Kōsha Saraba (皿場 工舎, Saraba Kōsha) is the tenth retainer of the Yanari Shogunate.
A small girl with a look of depression.
She admits her sword - Seitō Hakari - is useless, and Shichika Yasuri suggests to throw it at him, which he deflects, knocking her out.
Swordsmanship Specialist: Saraba is said to have illusion powers, though this has not been confirmed.
- Kōsha is the only retainer who seems to survive Shichika's storming of the castle, being knocked out instead of being dealt a deadly blow. Humorously, one might attribute her survival due to Hakari's defensive focus or lack thereof.
