Death battle with Miyamoto Musashi
Arima Kihei was killed in 1596, just ouside the village Hirafuku in the province of Banshu by Miyamoto Musashi, who was thirteen then.
"I have trained in the way of strategy since my youth, and at the age of thirteen I fought a duel for the first time. My opponent was called Arima Kihei, a sword adept of the Shinto ry?, and I defeated him. "
Musashi states that his first successful duel was at the age of thirteen, against a samurai named Arima Kihei who fought using the Kashima Shint?-ry? style, founded by Tsukahara Bokuden (b. 1489, d. 1571). The main source of the duel is the Hyoho senshi denki ("Anecdotes about the Deceased Master"). Summarized, its account goes as follows:
In 1596, Musashi was 13, and Arima Kihei, who was traveling to hone his art, posted a public challenge in Hirafuku-mura. Musashi wrote his name on the challenge. A messenger came to Dorin's temple, where Musashi was staying, to inform Musashi that his duel had been accepted by Kihei. Dorin, Musashi's uncle, was shocked by this, and tried to beg off the duel in Musashi's name, based on his nephew's age. Kihei was adamant that the only way his honor could be cleared was if Musashi apologized to him when the duel was scheduled. So when the time set for the duel arrived, Dorin began apologizing for Musashi, who merely charged at Kihei with a six-foot quarterstaff, shouting a challenge to Kihei. Kihei attacked with a wakizashi, but Musashi threw Kihei on the floor, and while Kihei tried to get up, Musashi struck Arima between the eyes and then beat him to death. Arima was said to have been arrogant, overly eager to fight, and not a terribly talented swordsman.
