So I created the Laplace Factor wiki page a while back, and there was a statement that someone born with Laplace factor could not wear touki, but in LN Volume 9, Sylphy was shown wearing touki. Feel free to start a discussion thread here, we might be able to find an answer (or maybe point out that it was a plot hole)
