After I Transferred Schools, My Ex-Girlfriend Became the School's Top Dog

[Underworld] [Not invincible, not brainless, no harem] [Capable of every evil] That year, I scraped by like a stray dog. Then I rose like a dragon bursting from the sea. Who would dare stand in my way? That year, I was beaten at school until I cried for my parents. That year, I wielded an AK-47 and killed my way through the school, oblivious to heaven and earth! Only those willing to risk everything, daring to drag the King of Hell from his throne, can become kings! From school to society, from our country to foreign lands, every fight was for the justice I believed in! There is only one word between a gentleman and a villain: virtue. There is only one word between a hero and a ruthless strongman: honor! This is the story of an ordinary student who rises step by step to become the king of the underworld.
