Jin is a character from the anime series Sisters of Wellber. He is introduced as a key companion on the central journey, serving as a travel partner to the main characters, the princess Rita and the thief Tina.

Described as a boy who is initially mute, Jin possesses a calm and mysterious demeanor. He is characterized as being cheerful, bright, and generally kind towards women. However, this friendly nature has a notable exception; Jin shows hostility and jealousy towards any handsome man who becomes close to Tina. His actions are deeply tied to Tina, as he is identified as both her partner and her lover.

Jin’s role in the story is directly connected to his relationship with Tina. He is protective of her, and his primary motivation revolves around their bond. His background includes an origin from the country of Sangatras, though further specific details about his past are not prominently detailed.

Throughout the series, his development is closely linked to his relationship with Tina and the larger group of travelers. As the group overcomes various dangers on their way to the magical center of Wellber, his character is defined by his loyalty and his willingness to fight for what he believes in. He is a skilled fighter, often seen wielding two katanas, and he has a habit of smoking. While he possesses a strong sense of justice, he is also not afraid to use violence when necessary.
