First, give your Neko OC a distinct personality. For example, she could be really shy but have a hidden feisty side that only comes out when she's protecting her friends. Second, give her unique physical features. Maybe she has heterochromatic eyes, one blue and one green, which is rare among Nekos. Also, a special ability like super speed or the power to heal others quickly can make her stand out. And don't forget to give her a backstory that ties into the Highschool DxD universe, like she was an experiment by a rogue devil scientist.
There could be her friends. For example, a more health - conscious friend who tries to encourage her to change her slobbish ways. Or a friend who is also a bit of a foodie and sometimes enables her bad eating habits.
Well, cat neko cartoons usually have bright colors and exaggerated expressions of the cats. They can be either funny or heartwarming, and sometimes they incorporate elements of fantasy or adventure with the cats as the main characters.
