Anri Sonohara is a major character in the light novel and anime series Durarara!!. She is a bespectacled girl who attends the same school as Mikado Ryūgamine and Masaomi Kida. She is rather quiet and timid, but appears very close towards Masaomi and Mikado. Although possessing a tendency to seclude herself from others, she is intelligent, clever and resourceful. Her full figure and shy behaviour gives her the unwanted attention of many males (though she doesn't do anything about them). Her online chat screen name is "Saika".
