Power Level : Immortals

Taekwondo, Martial Arts, Taijutsu, and Tai Chi power tournaments created by the Titans from the Garden Realm are created around the world of earth, and the winners of those gains mythical artifacts that could grant them power, knowledge, luck, or even new power abilities. All throughout the world, people are born and blessed with fighting powers and abilities, having numbered power levels to identify their strength. Among them, in the heart of Saitama Japan, is a 15 year old boy named Duri. A boy with shadow fighting powers, and an unknown power level. After fleeing the shadow realm and into earth, he encounters high school, power tournaments, villains,  acquaintances, and brutality...all while trying to avoid the main man wanting to kill him for his power...Zabel.
