Damn, I Have to Marry the Strongest Antagonist at the Start? - Chapter 546 - 542-Friend? Or Foe?

“Oh Lord Lunareio, you are the only one who can save our world.”...My name is Rikuya Takatsuki, and I didn’t ask to be summoned to some fantasy world with my classmates. But there I was, expected to be a hero and protect the Kingdom from Realm Eaters, dimensional monsters chewing through reality.Apparently, all the races summoned forth heroes of legend, which was sort of a shocker to me since it wasn’t the cliché “slay the demon king” trope.Sounds cool, right? Wrong. While everyone else got flashy powers and legendary classes, I was slapped with the FFF Auto Hero class—no skills, no perks, and no respect.The kingdom handed me some pocket change and politely told me to scram.Fine by me. I was all set on enjoying the easy life in this new world anyways, when out of nowhere a bunch of cultists kidnapped me, claiming I’m their prophesied god or whatever.They gave me a mansion, unlimited snacks, and zero responsibilities, so of course, I played along.But then my so-called useless class kicked in. Turns out Auto Hero means my body hijacks itself whenever there’s danger, turning me into some kind of unstoppable killing machine. Efficient? Sure. Ethical? Not so much. Now everyone thinks I’m this terrifying cult leader who takes down monsters, corrupt kings, and anyone dumb enough to stand in my way.While my classmates enjoy their shiny hero lives, I’m here in the shadows, leading a cult, toppling kingdoms, and pretending I have some grand plan. The truth? I’m just winging it.I mean... what’s the worst that could happen?

There was a mysterious old man who approached the failed swordsman with the “100 million years button”. A magic button which can achieve the same effect as training for 100 million years if you push it.

The failed swordsman who pushed the button had his doubts, but immediately felt tremendous power rising in his body. So he pushed the button many times.

However it was a cursed button. The moment it was pushed, he was confined to the 100 million years prison of time. The first 100 years were devoted solely to training. After 1000 years he had forgotten why he swung his sword. He stopped thinking completely after 10,000 years had passed. After 100 million years he became crippled and finally managed to return to the real world. At the same time losing all his memories from the past 100 million years, the only thing that remained were his sword techniques. “I can become stronger just by pressing the button!” or so he thought and pushed the button many times after that. Foolishly trapping himself in that 100 million years of hell each time.

As he continued this loop, he began to think “If I destroy this world, will I get out of here?” A few billion years later, he finally escaped from the loop.

This is the story of a failed swordsman trying to make a name for himself in the world.

Lady Bertia, who’s become my fiancée, is a bit odd. On our first meeting, she proclaimed herself a villainess noble girl who’s been reincarnated and said that she’s working hard every day to become a splendid flower of evil that’s elegantly put in her place.

I don’t get it.

But she entertains me because I don’t understand.

That’s why I think I’ll observe her for a while.

This is a story of a crown prince who’s so talented and handsome that he’s grown bored of his easy-mode life. A story of this prince observing a self-proclaimed villainess noble girl (who seems perfect at first but is a bit off) who’s become his fiancée as she snatches flags and breaks them into pieces.

There are a total of seven sins, and a revelation is made to a young man named Alex that he is destined to become a demon lord, more especially a demon lord of sin called LUST.

It's not like he can change that and because he always knew something about himself was different—not in a physical sense, well, maybe a little—and not in a mental sense—but rather because he is thrown into a demonic war that compels him to accept his new reality.

He was only aware of a difference in himself. Relating to him and the ladies who are drawn to him... Well, it was more or less like he was a magnet in front of all the girls, and all the girls were drawn to him like a metal.
