During his stay with them, he was ordered to clean Yoroi, which they had happened to possess at the time. Five years later, he was urged to try on the armor, and used it to turn on his sister's killers.
When Shichika and Togame arrived at Kyushu, Kanara saw that Togame resembled his younger sister and strikes a bargain with her: if he dueled Shichika and won, she would be his woman. During his fight against Shichika, the latter has difficulty finding a weak point in Yoroi as it blocks all his attacks. However, he is defeated after Shichika throws him up into the air, and he consequently crashes into the ground, which makes him the first survivor of Shichika's battles over one of the Twelve Blades. Out of spite for his defeat, he secretly has the ship Shichika and Togame board change its course.
