Short answer, no.
Long answer, no but possibly a one shot soon?
I only mention this because everyone is asking for a book 3, and I'm not totally opposed to the idea since this is my favorite "series" I've done in a while. For me it's interesting to explore Hanako's character that I've made.
However, since this book followed the manga...what would the 3rd book follow? What would happen?
Y/N got exorcised and the events following the manga happen, all in the way they're meant to.
It's just book 3 seems like a great idea but is impossible.
HOWEVER, if you all Wanna leave suggestions in the comments about book 3 ideas I will totally give those a read:)
Also that one shot I mentioned may or may not happen. I've been deciding on it for like...a year now lol.
Anyway just wanted to clear some stuff up:)
Have a good day!
