Maybe it's a tale of survival, showing how the lion uses its claws to overcome difficult circumstances in a harsh environment.
It could be an adventure story where the lion's claws play a crucial role in facing challenges.
I'm not sure specifically as I haven't read this particular fanfic. It could potentially be about a lion that, despite facing challenges or perhaps being in a weakened state, still retains its strength and ability to fight represented by its claws.
There's no way to tell exactly without reading the fanfic. But given the title, the lion is surely a main character. If it's a fanfic within a certain fictional universe, there could be other well - known characters from that universe involved. For example, if it's related to a magical world, there could be wizards or other magical creatures that cross paths with the lion. Or if it's set in a more natural - world - based fictional context, there could be other predators or animals that the lion has relationships with, either friendly or adversarial.
In this fanfiction, one can expect to see the lion character showing its power and using its claws in various situations, perhaps in battles or to protect something it values.
It could be that the main character is a human who has a special connection with the lion. The lion's claws play an important role in their relationship, like the human is the only one who can touch the lion's claws without getting hurt. So, while the lion is central because of its claws, the human's story is intertwined with it.
It could be a fantasy fanfic where Naruto's animal form is a lion to give him unique powers and abilities.
It could be a story of friendship where they overcome their differences and become unlikely pals.

I'm not entirely sure as 'ryuu lion fanfic' could be about a lot of things. It might be a fan - made story related to a character named Ryuu who has lion - like qualities. It could involve adventures, a unique world - building, or relationships within the context of this Ryuu - lion concept.
Maybe it's a story of friendship and loyalty. The king and the lion could have overcome many difficulties because of their strong bond.
