How so? The ending animation changed, it was originally mostly about Kohaku, Tsukasa, and Hyoga, all replaced with Suika. In the original shot the trio was chilling on the grass under the full moon, now we know why. Hyoga was too dead to raise his hand to the sky, Kohaku was dying on her belly, and also the hand looks too masculine to be Kohaku's or Suika's. So I think it's just Tsukasa pulling a nando demo, or maybe no one in particular.
