Her parents were sheltering her in elementary school, but once Eiko pointed out that playing outside and experiencing the world isn't a bad thing, they realized they were wrong. After that they let Kamuri do things she wanted to do, not just study/piano practice/etc. and thanked Eiko when Kamuri met her again in high school. They still buy Kamuri really cute clothes, but with a daughter that cute and adorable I think that's understandable.
