Queen Kei sends Seishin to Hou with letters addressed to the interim ruler - Gekkei.  It is expected that he will be in charge but he has no inclination to do so.  After hearing Seishin and reading the letter from Shoukei, the princess that he let live, he changes his mind and decides to take on the role of interim king of Hou.  Seishin also delivers a letter to Queen Kyou asking for forgiveness for Shoukei.  Shoukei instead gets banished from the kingdom of Kyou but that in itself is something as she is no longer hunted for her crimes.
