One idea could be that Kaito Kid is on a heist and Ran accidentally gets involved. She initially mistakes him for a common thief but as she spends time with him during his escape, she realizes there's more to his actions. Maybe he's stealing something that was wrongfully taken from someone he's trying to help.
Ran's sense of justice can be pitted against Kaito Kid's Robin - Hood - like stealing. He might steal from the rich to give to the poor, but Ran still sees it as wrong in the eyes of the law. Their different outlooks on right and wrong can create a complex dynamic. As the story progresses, they might influence each other's views. Ran could start to see the grey areas in the law, and Kaito Kid might consider more legal ways to help people.
One great Kaito Kid x Aoko fanfiction is 'The Hidden Feelings'. It delves into the unspoken emotions between them. It has some really sweet moments where Kaito's charm and Aoko's feisty nature play off each other in an endearing way.
The potential for a forbidden love story. Kaito's identity as a thief and Aoko's connection to the law enforcement side in a way add to the allure. It gives fanfiction writers a great canvas to paint a story of love that defies the odds and expectations.
A 'shinichi kudo x kaito kid fanfic' often explores the interesting dynamic between these two iconic characters. It could involve their rivalry turned into an unlikely friendship or a team - up against a common enemy. Writers might play with their different skillsets, Shinichi's detective abilities and Kaito Kid's thieving skills with a touch of magic.
I really like the interactions where Kaito Kid teases Conan. It's so much fun to see how Conan gets all flustered but still tries to be in control. For example, when Kaito Kid leaves behind little clues just to mess with Conan's detective skills. Another great interaction is when they actually have to rely on each other in a dangerous situation, like when they are trapped in an old building together.
Well, 'Kaito Kid x Reader: A Night of Mystery' is a really good one. In this fanfiction, the reader is drawn into Kaito's world of mystery and magic.

And 'Kaito Kid and the Reader's Adventure' is also worth checking out as it takes the two on a thrilling journey.
Rivalry is a very common theme. Kaito Kid and Shinichi are both highly intelligent characters, so their battles of wits are often central to the stories. For example, in many fics, Kaito Kid will plan a heist and Shinichi will try to stop him, creating a tense and exciting dynamic.
The OC girl might be a librarian. In the fanfiction, she often sees Kaito Kid stealing valuable books (which are actually clues for his next big heist). But she's too quiet to raise the alarm. Instead, she starts to write a fanfiction in her head about Kaito Kid's motives. Maybe she'll eventually find the courage to talk to him and understand his true intentions.
The OC girl could be a quiet girl who has a special power. She can sense Kaito Kid's presence before he appears. However, she keeps this to herself because of her quiet nature. In the fanfiction, she could be struggling with whether or not to use her power to help or hinder Kaito Kid. She writes in her journal (her fanfiction of sorts) about her internal conflict, all while watching Kaito Kid from afar with a mixture of admiration and concern.
