Question about Naruto Ultimate Ninja Storm 2? + 10 points!?

I don't know how to do this at all, I think the buttons would be the same for every character, but here is the question. Whenever I play sasuke and go into his ultimate awakening, what buttons do i press to use the black chidori and the pheonix flower jutsu (the moves i can't use, as normal orochimaru sasuke)? I looked all over google and no one tells me what buttons to press. Also, if the buttons for the ultimate awakening jutsu are different for every character, what are they? Thanks!
