Bio:
A woman that was intended to heal Takakura, by his wife Kenreimon-in, after the loss of Aoi. She was initially in a relationship with Grand counselor Lord Takafusa when he was a lieutenant, but after she was summoned by the emperor, she chose discretion and ended the relationship. This man (Takafusa) loitered around the palace, which was brought to the attention of Kiyomori. This infuriated Kiyomori because the two men that are in love with Kogo are married to his daughters. Kiyomori forces Kogo into exile and forbids her from the returning to the emperor.
Takakura found her and brought her back to the palace, stashing her in a secret location. She was able to give birth to princess Bōmon-in before Kiyomori banished her from the palace to become a nun.
