You Think Reincarnation Alone Can Let You Get Away, Big Brother?

[Yandere]

"The younger sister who once imprisoned me is lurking somewhere in this world──

After graduating from high school, I was held captive by my younger sister for five whole years. I finally managed to escape after countless hardships, only to be run over by a truck and reincarnated in another world. At last, I was free of my demon-like sister...

In this brand-new world of freedom, my name is Jack. As the only son of a noble family, I should have been starting a happy new life, surrounded by my loving parents and thoughtful maid, Aneli.

That's right, the younger sister who died alongside me was reincarnated in this world too. With a new name and appearance, she could be lurking anywhere right now. But this time, I have power granted to me by a god, among the strongest in the world. This time, I'll use that power to drive her off and protect my happiness and the people around me──!"
