Well, a lot of 'hitwoman reincarnated crossover fanfic' deals with the theme of change. Her reincarnation is a huge change, and she has to deal with it. There can also be a theme of discovery. She discovers new things about the world she's in, new abilities perhaps. And then there's the theme of relationships. In the new world, she has to form new relationships, and these can be very different from the ones she had in her life as a hitwoman. For example, she might have to learn to trust people in a world where she was used to being alone and relying only on herself.
One popular 'hitwoman reincarnated crossover fanfic' could be 'The Hitwoman's New World'. In this fic, the hitwoman is reincarnated into a fantasy world where she has to use her old skills in new and unexpected ways. Another might be 'Hitwoman in a Magical Realm', which combines the idea of her reincarnation with elements of magic and adventure.
Hermione can be developed by showing her struggle to adapt to the hitwoman lifestyle. She could start out being very hesitant and moral - bound, but as she faces more challenges, she gradually becomes more confident and street - smart. For example, she might initially be against using violence but then realizes that in this new world, it's sometimes necessary for self - defense. This change in her attitude would show her character growth.
One idea could be Hermione using her magical knowledge in the world of a hitwoman. For example, she could use spells to enhance her stealth or disarm opponents in a non - magical way that would seem like the skills of a hitwoman. Another plot could involve Hermione having to take on the role of a hitwoman to protect the wizarding world from a dark force that is using the muggle underworld to its advantage. She would have to adapt to the hitwoman's code while still maintaining her own moral compass from the wizarding world.
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.
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.
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.
One popular 'hitwoman oc fanfic' might be 'The Silent Assassin'. It has a well - developed hitwoman character with an interesting backstory. Her relationships with other characters add depth to the story.
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.
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.
