But when she opened her eyes, she discovered, to her very horror, that she had returned twelve years into the past…

Ben was having the worst day of his life—then he died. But instead of moving on to whatever comes next, he woke up in the Wizarding World as Benedict Brown, the alternate male version of Lavender Brown. Which is... concerning, because Lavender Brown did not have a great time during the Second Wizarding War.On the bright side, he’s apparently the Dovahkiin. And he has a Skyrim shop system. So, you know, pros and cons.Can he survive Hogwarts, Death Eaters, and whatever else this world throws at him? Or will he end up as werewolf chow just like Lavender? One thing’s for sure—he’s going to loot everything that isn’t nailed down.

Having been reborn, she takes one glance at her ridiculously handsome husband and wonders if she had suffered from brain damage back then—she had actually demanded for a divorce with him. Repeatedly!

After getting shot, Lucas, a serial killer, reincarnated into the novel world as a tragic villain with the same name, Lucas Ciffer.

Lucas Ciffer was supposed to be the Holy Kingdom's successor to the throne, but his demonic appearance and the powers he possessed terrified the entire kingdom. A white-haired boy with red eyes and pale skin, together with his dark powers, got persecuted and exiled by his own family. Not to mention that in the future he was destined to die by the hand of the hero.

Lucas fell from holiness, and, with the serial killer's bloodlust and knowledge of the future, he decided to prove the world right.

Yes. I could be a villain; no, in fact, I WILL BE THE VILLAIN.
