Asano Naganori
In 1694, Yasubee came to the aid of his dōjō mate and pledged uncle in a duel at Takadanobaba in Edo, killing three opponents. He received acclaim for his role, and Horibe Yahei of the Akō Domain asked Yasubee to marry his daughter and become the heir to Yahei's family. Yahei was so impressed with Yasubee that he pleaded to his liege, Asano Naganori, to allow Yasubee to keep his Nakayama surname while marrying into the Horibe family. Yasubee eventually took on the Horibe surname and became a successful retainer of the Akō Domain.
