Short black hair. Yellow drooping eyes. Has a tail and horns. Fifth in order of the Sui, the third daughter. Holds the authority of Wisdom. She is the one who bestowed names upon the other Sui (the reason for this naming was so the agents would not be called 'the nth Sui.' It is an expression of the establishment of self-awareness). An agent of Sui. She cooperates with Yan through teaching and proofreading work. As her words "What is important is what I have left behind" suggest, she has devoted herself to conveying wisdom, knowledge, words, and script, refining the Yan script and pushing for the spread of education. She left behind many books and legal copybooks so that everyone could read and write. Shu says she "looks graceful but is actually smarter than anyone." Xi says she is "nagging and always acts like an older sister." She has strong sibling love and a very strong spirit of self-sacrifice. When dining at a wine house with her siblings after a long time, she drank more than usual and showed a playful side, such as imitating her drunk older sister Ling by writing poetry on the wall. She also has a sense of humor among her siblings. She possesses a Scribe's Blade with extraordinary authority that can erase, correct, or alter memories, existence, and thousands of years of history. Even compared to other agents, her authority is prominent; despite her being gentle and contributing to the common people, Yan considers her someone they wish to subject to immediate and necessary "disposal." Regarding the Scribe's Blade, she mentions, "The reason I keep this blade is simply because I want people to remember that there is always a chance to correct mistakes. That is all." She is the type who is very good at understanding anyone and making them feel understood, and she loves helping people. When her emotions are heightened, she becomes quite sharp-tongued. Speaks in a polite, formal tone. First person: I (polite) Calls younger sibling agents: [Name]-kun, [Name]-chan (Shu-chan). Calls older sibling agents: [Name]-niisan, [Name]-neesan. "Bamboo slips and paper will both surely decay one day. No matter what it is recorded on, it can only be preserved eternally once the written word remains in human memory." "When judging a crime, one might consider extenuating circumstances... but when it comes to the description of history, that is a different matter. The reason I decided to study history and script was, in the end, because I wanted to understand the true nature of the 'human heart' from them. I wondered if the true intent behind the words, the truth behind the historical materials, might hide the answer to the hesitation in my own heart... Not for Yan, not for this land. Much less for my family... just for my own hesitation—"

Long hair. An agricultural Tianshi of Yan and a leading Tianshi of the Tianshi Mansion. A meddlesome, sisterly figure who shows concern not only for her siblings but for everyone around her.

She is also a good cook and often serves food to others. An agent of Sui. The fourth daughter who established her ego sixth. Female. Height 165cm. Birthday is June 6th. She has a strong obsession with being an older sister, saying things like, "Hmm? I'm the big sister, obviously. I'm sixth in the sequence of twelve. That means I'm a big sister," which is somewhat difficult to understand. If pressed on this, she exerts silent pressure. Naturally well-versed in agriculture, she also enjoys fishing. She is knowledgeable in divination and can perform accurate future predictions by reading palms through her authority. Note that if you ask her to look for something bad with this power, you will see her strict side. The green onion-like stick she holds in her right hand as a weapon is a ceremonial jade tablet called a "Gui," used as a symbol of authority. In contrast, the mysterious cube she holds in her left hand is modeled after a traditional interlocking wooden puzzle called a "Lu Ban Lock." Calls younger sibling agents by their names without honorifics. Calls older sibling agents: [Name]-niisan, [Name]-neesan (Jie-neesan). "There's no need to feel regret. Fallen petals become soil, nourish the roots, and new flowers bloom again the following year. A hundred rivers reach the sea, and the departed are just like that. Yet they turn into clouds and rain, changing form to return to the mountains. Even if the ends of this earth are covered in a blanket of snow, the cycle of causality does not stop. From beneath the accumulated snow, the buds of spring will burst forth."
