Biwamaru

Biwamaru is a sightless wandering monk who travels the land with his biwa in hand, yet possesses a perception far beyond ordinary sight—he can directly sense the colors emanating from the souls of living beings, allowing him to detect demonic entities lurking among humans. His biwa is no mere musical instrument; concealed within its body lies a razor-sharp blade, ready to be drawn when danger strikes. Throughout the long journey of Hyakkimaru and Dororo, Biwamaru appears at pivotal moments like a fleeting shadow, offering guidance and insight from a transcendent perspective. He sees through the joys and sorrows of the world, yet remains unbound to any place—making him one of the most memorable and enigmatic sages in the entire story.
