Hien

A female ninja from Thorman who serves as Shuro's escort. 26 years old. Her real name is "Naka". She has two stars, but her actual rank is just below Maizuru. She is tall and has a sisterly personality. Both her parents are servants of a semi-main family, and she has known Shuro since childhood. Although she says she has no romantic feelings, she was shocked when Shuro confessed to having someone he likes. She is skilled and adept at handling things, somewhat confident and has a sparse empathy for others, but her abilities as a ninja are solid. She weighs as much or more than Kaburu, judging by her height and BMI, yet she demonstrates acrobatics light enough to use Kaburu as a foothold.

She was the first casualty in the Battle of Farin, her body signaling a turning point in the battle.
