Chen Rong woke up drunk, the silky feeling on her hands made her stunned for a moment, and in a split second, a pair of soft and boneless hands wrapped around her waist.
“A Rong, you are not allowed to look at others in the future, otherwise, I will be angry.”
The system is roaring: “I told you to stop her from blackening! I didn’t let you sleep with her!!!”
Chen Rong: “???”

- Description from novelbuddy

Klein’s greatest wish is to transmigrate to another world and live life in an isekai, just like in anime, manga and novels. However, fate is on his side and the typical truck that the main characters always carry in isekai runs over Klein. But, to his bad luck, he lived a few more days in the hospital and, just on the day he died, Klein heard a ⟨⟨-DING-⟩⟩ that he knew it meant. That was the day of his death, but also the beginning of his adventure into another world.

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.

streak of being publicly humiliated in every story route. In other words, he was the designated cuck of the game Academy of Roses.Too bad for everyone, Cassius is now possessed by Arawn—a burned-out gamer who just tried to kill himself after exacting savage revenge on his sister’s cheating husband.Waking up in the body of the most pitiful character in eroge history? Not ideal. Finding out his missing sister has also been isekai’d and is now pretending to be Cassius’s noble “sister” to avoid suspicion? Wild. Realizing she’s about to be married off in another forced engagement plot? Yeah, fuck no.Armed with system powers(everyone has it), broken stats(for your average joe), and a big 'sister complex'(Not Incest) on steroids, Arawn has one simple plan: Live a peaceful life with his sister, for it he would, Break the rules. Shatter the narrative. And if anyone tries to play the protagonist? Use them for his own plans.This time, the cuck’s got teeth. And he bites back—in the most painful ways.—————Warning: The MC is a villainous character, he is psychotic, manipulating, borderline insane and unhinged. So, please keep that in mind
