There are many interesting fanfictions centered around the Manticore in Lost Girl. Some might focus on its backstory, like how it came to be in the Lost Girl universe. Others could explore its relationships with other characters, perhaps its interactions with Bo or Dyson.
I'm not sure specifically as there could be various interpretations. It might be about human distrust ('ningen fushin' can be related to lack of trust in people) in a fictional context, perhaps exploring relationships and the consequences of such lack of trust within the story.
I'm not entirely sure as it could be a rather niche or new series. It might be about some unique characters or a particular world created by the author. Without more information, it's hard to say specifically.
I'm not sure as I haven't read this specific story. But generally, if'manticore' is a mythical creature, the'sting' could be related to some kind of action or event in the story that involves this creature's stinging ability.
A common theme is the struggle for acceptance. Since manticores are often seen as fearsome creatures, female manticores in fanfiction may face difficulties in being accepted by other beings.
The manticore is a mythical creature. In its origin story, it is often described as having the body of a lion, the face of a human, and a tail like a scorpion or a spiked tail. It was said to be a fierce and deadly beast from Persian mythology. It was feared for its ability to kill with its stinger and its strength.
Since we only have the title 'mister little cave story', the 'mister' could be a variety of characters. It could be an old hermit who has made the little cave his home. Or it could be a young adventurer who is exploring the area and stumbles upon the little cave. Another possibility is that 'mister' is a scientist who is studying the cave for geological or ecological reasons.
As I haven't read the 'ningen fushin novel', it's difficult to name the main characters. But generally in a story about such a concept, there could be a protagonist who is deeply affected by the ningen fushin around them. There might also be supporting characters like friends or family members who either contribute to the distrust or try to help the protagonist break free from it.
