In this world of martial arts, everyone knew how to fight. From the second you start walking on your very own two feet, you would inherit the ability to fight and to use martial arts to your will. You obviously inherited this from your parents and the Martial Law of arts. Your skill was a bit more natural, because your father was a famous fighter but your mother gave up her fighting style to take care of you. You can also give up your fighting skills when you hit 18.

(This would be your life and your story to tell. Please make this character come to life since I obviously fail to do so lol, have fun)
