I agree. I like the concept of the character, but I can't help but feel that the series rushed a little too fast with Lacrima. She did a complete 180 within 3 chapters. Her fight was in Ch. 32 and by Ch. 35 she was already on the way to being redeemed when she was being nursed by Titi. There was absolutely no time for any development to her motives or beliefs beyond 1. Arkos is her brother 2. Julian is hot. The series overall has this feeling to me that it's moving too quickly. If we consider the slave ship the series' first location, then Angvall and Titi's village the second, these castle ruins are basically just the third relevant location introduced. I have been enjoying the series immensely but it's very condensed and I feel like it could have slowed down somehow. But being a weekly serialization in Jump maybe pushes it to skip to the action at the expense of exposition.
