Well, his tail in fanfiction could be a sign of vulnerability too. Writers might use it as a way to show his softer side. For example, if someone were to grab his tail, it could make him feel really uncomfortable or even weak. It could also be a way for him to show affection in a non - human way, like wagging it when he's happy around Kagome.
In some fanfictions, Inuyasha's tail could be a magical object. It might hold secrets or memories from his past. There could be spells or curses associated with it. Writers could create interesting plotlines where his tail is the key to unlocking a hidden power or a long - forgotten mystery about his heritage. It could also be a way for other characters to manipulate him, by threatening or using his tail in some way.
His relationship with other demons could be affected too. They might see his tail as a sign of his strength or weakness. Some demons might be envious of his tail if it has special powers. Others might try to use it against him in battles or to gain some advantage over him. It could also be a way for Inuyasha to bond with other half - demons who also have unique physical features like a tail.
A cool plot might be that a dark wizard from Fairy Tail discovers a spell that can open portals to other dimensions and accidentally pulls Inuyasha, Kagome, Shippo, etc. into their world. The Fairy Tail guild decides to help them get back home. But during this time, they realize that there are some similarities between the demons in Inuyasha's world and the dark creatures they fight in their own world. So, they team up. Inuyasha and Natsu could have a friendly rivalry over who is stronger and in the end, they combine their powers to defeat an ancient evil that was awakened by the portal - opening spell.
One interesting Inuyasha tail fanfiction could be about how Inuyasha's tail has a special power that he discovers during a battle. Maybe his tail can sense danger before it arrives and it starts to twitch, warning him and his friends. Another could be a story where his tail is the key to unlocking an ancient spell that has been long forgotten in the Feudal Era.
The tail could be a symbol of his uniqueness. Maybe it sets him apart from other characters in the fanfiction world. It might also have some magical properties, like being able to sense danger or hidden magic.
It could be really exciting. Imagine the powerful mages from Fairy Tail meeting the demon - slaying Inuyasha. They might team up to fight a common enemy, like a powerful dark mage who has made a pact with some of the demons from Inuyasha's world. The magic of Fairy Tail and the spiritual powers and swords in Inuyasha could create some really cool battle scenes.
There could be a fanfiction where the magic system in Fairy Tail is introduced to the world of Inuyasha. Kagome might learn some Fairy Tail magic, like fire - based magic similar to Natsu's, which she could use to enhance her powers against demons. This would create a whole new dynamic in her battles and relationships within the Inuyasha world.
One common theme is the clash of different power systems. Inuyasha has his demon powers and sword skills, while Fairy Tail has magic. So, in many fanfictions, they explore how these powers interact, like whether Inuyasha's Tessaiga can cut through Fairy Tail's magic barriers.
Finding good Inuyasha tail fanfiction writers can be a bit of a hunt. One way is to look for writers who have been writing in the Inuyasha fandom for a long time. They usually have more experience and can create more detailed and engaging stories about Inuyasha's tail. Another tip is to look for writers who are not afraid to explore different aspects of Inuyasha's character through his tail. For example, those who write about his emotional state as it relates to his tail, or how his tail affects his relationships with other characters. You can also follow the recommendations of other Inuyasha fans who have similar tastes in fanfiction.
