In Underground, Volume 1, Karim Yun, a biracial taekwondo fighter, pits his skills against New York’s most brutal underground martial artists.

Seeking revenge against the violent gang who attacked him and ended his Olympic dreams, he’s determined to battle every colorful combatant in his path.
His only obstacle is the illness brought about by the violent attack, which could kill Karim if he becomes too reckless—serving as his conscience is his nurse, who is trying to push him into changing his lifestyle but is learning more about the danger and the allure of secret mixed martial arts contests.
Created by black belt martial artist JR De Bard, this sports manga provides a detailed look into the world of underground fight clubs. Exploring fighters from various disciplines with realistic tactics and movements will thrill and educate readers.
Underground is rated OT for Older Teen, recommended for ages 16 and up for language and bloody, stylized violence.
