Well, the OC hitwoman is the central figure. But in many 'khr oc hitwoman fanfic', characters like Xanxus can be important. Xanxus may see the hitwoman as a potential tool or a threat to his power. Also, Squalo could be involved, as he might be sent to either recruit or eliminate the hitwoman. Additionally, the female characters from the KHR world, like Chrome, could play a role. Chrome might sense something different about the hitwoman and try to understand her better.
One popular 'khr oc hitwoman fanfic' might be the one where the OC hitwoman has a unique backstory that ties into the KHR world's power structure. For example, she could be an assassin hired by one of the mafia families in the KHR universe to take out a rival. Another could be about an OC hitwoman who is actually on a quest for revenge against those who wronged her family in the KHR setting. And there might be a story where the OC hitwoman teams up with some of the main characters from KHR to take on a greater evil that threatens both her world and theirs.
She could interact with Tsuna. Maybe she is initially hired to target him, but as she gets to know him, she realizes he's not what she expected and ends up helping him instead.
Another character could be a long - lost relative of Kushina. This character might show up in the fanfic with an even deeper understanding of the adamantine chains. They could come to the Hidden Leaf Village to teach Naruto or other young ninja about the true nature and power of the chains, which could lead to all sorts of new adventures and battles.
It depends on the specific fanfic. But usually, it would likely include characters from Katekyo Hitman Reborn! like Tsuna, Reborn, and his friends. Since it's a 'gamer' fanfic, they would be the ones engaging in the gaming activities.
The theme of identity is also prevalent. A hitwoman OC often has to balance her true self with the persona she presents to the world of crime. For example, she might have a normal life outside of her hit - job, and the struggle to keep these two identities separate is a key part of the story.
It could work if there was a cross - over event that forced Hermione into this new role. Maybe some dark magic from the KHR world affected her and she had to use her skills to survive in this new, more violent world. She might start using her wits and magical abilities to take out targets that were a threat to her newfound situation. And with her determination, she could quickly rise to be a formidable hitwoman in that fanfic world.
Well, if it follows the typical KHR pattern, there might be Tsuna and his friends. They could be the ones being babysat. And the babysitter could be an original character created specifically for this fanfic. This new character would then interact with Tsuna and his gang, leading to various interesting situations.
One possible plot could be that Hermione, with her intelligence and quick - learning ability from the Harry Potter world, gets drawn into the complex underworld of the KHR universe. Maybe she starts as an outsider but quickly rises as a hitwoman due to her unique skills. For example, she could use her spell - casting knowledge in a way that mimics the special powers in the KHR world, allowing her to outwit her opponents.
She would gain a new sense of self - reliance. In the Harry Potter books, she had Harry and Ron to rely on. But as a hitwoman in the KHR fanfic, she'd be on her own most of the time. This would force her to trust her own instincts more. She'd have to make quick decisions without the input of others, and this would shape her into a more independent and perhaps even more dangerous character.
Typically, you'll find Sith Lords like Darth Vader or Darth Maul associated with Sith City in fanfic. They are the powerful and feared figures that would be at home in such a dark place. Their presence would add to the overall sense of danger and the dark side's power.
