Perhaps a tattoo of a cherry blossom tree. In Japanese culture, cherry blossoms are symbols of renewal and the transient nature of life. In the context of Kagome's story, it could represent her constant movement between two different worlds, the modern world and the feudal era, and how she has grown and changed through her experiences in both.
It could be a design of Inuyasha's sword. Since he and Kagome have a deep connection, she might get a tattoo of his sword as a symbol of their relationship and the adventures they've shared together. It would also represent strength and protection, just like the sword itself.
A design of the Shikon Jewel fragments could be another option. Kagome has been involved in the search for the Shikon Jewel for a long time. A tattoo of the jewel fragments could signify her role in that journey and the power she has come across during that time.
The tattoo could also be a part of a deal she makes in the fanfiction. Suppose she has to make a pact with a powerful being in the feudal era. As a result, she gets a tattoo that binds her to the deal, and throughout the story, she has to figure out how to fulfill the terms of the pact without sacrificing her own values.
It could be a way to remember someone important. Perhaps she lost a dear friend or a mentor, and the tattoo is a permanent reminder of them. For instance, if it's a portrait - like tattoo of her master Tsunade, it would show how much she respects and misses her, and how Tsunade has influenced her life and growth as a ninja.
In the 'harry gets a tattoo fanfiction', he might get a tattoo as part of a bet or a dare. His friends challenge him and, being the brave Harry we know, he accepts. The tattoo could be something really out - of - the - ordinary, like a moving image of his Patronus. This could lead to all sorts of adventures as he tries to hide it from the more conservative members of the wizarding world.
It could be about Ginny's journey to get a tattoo. Maybe she has a specific design in mind that has a deep personal meaning, like a symbol representing her family or a memorable event in her life.
One possible plot could be that Felicity gets a tattoo as a symbol of a new beginning in her life. Maybe she's had a rough break - up or a major life change and the tattoo is her way of reclaiming her identity. For example, she could get a small butterfly on her wrist, representing transformation.
Well, perhaps in the fanfiction, Kagome's sickness is a result of some dark magic. Her getting sick could be a part of an enemy's plan to stop her from interfering in their evil deeds. Her friends then have to not only deal with her illness but also figure out who is behind it all and stop them before it's too late.
A possible plotline could be that Sesshomaru has to prove himself worthy to Kagome's family and friends. Since he has a reputation as a somewhat cold and aloof demon, this won't be easy. When Kagome gets pregnant, it adds more pressure. He has to show that he can be a reliable partner and father. Meanwhile, Kagome is trying to figure out how to combine her modern - world knowledge with the ways of the feudal era when it comes to raising a child.
Maybe a symbol related to her medical skills. In the Naruto series, Sakura becomes a great medical ninja. So, a caduceus or some other medical - related symbol like a cross with a leaf (representing the herbs she might use in her medical practice) could be tattooed on her upper arm. This would show her pride in her profession.
Well, one possibility is that Harry gets a tattoo to symbolize his journey. Maybe it's a lightning bolt on his wrist, representing his scar and the battle against Voldemort. It could be a secret among his friends at first, and they discover it during a Quidditch celebration.
It could be a wizard who is an outcast from the mainstream wizarding society and has made a living by using his magic in unconventional ways, like tattooing. He might have a small, hidden shop where only those in the know can find him.
