@Fermi I pretty much agree with that one guy, and I also agree that the change was a little exaggerated. However, Helen was not the one who was burned at the stake. She desperately didn't want to die, so her father decided she needed to feel the weight of losing someone close to her. Heaven didn't want to die, but the loss of Helen would have been too great of a burden for her to take.
Heaven was always the perfectly good saintess who loved her sister.
Helen was the rebellious child that didn't care about this entire saint thing and just wanted her sister.
Helen going full "I want your cock" is a bit jarring -_- but her being a "bad girl" is accurate
...because ✨MAGIC✨
