Ahn Soo-ho, the greatest prosecutor in the world and a civil servant of the Korean Hunters Association. He became a public servant to end the Gate, but was betrayed by his colleagues when one of the so-called final gates, the disastrous gates, was conquered. Why did his colleagues betray him? Because their power would disappear when the Gate ended. Is this the end? When Soo-ho's consciousness began to fade! [Ahn Soo-ho's player system reboots.] The system gave Soo-ho one more chance. A chance to go back to the past and set everything right. (Source: Kakao Entertainment, translated)
