The Silent Vengeance

In the fictional East Asian nation of Shinwa, a young programmer named Yuki Takahashi is falsely implicated in a major drug smuggling case, "State vs. Akihiro Sato," after unwittingly receiving a suspicious package. An online witch hunt erupts, and relentless cyberbullying drives him to leap from a rooftop. Five years later, his sister Miyu, now a brilliant cybersecurity engineer, meticulously tracks down every person who posted hateful comments. Using her skills, she engineers a series of devastating, untraceable "accidents" to deliver a chilling, personal retribution. As a journalist and a guilty former commenter begin to connect the dots, they are drawn into a high-stakes game of cat and mouse that questions the very limits of justice. When the past resurfaces with the real drug trafficker, Miyu must decide whether to become a monster or redefine redemption, proving that the line of justice is often drawn by those who dare to break the rules.
