Himari is an attendant assigned to Philia in the Parnacorta Kingdom, proficient in stealth techniques as a ninja. She possesses long black hair and black eyes, standing shorter than Philia and presenting a comparatively younger appearance.

Her personality shows minimal emotional expression, slightly more than Philia's but less than typical levels. This subdued affect may result from ninja training, though potential connections to Philia's own upbringing under neglectful conditions cannot be entirely ruled out as a factor.

When assigned by Philia to monitor and protect Mia, Philia's younger sister, Himari becomes actively involved in Mia's schemes against their former homeland. She provides covert assistance enabling Mia's revenge objectives targeting Julius and the Adenauer family.
