Star Wars: Every Sith Who Turned To The Light Side
5. The Ronin
Star Wars: Visions may have been a bit hit-and-miss, but it kicked off with the phenomenal Kurosawa-themed episode, The Duel. The short centres around a former Sith, simply called The Ronin, who went into self-imposed exile after he witnessed the collapse of his brethren in the Sith rebellion. After moving to the Outer Rim Territories with his droid, R5-D56, The Ronin lived in relative peace and chose not to discuss his past.
But when his village he was invaded by the Sith, Kouru, The Ronin was forced to intervene and eliminate her. In the closing moments of the episode, we see The Ronin has multiple red kyber crystals - the energy source of a Sith's lightsaber. This heavily implies The Ronin has killed several of his former clan and has turned himself into a Sith hunter.
