Rin

Rin (リン) is a supporting character in the original series. Her earliest memory of her childhood is her family being slaughtered before her eyes. Shocked by the tragedy, she was unable to talk and helped her local village by taking care of prisoners. When Bat and the "water thief" Kenshiro are thrown into jail, Rin watches over them. Once Kenshiro learns her past, he unlocks pressure points around her head to allow her to talk again. Like Bat, she chooses to follow Kenshiro in his travels. She has a strong sense of clairvoyance and a maternal sense of protection in spite of her age.

She eventually grows into adulthood as a freedom fighter against the oppressive Holy Emperor army. In memory of Kenshiro, they dub their group the Hokuto army. She has romantic feelings for both Kenshiro and Bat.

During their fight against their adversaries, Rin learns she is a descendant of the Holy Emperor bloodline, a family which rules over the Hokuto, Nanto, and Gento constellations. She reunites with her sister, Rui, and seeks to restore peace with Jako's defeat. Before they can celebrate, Rin is suddenly kidnapped and eventually held prisoner within Shura by Kaioh. Kenshiro and Bat embark on a tiring quest to save her.

Fighting Style
Rin does not fight with her fists throughout the series. Her pacific rational, however, is capable of calming some of her obstinate opponents. As she matures, Rin learns to defend herself with a crossbow and basic kicks if necessary.

Hisashi Koinuma more or less accepts her as the Yuria figure of the second arc. He thinks of her as a weaker version of Mamiya.
