Now updated to include the prequel manga Orfina Saga.
Here’s a direct link to the newly added Orfina Saga section.
Orfina (12 volumes + 8 Orfina Saga volumes + Orfina Rquniecca, all complete)
Orfina spanned 12 volumes and spawned a prequel named Orfina Saga , which went 8 volumes.
(Orfina Saga has now been included in the gallery above and also in the download all link.)
There is also a semi-hentai spinoff which appears to be by the same mangaka, entitled Orfina Rquniecca . Since it’s probably canon (or close enough), I went ahead and included it with the compilation of the main series.
