Zoro was a doujouyaburi, collecting dojo signboards. Kuina the daughter of a dojo master accepts Zoro's challenge. Bow to the gods, bow to your opponent, begin! Smack, smack with just two shinai strikes Kuina sends Zoro flying to the ground. Zoro gets up and strike a great "two sword/shinai technique" pose. Zoro charges towards Kuina, smack one hit right in between the eye, Ipon! Zoro have loss. Zoro joins the dojo and swears that he'll beat Kuina one day. Thus begins his training, Zoro gets stronger by the day but still can't beat Kuina. On the 2001st challenge they used real Katanas, during the fight she commented that Zoro lacks the stamina to carry two swords. Kuina is still undefeated. After the fight she consoles Zoro, as they grow older Zoro will eventually surpass her. A woman can never be the world's greatest swordsman.
