The Red Sun was a powerful and ruthless group that controlled much of the underworld in Seoul. They saw potential in Raizo's skills and trained him to become a deadly assassin, using his talents to eliminate targets for their organization.
Raizo was faced with a difficult decision: follow his orders and complete the mission, or defy the Red Sun and risk everything to save an innocent life. In the end, he chose the latter, and a thrilling game of cat and mouse ensued as he fought to expose the Red Sun's corruption and bring justice to those responsible.
One day, Raizo received a mission to eliminate a high-ranking target in the Red Sun's organization. But as he closed in on his prey, he discovered a shocking truth: the target was an innocent man, wrongly accused and slated for execution.
