That is also kind of like how the one nude scene in Bleach, which some parents would be all up in arms over, over here, I get no sexual undertones from either. It is the one where Rangiku comes out from the bath to comfort Orihime, a girl bonding moment persay. It fits Rangiku's character as she is not ashamed of her body and Orihime is also female. Actually, the same goes with Rangiku's intereaction with her small taicho. Some people feel that she's sexually harassing him, when she's really not.
