I have eight episodes. Ep 8 had an omatase for ep 9, so I know there is more of it; but more is not (yet) fansubbed. Argh etc.
ANN reports that there are 25 episodes. Unfortunately the fansubbers, Ayu, has dropped it.
But they are doing Kenkou Zenrakei Suieibu Umisho, and there are 13 episodes of that, so we're about halfway through it already.
(Interestingly, they say that they are "in process" with Ikkitousen: Dragon Destiny, though I recall hearing that I:DD had been licensed. Hmm.)
