Sengoku Basara 2 introduces Naoe Kanetsugu as a pathetic Joke Character a la Dan Hibiki. Koei doesn't like one of their main trio getting reduced like that, as a result, they snap back at Capcom by making two of Basara's poster boys (Yukimura is also Koei's poster boy, so he's out of question) underlings of Orochi that you need to beat down and label 'bad guys'. Not to mention Masamune, being the more 'main' poster boy of Basara, is turned into a worshipping fanatic of Orochi, stripping all his Badass points in his KOEI incarnation (it's less than the Capcom one, but STILL).
