Maybe the OC is a florist. Kaito Kid sometimes passes by the flower shop. One day, he enters to buy some flowers for a disguise or just out of curiosity. The OC and Kaito start to talk and a gentle relationship forms. The OC could teach Kaito about the meanings of different flowers, and Kaito might use this knowledge in his heists in a creative way, while also maintaining a sweet connection with the OC.
The OC could be a librarian. Kaito Kid, in his search for some rare books related to magic or his heists, visits the library often.

They might share stories about the books, with Kaito Kid revealing some of his more intellectual interests that are related to his criminal activities in a very soft - spoken way.
Perhaps the OC is an artist who often witnesses Kaito Kid's stunts. The OC is fascinated by Kaito's grace and starts to draw him. Kaito notices this and they develop a gentle relationship. For example, Kaito might leave little notes for the OC near the scenes of his crimes, complimenting the art.
Friendship is also a common theme. The oc and Kaito form a unique bond, whether it's as partners in crime or just as good friends. And of course, there's the theme of self - discovery. The oc often discovers new things about themselves while being around Kaito. For example, they might find out they have hidden talents for solving mysteries or performing magic tricks. The interactions between the oc and the existing characters in the Kaito universe help to explore these themes in depth.
