What I meant when I said 'only one', was that this syou work was the only pure yuri work (i.e. no guys taking part in the sex) in the subscription service. There are the Isya and Asagi Ryu books, which I already own (and a couple of western made comics that I don't care about.) The 13 USD per month subscription service is worthless to me (and, I suspect, others) without more regular yuri additions, and a sufficiently large back catalogue of yuri.
As for lewd yuri magazines, there are some. There's
"Aya Yuri",
"L - Ladies and Girls Love",
"Love Girls", and a few others. Sure, none of them publish monthly, but they do exist and I am sure OKS Comix and others could supply enough enough content to make a Fakku sub worthwhile for a yuri fan.
Failing that, I would love to see Fakku slap a price tag (3 USD?) on each the few yuri chapters they do get, and let me buy them. I just don't see how a sub makes sense for a yuri fan right now.
