This is a translated version of "Kouryuu Densetsu Villgust - Kieta Shoujo."  The "[En by Magic Destiny v1.0]" addition indicates a fan translation patch, making the Japanese game playable in English. Magic Destiny is likely the fan group responsible for the translation.  The gameplay remains consistent with the original Japanese version, but now includes English text and menus, improving accessibility for English-speaking audiences.  The original Japanese game's developer and publisher would be the same as the untranslated version.
