There are three endings for both Kisuke's and Momohime's stories. Although I haven't seen the third ending yet (don't spoil it!), I'm assuming from this vid that each has their own unique final boss. The second final boss is a fight with the other playable character in the game, in this case Momohime. This, I believe, was a much more fitting final battle than that mutated dog... thing, albeit much shorter and easier.
Believe it or not, this was played on Shura (Hard).
EDIT: I have recently seen Kisuke's third ending. I once again fought Tokugawa Tsunayoshi as the final boss, so I didn't really bother capturing that fight again (although I would love to do it on Shura instead of Muso...). Same with Momohime, where you will fight Fudo-Myoou again instead of another boss.
Eh? How do you get to fight Momohime? :< I can't figure it out.
