Hanma Baki (named "Wild Fang" by his father) is a boy born under an unlucky star. Since the day of his birth, Baki has been rigorously training at all kinds of martial arts, strengthening himself at his father's command. For he must obey his father's rule that at his "coming of age" Baki surpass his own father, Hanma Yuujiro, "the most powerful creature walking on earth." Baki's life has been nothing but trouble. This has given Baki a wild nature and convinced him that "to be the most powerful" is his way of life. Tenacious and fearless under all adverse conditions, Baki continues his training looking for new masters and new challenges to strengthen his personality and become "the strongest man on earth." That road is a lonely one and Baki experienced the cruelty of his sick dad in a move that would change his life forever.
