I'm glad Can't Fear Your Own World is being translated. I've been wanting clarification on a few things left unexplained in the Bleach universe, especially since I've been binging the series again recently.
It does bother me that many of these plot threads have been tied up in novel format rather than in the manga itself. And that could be for a number of reasons, but I'm still firmly encamped in the 'Kubo was rushed to finish Bleach by his editors at Jump because it was selling well' territory, so he didn't have the time to expand on the things he wanted to, like Matsumoto's past, for example (she's his favorite female character).
Regardless, I hope the anime finds a way to incorporate some of these details into its' storytelling. That is, if the novel doesn't get animated as well.
