A different text, the Kaijo Monogatari (dated to 1666) differs considerably from the Nitenki version. In it, Gonnosuke is a boastful and brash warrior who duels Musashi intending to see how Musashi compares with Musashi's father in swordsmanship. The fight occurs in Akashi, not Edo, and Gonnosuke wields a staff four shaku in length and reinforced with steel rings. After his defeat, he then went to Mount Homan-zan in Chikuzen (near Fukuoka), where he practiced considerably, changing his preferred weapon to four shaku and two sun in length - 1.27 meter as compared to 1.21 meter. This school was called the Shinto Muso-ryu because of Gonnosuke's previous training under Sakurai Osuminokami Yoshikatsu of the Shinto-Ryu. The school he founded to transmit his techniques has some old records which claims that Gonnosuke, struck by his defeat, went into solitary meditation until he received divine inspiration in a dream; he then invented techniques to fight against Musashi's two swords using only a stick, and defeated Musashi on their next encounter. Assuming the records are accurate and genuine, this would be the only time Musashi was defeated, as the vast majority of documentation states that Musashi was never defeated.
