[citation needed] She was the legal wife of Kobayakawa Takakage, third son of daimyō Mōri Motonari.

[citation needed] Lady Toida was born as the daughter of Kobayakawa Masahira – the head of the Numata-Kobayakawa clan, which was the head family of the Kobayakawa clan – but because Masahira died at the young age of 21, her older brother, Shigehira, succeeded the Numata-Kobayakawa clan seat, but Shigehira became blind at a young age.

In 1550, he was detained by Ōuchi Yoshitaka and Mōri Motonari under the suspicion of liaison with the Amago clan, and he was forced to retire and enter the priesthood.

In 1551, Lady Toida was married to the third son of Motonari, Takakage, who was adopted into and succeeding the Takehara-Kobayakawa clan.

Her posthumous Buddhist name is Jikōin Gekkei Eichi (慈光院月渓永智).
