Xing Hou is the mysterious assistant to Fei Wang Reed (or Fei Wong Reed). Little is known about her except the fact she is partly a "failed creation." However, as the story progresses her character has more depth. In Volume 15 of the manga she helps the real Syaoran go to Yūko after he awakened (Volume 09 of ×××HOLiC), but stated she can only do it once. Her reason to him was "If the dream does not end."
