what is the kingdom hearts com

I can answer your 2nd question.

It's a GBA game and takes place shortly after Kingdom Hearts. It takes place in Castle Oblivion and is based around memories, and some more stuff to do with Riku and others. It reveals more about the cloaked figures you would have seen in KH2 trailers. It ties the gap between KH and KH2.
