Some of my faves:
http://www.mangago.zone/read-manga/vassalord/ (action, mistery, supernatural, shounen-ai, 35 chapters)
http://www.mangago.zone/read-manga/roureville/ (supernatural, a bit of action at the end mixed with a mistery, shounen-ai, 24 chapters)
http://www.mangago.zone/read-manga/yasashii_ryuu_no_koroshikata/ (fantasy, shounen-ai, 20 chapters, translated untill ch. 17, but I recommend you to still read it because most of the plot's conflicts are solved)
http://www.mangago.zone/read-manga/koori_no_mamono_no_monogatari/ (shounen-ai, fantasy, 82 chapters)
http://www.mangago.zone/read-manga/asterisk/ (supernatural, shounen-ai, 27 chapters)
And this one is also a great one. http://www.mangago.zone/read-manga/1001_nights/
But it's not fantasy, supernatural or action. It's more "adventure" which gives off the same vibes of a fairytale's. It has 11 volumes and despite being categorized as a tragedy, the ending is a happy one, where the protagonists end up together

Thank you very much
Thank you for your recommendations!!
Happy new year!! Can anyone tell me about a good long manga, maybe action or fantasy but sort of yaoi, shounen ai but that the focus of the manga is actually a story not the yaoi or shounen ai part.
