Sai Ka is the wife of Ou Hon, the mother of their child, daughter-in-law of Ou Sen, a Great General of the state Qin and Six Great Generals's Third Great, and the lady of the house for the Ou Family's main branch
A beautiful woman with long black hair, Sai Ka appears to be a young woman in her 20s and she is usually shown wearing extravagant clothing and robes commonly worn by nobility.
In contrast to her husband's afloat demeanor and stuck up attitude, Sai Ka is a flexible, cheerful and outright kind woman.
Introduced in v61's omake of the series as Ou Hon's fiancée (Much to the outrage of his admirers), Sai Ka would later be introduced as his wife in the main story after marrying him in the aftermath of the Western Zhao Invasion Arc and his promotion to the rank of General.
2 years later, Sai Ka was mentioned by Mou Ten as he told Ri Shin, Ka Ryo Ten, and Kyou Kai about her and Ou Hon's marriage which sent the Hi Shin's General into an unforgettable shock and was later reveled to have become a mother after safely giving birth to their child.
- Sai Ka first appeared in volume 60's omake.
