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.
