Neon Sutra of Vengeance

In the rain-slicked alleys of Shin-Yoshiwara, a district where digital wealth disguises ancient greed, a massive investment fraud shatters countless lives. When the judicial system fails the victims, a quiet accountant named Ren chooses a path of calculated annihilation. Adopting the mantle of a ruthless avenger, he systematically hunts the architects of the scheme, only to discover that the knife of revenge has two edges. As he delivers his final verdict, the neon glow of the city reflects not in the eyes of a savior, but in those of a new predator.
