The Right of Sorry for Killing You

The Right of Sorry for Killing You was a Taiyounese custom that allowed for adventurers to cut down commoners for the slightest perceived disrespect. Adventurers were only allowed one slam, which helped cultivate Taiyounese martial arts into its modern form of running around and charging up a single hissatsu waza move. While Taiyounese style martial arts was not adopted by the rest of the world, The Right of Sorry for Killing You was accepted into global society. However, over time commoners became an extinct class and the only class left were the adventurers. The social pyramid of who could slam who became blurred and The Right of Sorry for Killing You subsequently became a universal right. Henceforth, The Right of Sorry for Killing You became known as Universal Basic Killing (UBK).
