Nene Saikyo

Nene Saikyo (also romanized as Nene Saikyou) is a character from Chivalry of a Failed Knight (Rakudai Kishi no Cavalry).

She is a teacher at Hagun Academy, hired by its director Kurono Shinguuji (her former rival). Nene ranks as the third-strongest Blazer in the KOK A-League and is famously known by the nickname "Yaksha Princess" due to her immense power, sadistic tendencies in battle, and violent reputation—even law enforcement hesitated to confront her in the past out of fear of the destruction she could cause.

Despite her fearsome combat prowess, she has a surprisingly child-like and playful personality, often being sharp-tongued, teasing, and absent-minded (sometimes insulting others without realizing it). She appears petite and youthful for her age (early 20s), frequently dressed in a kimono, which adds to people mistaking her for much younger.

In the story, she serves as a powerful mentor-like figure at the academy with a mix of intimidating strength and quirky, teasing behavior.
