Maybe not destined to become female again but at least Matsuri was a female in the past.
But how/why one of Suzus don’t remember about past female Matsuri?
Little Suzu absolutely only wants Matsuri to be a male, she insists everytime about this.
I thought it was because she fall for him when he was little but she also has all her past memories so she knows about past female Matsuri.
The question is why she says nothing about it?
