For the anons in the thread who had been asking why Louis sent Monica specifically to guard the Second Prince, it's written as part of the Epilogue for Volume 1. I predict that the anime will simply gloss over most of it and probably just have Ryn ask why Louis made Monica guard the Second Prince, with Louis just saying that Monica is actually a monster above geniuses and that he wants to 'bully the strong' and end it just at that
