Well, now thanks to RWBY Chibi, we know that "This book is filth! FILTH!!!"
This is just me but to me I think Ninja's of love is just something Blake wants to keep for herself. I myself have books that I keep to my self that include smut and or sex
R.I.P Ruby's innocence
Although, considering RWBY Chibi is non-canon, can we really say if it's been confirmed that it's a smut book?
I recall someone on the RWBY crew saying, back during volume 1, that Ninja's of Love is a dirty book, like the books that Jiraiya writes in Naruto, or something like that.
Confirmed... it was in an extra(either stream or DVD idr)
It was said to be a Naruto reference by Monty in the Volume 1 Directors Commentary. The only thing that it could reference really is the Icha Icha series (the ones Jiraiya writes).
there was a later reference which clarified that further by M&K at a later time too... maybe it was a chibi Stream I'm thinking of.
Plot twist: IT'S A TRAP!
