Transmigrate as Uchiha Madara and Rise to the Top

(Heroes + witches + magical girls + monsters + multiple heroines + world-hopping. World unlocked: the shinobi world. Another world will be added each day from now on, and the synopsis may change.) After dying, she is reborn in a new world full of heroes and monsters. What are the seemingly righteous heroes really like in private? Are monsters truly as evil as the news claims? That night, she witnessed a hero’s wickedness and swore to take revenge on the hypocritical hero. As an ordinary person who couldn’t even fight back against a chicken, how could she ever get her revenge? But when she turned eighteen, her fortunes changed. Standing at a crossroads of fate, he was given two choices: live an ordinary life or descend into darkness. Thinking of her parents’ brutal deaths and their killer’s dazzling public image, she chose to abandon everything and descend into darkness in exchange for the power to get revenge. The power of Nyx descended upon her, and the long-delayed System opened the gates to other worlds. What is darkness? What is despair? What is light, and what is hope?
