Oh... it's you. What do you want?
Tamamo is depressed.
Tamamo is first seen in the Cave of Treasures in Part 1, but it turns out to be nothing but a fake, a recording essentially from the original timeline to trick Nanabi into guarding the bell. As soon as the ruse is pointed out, it is dispelled and the puppeteer, White Rabbit appears who explains this was so events follow the correct history.
Tamamo is properly met in Yamatai Village at the Kitsune Shrine, just like in the original trilogy. However, she's not the same as she once was. Her help won't be as forthcoming this time round.
