Description
Jūbei Mitsuyoshi Yagyū is a recurring character in the manga and anime series Yaiba. He is directly based on the famous and romanticized historical samurai of the same name from Japan's early Edo period. Within the world of Yaiba, he is a legendary swordsman revived in the present day.
In terms of background, Jūbei is a master of the Yagyū Shinkage-ryū sword-fighting style. Historically, he was the son of Yagyū Munenori, the sword instructor to the Tokugawa shōguns, and studied under the famed swordsman Miyamoto Musashi, whom he continues to hold in very high regard. His physical age is complicated; while he was born in 1607, he is around four hundred years old but possesses the body of a man in his forties. He first appears when he is revived by the character Kumo-Otoko.
Jūbei's personality is dual-layered. In his normal state, he is typically calm and collected, embodying the discipline of a master samurai. He is a serious individual who does not want women to interfere with his path of the sword. However, he undergoes a dramatic transformation when he becomes intoxicated; drinking turns him into a lecherous, wild, werewolf-like figure who calls himself Yajirobe. In this state, his personality becomes the opposite of his usual composed demeanor.
His role in the story begins when he challenges another legendary swordsman, Sasaki Kojirō, to a duel in the streets of Niigata, which he wins. The protagonist, Yaiba Kurogane, then challenges him. During their fight, Musashi Miyamoto, who is now an old man and Yaiba's teacher, realizes that this Jūbei is the same student he taught centuries ago. Yaiba manages to defeat Jūbei through a trick. Overcome with shame and shock that the great Musashi no longer appears as the man he once was, Jūbei attempts to perform seppuku (ritual suicide). He is stopped from doing so by Yaiba and Sayaka Mine. After this event, Yaiba, believing Jūbei is much stronger than Musashi, asks him to become his new teacher. Jūbei then agrees and joins Yaiba's group of companions on their journey.
A key relationship for Jūbei is his deep respect for his former teacher, Musashi Miyamoto. This reverence is so profound that seeing Musashi's aged and changed form is a major emotional shock. His relationship with Yaiba begins with a formal challenge but evolves into that of a mentor and traveling companion. He also has a rivalry with Sasaki Kojirō, whom he defeats in their initial encounter.
Regarding his development, the most significant moment is his near-ritual suicide after being bested by Yaiba and his subsequent decision to live and train the young swordsman. This event marks his transition from a revived legend with a rigid sense of honor to an active participant in the new era's adventures. His abilities are formidable; he is a master swordsman considered by some to be even stronger than Musashi. He is skilled enough to defeat Sasaki Kojirō by exploiting a specific weakness in his technique. His combat prowess is the primary reason Yaiba seeks him out as a new teacher.
