I mean... My story is a furry, fantasy, adventure/romance/drama with some sci-fi elements later on.
And if that wasn't niche enough we have polyamorous trio as main characters in the narrative.
Albeit, the reason i'd consider it niche, is none of the above.
The idea behind JTA is to get a really in-depth look at the characters... I always feel like fantasy and adventure tends to focus a lot on the world and epic wars and battles that go in the background, and too little on characters.
In my story I wanted to be a bit different, the trio is not about to save the world at the start, and even after being developed, the core of their motivation will usually sit around trying to help others and the strugles they go through to be good people in this strange world they live in where dragons are super powerful and control the lives of everyone.
This is not the standard adventure, every character has a number of layers, and many things about their personality are made splicit, but so many more are hidden in the details... Like the way they talk and the words they use is often carefully deliberate to express something, the way they fight, their magic and habilities and the way they treat their enemies, everything is made with a purpose. (and this goes for both the heroes and villains, side characters or main characters)
I never wanted my readers to read a page and feel like 'nothing happened today' every chapter from the busiest and most action packed fight scenes to the calmest and most chill and mundane says something about the characters and helps you piece the puzzle of who they are.
I made it this way because I wanted readers to not feel like they saw...'yet another fantasy adventure', with predefined roles associated to every character like 'the muscle, the heart, the leader' and so on and so forth.
Instead, you see every character from the perspective of the others, and in their own perspective they are their own protagonists so other characters roles may vary... You are essentialy encouraged to piece together your own image of the characters based on the perspective of the people who interacted with them (which includes themselves)
One more detail i might add that i think makes it niche... I wanted this to be a less romantic view on romance.
I like the idea of love, but not in the dramatic way a lot of dramas do it... Characters are more grounded in that front to, with their love being expressed subtly as opposed to trying to make it sound like a poem, the realism of the work people put into love is the thing i tend to focus more on.
In a sense... I guess I could call it a more 'realistic' fantasy with cute animal people and dragons. ^^
