Initially a carefree Ronin who rooms with Hyakkimaru and Dororo at one night, Saburota wants to join Daigo for some unexplained reason. He is later revealed to be a minion of the Fiends and works for them to earn himself a heart.
As a FiendEdit
He is fought in Chapter 7: Tragedy. You do not receive a body part for killing him as he is not, strictly speaking, a Fiend.
Created by the Fiends to defeat Hyakkimaru, he has no heart, and cannot travel in areas the Fiends do not control. In areas they do control, he has absolute power.
