 Princess Yasuko came to see Narihira off, and they were never to see each other again, though it is said that Princess Yasuko bore a child as a result of the brief love affair.It is not precisely clear when the Saiō system ended, but what is known is that it occurred during the turmoil of the Nanboku-chō Period when two rival Imperial courts were in existence, in Kyoto and Yoshino.The Saiō system had been in steady decline up to this period, with Saikū reverting to just another rural rice farming village after the system's collapse.
