I love Kingdom Hearts more than I can say. One of my absolute favorite series. I love it to death, and it makes me feel stupid. My favorite character is Riku, no question. In fact, Riku is my favorite fictional character, PERIOD. Has been for quite a few years now, and I imagine he still will be for a long time yet. My other favorite characters are Namine, Aqua, Terra, Leon, and (for some reason) Zexion.
