Kenshin Uesugi is the sixteenth head of the Uesugi clan who clashed with several prominent figures of the era within his region of influence, Echigo. He is famous for being masterful in war and for his devout worship of Bishamonten, the Buddhist god of war. After his death he is known under several nicknames, which include the Avatar of Bishamonten, Dragon of Echigo, and the God of War. His rivalry with Shingen and their battles at Kawanakajima have been romanticized as chivalrous games of wits between them. Aya is his elder sister while Kagekatsu and Kagetora are his adopted sons.
