Fanbook 5 Time!
We've got Liz's Liz's Troubles. It'll be going after the other Liz Manga chapter, near the start of the series.
Then we have Becoming a Gutenberg. This goes between Johann and Zack (where the Wax Machines are commissioned) and Finishing My Highbeast and the Wax Stencils (where the first of them is delivered). I'm going to put it right after Johann and Zack, unless people think it should go after Elvira and Lamprecht Attack.
And lastly, we've got Lieseleta's Color-Mixing and Engagement Ceremonies. While this starts in P4V9 (the Autumn before Lieseleta's final year in the Academy), it ends at the end of that winter - 4 books later. I have P5V4's Brunhilde's Suggestion down as the last chapter of that winter, and I can't spot any better place to stick this chapter than after that.
