I dunno what is the plan for the bunny girl but her character is just too flat, like you can predict what is she gonna do. I get it that she is a fan service when she was an extra but she became an important character in the story when she joined the mc's party, its unfair that her character arc will stay the same.
I really like when they were watching the healer girl be corrupted. Its just like they are reading their favorite book.
