Sonyeo*Guwondaehaeng

Synopsis

This world has been destroyed. All because of Won Jeong-Hyun, the world’s number one. He is humanity’s greatest hero and its worst traitor …Or so I thought? *“…If only the last person standing hadn’t been you.”* He saved me just before the world ended, then died. And to stop the conspiracy, I suddenly found myself sent back in time! As the youngest S-rank Hunter at the age of 8! Alright then, I’ll fulfill Won Jeong-Hyun’s wish in his place. Starting today, I’m taking over the mission to save the world! (Source: Naver, translated)
