>is kazuha the only normal?
basically. hints dropped over time indicate she may or may not use various massage toys in the restroom.
so in context, very normal. she is clearly a high T girl, and this often equates to being a horny freak. so she hides it will and/or satisfies her desires in a healthy way, consistent with how pure and healthy she is.
