In June 1582, Nobunaga was attacked and forced to commit seppuku in Honnō-ji in Kyoto by the army of Akechi Mitsuhide. Yasuke was there at the time and helped fight the Akechi forces. Immediately after Nobunaga's death, Yasuke went to join Nobunaga's heir Oda Nobutada who was trying to rally the Oda forces at Nijō Castle. Yasuke fought alongside the Nobutada forces but was eventually captured. When Yasuke was presented to Akechi, the warlord allegedly said that the black man was an animal as well as not Japanese and should thus not be killed, but taken to the Christian church in Kyoto, the "Nanbanji" (南蛮寺). However, there is some doubt regarding the credibility of this fate. There is no further written information about him after this.
