Natsume Amano is a minor supporting character and Ichigo Amano's younger sister. She is excellent at the piano, and that's why at the beginning of the story Ichigo shows some jealousy because of Natsume's talent. Natsume is often giving Ichigo advice, as seen when Ichigo asks her sister if she'd learn a complicated piece if someone was better than her.
Natsume is shorter and younger than Ichigo and has large golden brown eyes with light brown hair and a pale complexion like her parents.
Natsume is a talented young girl, she is not as clumsy as Ichigo and unlike her sister bares a unique talent at the beginning of the anime. As mentioned by Ichigo the two sometimes fall into arguments and are like rivals, the two also rarely share a moment of sisterly love. However Natsume does seem to love her sister a lot deep down and Ichigo is the same. She later thanks Ichigo when Ichigo shouts a message of support to Natsume while she is struggling to play the piano as her hands go numb (causing their mother to get quite annoyed and Ichigo making a fool of herself.) She also stands up for Ichigo's dream alongside Kyouko, her mother, when her father Shigeru disapproves of Ichigo moving to St.Marie Gakuen. In the last episode of series 1, Natsume attends Ichigo's contest with her parents and when Ichigo wins with her Strawberry Tart againist Team Francis, she runs up to Ichigo and the two sisters hug each other.
