Emperor Daigo
After the death of his wife Princess Kinshi, Morosuke married Princess Gashi, and when she died Princess Yasuko, all of whom were daughters of Emperor Daigo, thus further deepening his ties with the imperial line. Because he had affairs with and then married three different imperial princesses, Morosuke may have been the model for a character in the "Utsubo Monogatari", the ultimate lecher, Fujiwara no Kanemasa.
