Roba

Roba is the old woman in the small Russian village. Her son was killed by chiropteran and she knew that Sonya was a monster. She warns Saya and later attempts to kill Sonya with an axe. But since Sonya is a chevalier, she heals and murders Roba.

Years later, when Saya journeys along the trans-siberian railway, Amshel first takes the appearance of Roba. While getting on board, Riku and Hagi assist the Amshel disguised as Roba.
