Someone already said it before, but I need to put it here to make it easy to find. There's a channel called Ayamari kinoko (f. k. a. Mahina Kurosaki), that uploads subbed Kiryu stuff and currently has these DVDs: "Hyakkiyakou", "Onmyourouka" and "Ryuuchoukouga" (the show and the documentary). Also, this channel on Biliblili has "Saika gaisei" and "Gekkasuisou".
