Yamauchi Taka

Yamauchi Taka was a Japanese monk and member of the Assassin Order during the Sengoku period of Japan. He was an affiliate of Hattori Hanzō, an Assassin working for Tokugawa Ieyasu.

In June 1582, Taka made contact with Chaya Shirojiro Kiyonobu to retrieve information on a mission he was assigned to by Hanzō. Knowing that Oda Nobunaga would soon be attacked by his vassal Akechi Mitsuhide, Kiyonobu revealed that Taka was to retrieve Nobunaga's Sword of Eden before it fell into enemy hands. On 21 June, during Mitsuhide's attack on Honnō-ji temple, Taka killed Nobunaga and brought the Sword to the Assassin Liu Yan to transport it away from Japan.

Taka later participated in the Battle of Sekigahara on 21 October 1600 on the side of the Tokugawa, fighting alongside Ii Naomasa. After Naomasa was critically wounded by a rifle unit under Shima Sakon's command, Taka assassinated Sakon to exact revenge and ensure victory for the Tokugawa.
