The name "Naomi" has it's origins in Hebrew and Japanese. It means beautiful, pleasant, delightful, and gentle. I've known two women named Naomi. A Puerto Rican girl who was a foul mouth bitch, and a Japenese girl who was the most beautiful girl I've ever known.
While Mistress Haru is beautiful and probably pleasant and delightful, I have my doubts about the gentle part.
