I Reincarnated as the Mob Villain Prince Who Dies Before the Game Starts After Pouring Excessive Effort into Perfecting the Weakest Magic [Dark Blade] to Find Happiness with My Favorite Heroine Younger Sister, It Turned into a Ridiculously Overpowered Skill
by こはるんるん
I, Luke, the fifth prince of the Celestia Empire, had a younger sister who was one year my junior. She’s my unbelievably cute younger sister Diana, who loves me dearly, but in truth, she’s fated to die after turning to darkness.
This is the world of the RPG “Chris Knights” that I played in my previous life, and Diana ends up becoming a demon lord who is killed by the protagonist.
My beloved younger sister, destined to die at the brink of despair?
I can’t allow such a future.
Ever since I was a baby, I’ve worked hard to resist that fate.
She only turned to darkness because our mother was assassinated and our father, the emperor, used her as a tool of war.
I’m going to completely destroy that kind of game scenario.
This is the story of a mob prince who strives to become the strongest in order to protect his sister from falling into darkness.
