Atsuo has a similar hairstyle to Anko's only it's blond instead of black, and his clothing is similar in color, but wears pants instead of a skirt. He also doesn't possess snake powers unlike Anko, but is still referenced in a different way. He does however possess similar kunais (ninja throwing knives).
