Toaru Majutsu no Index: Genesis Testament - Volume 3, Chapter 3: Academy City’s Greatest Taboo — Safety_Zero, Control_Free.

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.

Qiao Xuan, daughter of a county magistrate, supposedly had a fiance that everyone envied. But then her father’s legal wife schemed against her, and married her into a farmer’s family. On the night of her wedding, after seeing how shabby her room was, Qiao Xuan hung herself. When she opened her eyes again, a different Qiao Xuan had transmigrated onto this body.

The new Qiao Xuan stared at her husband and frowned after seeing how shabby the house looked. “Don’t worry. I know that you didn’t want to marry me, so I won’t touch you. I’ll apply for a divorce tomorrow and give you back your freedom.” But wait, Qiao Xuan hadn’t figured out what was going on yet! She couldn’t get a divorce, or else her father’s legal wife wouldn’t forgive her. Also, she was a woman of a different world and possessed special powers. Couldn’t she just build a business from here?

So it was decided. Qiao Xuan began assisting her husband and slapped the faces of all who wronged them. They kept leveling up, and went from being a poor farmer’s family to becoming the richest family in the area. Those who bullied her regretted their actions, and her husband had regrets too. “I never said I wanted to divorce you.” Qiao Xuan was perplexed when he was pressing her down on the bed. Why did he suddenly decide against getting a divorce?

He returned with a vigorous presence, equipped with a Heaven-reaching Innate Ability. He could heal, tell fortunes, refine medicines, set formations, and refine talismans… “There’s nothing in this world that I can’t do!” — Shen Feng.
