Description
Lady Ruri, also referred to as Princess Ruri or Ruri-hime, is a supporting character who appears in the Nue arc of the anime Mononoke, which spans episodes eight and nine. She is the sole heir to the Fuenokouji school of incense, a traditional art known as kōdō. As a noblewoman, she resides in a mansion in Kyoto, where she becomes the central figure in a competition meant to determine her future husband.

In terms of background, Lady Ruri is positioned as a prize to be won by one of four suitors who gather at her mansion. The competition takes the form of an incense identification game called Genjikou, which draws on the literary tradition of the Genji Monogatari. The suitors are not motivated by genuine affection for her but by their desire to gain control of the Todaiji, a legendary artifact believed to grant immense power to its possessor. Lady Ruri herself appears to be a passive figure in this arrangement, with little agency over the events unfolding around her.

Personality-wise, the available information does not provide a detailed portrait of Lady Ruri as an individual. She is presented more as a symbolic figure or a catalyst for the arc's events than as a character with a fully realized inner life. Her motivations are not explored in depth, and she does not drive the narrative through her own actions or decisions. Instead, she functions as the object of the suitors' ambitions, and her role in the story is largely defined by how others perceive and pursue her.

Lady Ruri's role in the story is primarily that of a victim. During the incense competition, a murder occurs, and it is later revealed that Lady Ruri herself has been killed. The mononoke responsible for the deaths is a nue, a shape-shifting spirit that takes on the forms of three different women throughout the arc: Lady Ruri, her servant, and a mysterious girl. The nue uses these disguises to manipulate the suitors and trap them within the mansion grounds, forcing them to endlessly repeat the competition unaware that they are already dead. Lady Ruri's identity is thus co-opted by the mononoke, and she becomes one of its masks rather than an active participant in her own story.

Key relationships in the arc are defined by the dynamics between Lady Ruri and her suitors. The suitors, who represent different social standings and ambitions, view her as a means to an end rather than a person worthy of genuine connection. This transactional attitude is central to the horror of the arc, as their greed and lack of empathy leave them vulnerable to the nue's illusions. Lady Ruri's relationship with her servant is also relevant, as the nue impersonates both women, blurring the lines between mistress and attendant.

Development for Lady Ruri as a character is minimal. She does not undergo a personal transformation or gain deeper insight over the course of the arc. Her death occurs early in the story, and subsequent appearances are the work of the nue mimicking her form. This lack of development is noted by some commentators as a weakness of the Nue arc, which focuses more on atmosphere and visual storytelling than on character depth.

Notable abilities or traits specific to Lady Ruri herself are not described in the source material. Her significance lies in her status as the heir to a prestigious school of incense and her role as the target of the suitors' ambitions. The artistry of the arc uses her appearance symbolically, with her eye makeup rendered as one of the few brightly colored elements in an otherwise muted palette, suggesting her connection to the supernatural events at play.

Overall, Lady Ruri functions as a plot device within the Nue arc. Her presence sets the stage for the competition, her death triggers the mystery, and her form is appropriated by the mononoke to further its deception. The story does not explore her personal background, inner conflicts, or relationships in any meaningful detail, leaving her as a largely passive figure whose true character remains opaque.
