I don't like to post unfinished files I get from P2P, but this one has been stalled since a long time already. Apart from the usual lewd material, Uchida-san gives some preliminary drawings of an ill-fated Reyon Densetsu Gaiden OVA project (Gaiden? finish the main story first dude!).
Out of the total 56 files of the original archive, because of the data holes 4 files are missing entirely (37, 38, 44, 47) and 3 (36, 43, 46) are incomplete, you still have a reasonable taste of the full thing. Anyway if someone can find the complete doujin on his archives please upload!
When I watched Lyon Flare years back, I found the art and look of the girls amazing for a old OVA but the scenes did not had appeal to me. The sequel/remake was a bit better but it lost the appeal of the original story and art, plus tentacles if matters :P
