President Wife is Pretty and Cool - Chapter 547 - Children Aren't Easy to Deceive   

Hikaru crossed to Misty World with billions of other players. This world is full of monsters and fog.

Hikaru thought he wouldn't be able to survive in this horrible world when he suddenly possessed an SSS-class skill.

[Ding! Maximum Evolution.]

[Ding! Do you want to evolve Succubus into Fallen Angel?]

[Ding! Do you want to evolve Komodo into the Darkness Dragon King?]

[Ding! Do you want to evolve the Wooden Sword into a God Sword?]

Hikaru: “In this world, I am the lord.”

By the time I realized it, I had reincarnated into another world.

I kept sleeping, and at some point I became a Demon Lord.

Even though I never wished for it.

But for me to not have to work, this world is the best. It must be true that good things happen to good people.

The flavor of Sloth is as sweet as honey. Glory, diligence, virtue, or honor. I have no interest in anything like that.

What’s there to hide? The Lazy king is… none other than me.

The world dare to ask, what is God of War?

“It is with the flesh dominates the world, fists burst into the starry sky, palms crack the sky, destroy all the way, push the eight wastes and Liuhe horizontally!”

“It is with a brave heart, passing by the bustling, swallowing loneliness, fearless and invincible, eternal immobility alone!”

For both, for… God of War!

This is a young man with a mysterious life experience. In order to obsessively in his heart, he crossed the heavens and the world, traveled all over the world, with a pair of bare-handed stories that tear thousands of legends… The rise of the God of War, all the way!

- Description from MTL

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.
