Well, start with the appearance. In Darker than Black, the look of the characters can be quite distinct. Your OC could have a signature look, like a particular style of clothing or a unique hair color. Then, there's the matter of their moral compass. Are they on the side of good, bad, or somewhere in between? This can add a lot of depth to the character. And don't forget about their weaknesses. A character with flaws is more relatable. Maybe your OC has a fear of a certain type of ability or a psychological weakness that can be exploited. This will make them more complex and interesting in the fanfiction.
One plot idea could be an OC who discovers a hidden conspiracy within the Syndicate. They start to uncover secrets that could change the balance of power in the Darker than Black world. Another idea is an OC Contractor who has lost their memory and is trying to figure out their past while being hunted by other Contractors. Or, a plot where an OC is a normal human who gets caught in the middle of a war between Contractors and tries to find a way to bring peace.
