Guideverse novels that have a Hunter/Gate-like setting AND BL (Boy x Boy) romance. This list originally included BG romance but has since been separated into two lists because of the sheer number of BL series.They could use the terms like Awakener, fight monsters, go into Gates/Dungeons, or basically be indistinguishable from regular Hunter novels except that they have Esper/Sentinel & Guide powers. Series that have related elements (monsters invading Earth from other dimensions even without Gates/Dungeons, etc.) are also included. A lot of Guideverse novels are kinda borderline on whether or not they're "Hunter/Awakener", and some series' settings technically have Hunter elements but the Hunter stuff is never actually seen in-story and might as well not exist at all. This list has those too.
