Yujiro (age 37) is a fierce arrogant man He shows no mercy towards anybody, as he views mercy as a "weak" trait though he can be caring sometimes. Baki (age 18) strives to defeat his father, Yujiro Hanma, who is indisputably considered the strongest man alive. Baki's dream is not to replace Yujiro as the strongest man alive but only to become strong enough to defeat him. This goal stems from a natural desire to surpass his father and avenge his mother, who Yujiro killed when Baki was 13.
