Otsukishi

Otsukishi is a fictional term used in Japanese-inspired fantasy media to denote a legendary order of warriors linked to the moon. It is not a real historical organization.

In most depictions, the Otsukishi serve as guardians of celestial sites, keepers of lunar lore, and scouts who travel by night. They are often bound by an oath that emphasizes restraint, honor, and protection of civilians during darkness.

Common iconography includes a crescent moon or full moon against a field of pale blue or silver, worn as a sigil on helmets or banners. Equipment varies, but they are frequently portrayed wearing lightweight, night-blue plate armor and wielding sabers, spears, or moon-bladed weapons.

Fictional portrayals show varied organization: sometimes a loose brotherhood; other times a formal order with ranks, lodges, and a leader known as the Moonwarden or Grand Lunar. Their duties include patrolling travel routes at night, performing ritual lunar rites, and assisting in guiding lost travelers.

Appearances span novels, video games, and tabletop RPGs; in some stories they cooperate with rulers or temples; in others they operate as independent enforcers of night safety.

While the name is often treated as a proper noun in translated works, etymological roots are not standardized; authors may interpret the name as combinations of elements meaning moon, night, and knight. The usage varies by work, and there is no canonical origin.
