Marin Kitagawa is the main female protagonist of My Dress-Up Darling and a popular, outgoing high-school student who is passionate about anime, games, and cosplay. She has long, dyed blonde hair that fades into pinkish-red at the ends, dark-brown eyes that she usually wears pink contacts over, and a fashionable gyaru-inspired style. Marin is cheerful, energetic, friendly, confident, and very open about the things she loves. She strongly dislikes people who judge others for their interests and is especially supportive of people who aren’t comfortable expressing their hobbies. She can also be impulsive, messy, clumsy, and easily distracted, but she becomes extremely determined once she sets her mind on something. Her main ability is cosplay—she has a strong eye for character details, makeup, fashion, and posing. Marin is also a model and has considerable knowledge of styling, photography, and presenting herself in front of others. Her greatest strengths are her creativity, confidence, enthusiasm, and ability to encourage others to embrace what they love.
