There's no way to know for sure who the author is without more information. It could be any fan of 'Peach Girl' who was inspired to write about Kira's death.
I'm not entirely sure specifically as it depends on the author's creation. It could potentially be about a tragic end for a character named Kira from 'Peach Girl'. Maybe it involves themes of heartbreak, betrayal or some sort of conflict that leads to her death within the fan - created narrative.
I'm sorry, without more specific information, it's difficult to determine the author of the 'little girl raised by death novel'. There may be many novels with similar themes, and it could be an indie or relatively unknown work.
Since I've never heard of this book specifically, it's difficult to say who the author might be. It could be an indie author who is just starting out and this is their first unique work. Or it could be a more established author writing under a pen name or trying out a new genre.
