When a series is good enough, you can just watch it from start to finish in one session. Ryuuou is just that sort of series. Once the blu-ray came out, there was nothing left that could stop me, so I just watched the hilarious yet dramatic and intense sports romance from beginning to end.
The only problem with this show is that the 'end' isn't the real ending, it's just the beginning of the story. The real story continues ever onwards from here, but the anime suddenly stops. It's a very unfulfilling feeling.
Ryuuou's counterpart, Hikaru no Go, got like 75 episodes. Ryuuou deserves just as many, not this lame 12 ep nonsense.
Nor are any of the Ryuuou light novels translated beyond where the anime stops, so there's simply no way to continue this story from here. It's a detestable situation.
But at the very least, people should take advantage of what we do have, 12 golden episodes of virtually perfect storytelling, based off the two time winner in a row of the best light novel in Japan contest. My own stamp of approval is just one of an endless chorus of stamps that virtually everyone on Earth has given this franchise already.
