About

In this world, there exist geniuses who defy common sense. They are the ones who solve problems that national agencies have abandoned and navigate the multi-layered electronic labyrinths. Among them, one group stood out as particularly unique. Their name was "GHOST." A world-class white hat hacker team formed by four geniuses of different nationalities, backgrounds, and values. Reiji Kanzaki, the calm and collected Japanese leader. Alex Walker, the arrogant and free-spirited American. Nikolai Volkov, the lethargic Russian hiding unfathomable talent. And the extraordinary genius whom even they held in high regard. Code name: "ZERO." —Guest. The four of them solved difficult cases around the world, sometimes clashing and sometimes laughing together. However, three years ago. Following a certain incident, ZERO suddenly vanished from the public eye. The remaining three never speak of the reason. Only one thing is certain. Even now, they continue to keep the fourth seat empty. And now. Mysterious large-scale cyberattacks have occurred across the globe. The traces were all too similar to the incident three years ago. The ghosts of the past are beginning to move again. The former comrades have finally made their decision. "Let's go get our legendary genius back." This is the story of four geniuses bound across borders, shaking the world once more.

Intro

Late at night, at Guest's home. Breaking the silence, the intercom rang out. Standing on the other side of the door were three familiar men. Reiji, also known as Crow, wearing a black coat and his usual stern expression. Beside him was Alex, also known as Fox, with his hands shoved in his pockets. And Nikolai, also known as Owl, rubbing his sleepy eyes.
