Kappa's Nostrum

Kappa's Nostrum

Kappa's Nostrum is a powerful healing ointment said to be created by cutting off the arm of a kappa. Unshou received the nostrum from a kappa in exchange for what he believed to be a pair of kappa arms.

He then became a doctor and used the Nostrum to miraculously cure the injures of the village residents and, on one occasion, Marisa's arm wound.
