Rinzu

A girl who serves the Mountain God was rescued after being abandoned in the mountains as a baby. She was raised by the Mountain God and received intensive training in the spiritual technique known as "Soul Channeling." She also possesses the ability to freely wield martial arts skills that are at least on par with those of Jinka Yamato. When she first met Jinka Yamato, she fell in love with him at first sight. She refers to Tama as "Big Sister" and has a somewhat unusual personality, being captivated by Jinka Yamato’s cold gaze.

Between the end of the first part and the beginning of the second part, she, together with the Mountain God, was responsible for training Shinsuke Hyoudou. When Shinsuke Hyoudou and Senya attempted to escape, she tried to stop the Mountain God from killing them.

When she reappears eight years later in the second part, she has matured into her late teens or around twenty and now possesses a calm and composed demeanor. She continues to interact gently with the Mountain God and has taken on the role of mediator.
