Yaiba Manga, Volume 1.

YAIBA was the second ongoing manga series created by Gosho Aoyama. It ran from 1988 to 1993 in Shonen Sunday and later had an anime known as Kenyu Densetsu Yaiba (剣勇伝説YAIBA Ken'yū Densetsu Yaiba?, "Legend of the Swordmaster Yaiba") that ran from April 9, 1993 to April 1, 1994. The manga was collected into 24 volumes originally and released three more times after that: the wide version (12 volumes), the paperback version (10 volumes), and re-release version (24 volumes). A video game for the Super Famicom, as well as a game for the Nintendo Game Boy, were also both released.

The story was about a young samurai and his adventures in modern day Japan. There have been numerous references to it in Detective Conan.

Plot summary

In order to train his first son, Yaiba Kurogane, to be a great samurai, Kenjuro Kurogane raises him in the African wilderness. But during training one day, they (along with their new pet tiger Kagetora) are caught in a box of pineapples about to be shipped to Japan. At the Tokyo airport, Kenjuro runs into his old kendo rival Raizo Mine and his daughter, Sayaka. Kenjuro leaves Yaiba with Raizo and Sayaka (despite their protestations) and heads off on a journey.

Meanwhile, Yaiba makes instant enemies with Sayaka's school's kendo star, Takeshi Onimaru. After losing in a duel to Yaiba, Onimaru begins training with his family's Fuujin-ken (Wind God Sword) and becomes possessed and starts to take over Japan. To combat this, Yaiba seeks out the Raijin-ken (Lightning God Sword) and is trained by the legendary samurai Musashi Miyamoto. Onimaru sends wave after wave of minions after Yaiba and his friends, leading to a final showdown at his flying castle.

In Part 2 of the story, Yaiba's use of the sacred Dragon Orbs to help defeat Onimaru reawakens the evil princess of the Rabbit People, Kaguya. Kaguya seeks out the youth of all of the women of the world for herself. Ultimately, Yaiba has to join forces with Onimaru to defeat Kaguya and her strongest minion Gekko.
