"At the time, Takeda was in the middle of a war with Oda and Tokugawa. If people learned about his death at a time like that, it'd probably have had a bad impact on the war. 'Cause of that, he left a will sayin' that his death should be kept hidden for three years. ...Hideyoshi did the same thing, right? He totally suppressed information about the death of his master, Oda Nobunaga, so that the enemy wouldn't find out, quickly made peace with Mouri, and defeated Akechi in the Battle of Yamazaki."
