Premise: Tokugawa Ietsugu; 徳川 家継 (August 8, 1709 – June 19, 1716) was the seventh shogun of the Tokugawa Dynasty, who ruled from 1713 until his death in 1716. He was the son of Tokugawa Ienobu, thus making him the grandson of Tokugawa Tsunashige, daimyo of Kofu, great-grandson of Tokugawa Iemitsu, great-great grandson of Tokugawa Hidetada, and finally the great-great-great grandson of Tokugawa Ieyasu.
Hypothesis: Tokugawa Ietsugu was considered very nice to his servants
