Ikkitousen

The ikkitousen( 一騎当千, Lit. "Matchless Warrior") is the name given to the proven strongest warrior in the world. It is the title that was given to those whom exterminated their opponents after engaging in The Tenkaichi Budoukai event. The only way to become The Ikkitosen is to enter and utterly obliterate every last opponent and enemy martial artist in The Tenkaichi Budoukai, proving ones place as the supreme master of combat in the process.. Only a select few have ever managed to obtain the title for themselves. In doing so, they prove themselves the ultimate warrior with no equal.

History
The title of "Ikkitousen" was created by the powerful gods who served as the ancestral forefathers of the 12 imperial families. During the time of the original Tenkaichi Budoukai, before it was transformed into a mere consumer and tourist attraction, the strongest and most talented fighters from the 12 bloodlines would gather at Jigoku Island, and brutally challenge eachother in mortal combat. The fighter that stood as the last man standing would prove his family as the strongest of the 12, and cement the god in which they descended from as the mightiest of the 12 ancestors, obtaining rights to the title, "Ikkitousen". However, after the destruction of The Kamage Clan, and the transformation of the Tenkaichi Budoukai into an annual tourist attraction, the title of The Ikkitousen was permanently branded to a member of The Daidoji Clan.
