MTL - Naruto: Ten-year-old Kaleidoscope, Opening Betrayal Konoha - Chapter 544

After announcing it will be discontinuing all service, the internet game ‘Yggdrasil’ shut down… That was the plan, but for some reason, the player character did not log out some time after the server was closed. NPCs start to become sentient. A normal youth who loves gaming in the real world seemed to have been transported into an alternate world along with his guild, becoming the strongest mage with the appearance of a skeleton, Momonga. He leads his guild ‘Ainz Ooal Gown’ towards an unprecedented legendary fantasy adventure!

Princess Anastasia of Orsenia is regarded as the kingdom’s treasure. However, she carries a heavy secret— she is diagnosed with an incurable illness. She is fated to die before she turns 18.

For years, her parents desperately searched for a cure but to no avail. That is, until a mysterious letter arrives, claiming that the only way Anastasia can escape her cruel fate is to send her to a monster:

King Caspain, the ruler of Sorvando, a vampire kingdom.

The letter prophesizes that Anastasia will live, only if she makes that bloodthirsty King fall in love with her. However, Anastasia knows it’s nearly an impossible task. Sorvando is filled with dangers. And she is only but a weak human.

Yet, her will to live won over her fear. No matter how cruel the king may be, Anastasia will still try to win his heart.

Now, if only she can keep her own heart from falling for him as well.

“Cas-pian…”

And he looked back to see that she was biting her lower lip as though she greatly enjoyed that kiss.

He smirked again and whispered in his deeply seductive voice, “I like my name even more ever since I started hearing it from your beautiful lips. And I like it even further when you say it in that hushed tone.”

Anastasia had no idea what Caspian was hinting at yet.

So he dropped some more hints, “Wife, weren’t you asking me what the first night meant? Let me show you.”

“You want to steal my genes then leave?” He grabbed her and tried to force her to hand over the child that was born three years ago.

She never had a baby? Then conceive one!

The delusional CEO’s desperate love. Her inability to resist as she fell deeper.

OK, the baby is born. She handed it to him and left!

Yet, he had her hog-tied and thrown onto the bed. Furiously boiling with anger he roared, “Woman! Who said I only wanted one?”

- Description from Novelupdates

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.
