Some forget the reason Chikane raped Himeko was so she would no longer be a virgin and thus disqualified from being the sacrifice the Orochi Necks were looking for, not to make her hate her. The other things she did were meant to make her hate her. The anime misses the point of this and screws up the original intent. If it was too rough for TV, they should have left the molestation out altogether from the anime. The manga had it correct. The anime ruined the story flow. I agree that I wish they would have spent more time on the pairs history. They could have added an episode's worth of time inserting more of how Chikane came to love Himeko and vice versa and a little less time on Himeko and Souma's relationship.
