ByaRuki

The ByakuyaxRukia pairing from the anime Bleach. Because Rukia is Byakuya's adopted sister and sister-in-law, some fans consider it to be a form of incest; however, since they are not blood-related, most shippers do not consider it so. It has grown to become a considerable and dedicated following in the Bleach community.

In some instances, ByaRuki can refer to platonic "sibling" love instead of romantic love. Usually this occurs when a person considers the couple too taboo to be an actual pairing.
