ike was defeated by the hero’s party in every heroine’s route. That kind of future… It was just too awful! Moreover, Ika had a fiancée. Her name was Luna Olhein. She was the character that almost brought the world into destruction in Fortune Lover. She was the final boss that the hero had to defeat.

Luna had an incredibly tragic fate. Due to the prophecy that said she would be the one to destroy the world, she was persecuted by her own parents and by everyone in the world.

Luna could only watch as the hero and the captured heroine smiled together as they achieved their happy ending. In other words, Luna was the stepping stone for the hero and the heroine.

And now, the said Luna was standing before me as my fiancée.

However, please don’t misunderstand. Luna is my favorite character. She’s a beautiful girl that’s exactly my type. If I could have the chance to make her happy, I absolutely would make her happy with all of my might. And so, to achieve that, I had to…

1. Obtain the strongest hidden weapon in this world, the Staff of Dragon Star

2. Defeat the hero of the original game who dared to underestimate me

However, just escaping from my life as a mob wouldn’t be enough. I needed to start special magic training in order to prepare for the upcoming crisis.

“Ike, unfortunately, there’s nothing more I can teach you. I mean, what can I possibly teach you when you’re already stronger than me?!”

After saying those words, my instructor threw in the towel… Nonetheless, I kept on putting all of my effort in training until eventually, my father said..

“I believe it’s about time I entrust the Hanbulg Duchy to you.”

“Understood! I shall accept this honor with a joyous heart!”

I was appointed as the head of the duchy.

“Ike-sama, I adore you so much~♡”

And so, I managed to change our future, which was supposed to end in a bad ending. I managed to secure a happy married life with Luna.

Ah, farewell, my mob life~

However, the original hero, who was defeated by me, harbored resentment toward me and Luna. He became obsessed. He stopped at nothing to bring us down, but he always failed at every turn until eventually, he ended up dyeing his own hands with evil…
