Description
Yachiyo Runami is a central figure in the anime film Cosmic Princess Kaguya!, revealed to be the true identity of the character known as Kaguya. While initially appearing as a separate, popular streamer and administrator of the virtual realm Tsukuyomi, the narrative ultimately reveals that Yachiyo and Kaguya are the same person, with Yachiyo being a future version of the princess.
Yachiyo Runami exists in two primary forms that reflect different points in her personal timeline. The younger version, known as Kaguya, has the appearance of a slim, attractive teenage girl with long blonde hair and pinkish-red eyes. Her personality is cheery, dramatic, and exceptionally optimistic. Having been on Earth for less than a week after growing from a mysterious baby found by a high school student named Iroha Sakayori, Kaguya possesses extraordinary naïveté and immaturity. She is hyperactive and fun-loving, often disobeying rules and showing complete ignorance of concepts like money. This boisterous and idealistic extrovert slowly but surely pulls the hardworking Iroha out of her shell, allowing her to finally have fun in life. Despite her initial childishness, Kaguya's innate kindness begins to shine as she matures, cooking for an exhausted Iroha and helping her chase her dreams of writing music.
The older version, Yachiyo, is the persona she adopts after weathering 8,000 years of life. As the beloved administrator of Tsukuyomi, Yachiyo is a popular streamer and songstress whom Iroha watches to find peace from her busy life. While still kind and caring, she has lost much of her carefree nature. She carries deep anguish, viewing her crash-landing in the distant past as a mistake that doomed her and Iroha to never be together. Through millennia of wisdom and experience, she has become much cleverer, orchestrating the entire events of the film to set up her fateful meeting with Iroha. Yachiyo’s most prominent trait is her undying love for Iroha, having faithfully waited 8,000 years just to be with her again.
Kaguya's role in the story begins when she is found as a baby by Iroha Sakayori. At Kaguya's fervent request, Iroha helps her start streaming in Tsukuyomi, with Iroha acting as her producer and songwriter while Kaguya becomes a streamer and singer. As the two grow closer, ominous forces lie in wait, eager to take Kaguya back to the moon. The narrative is driven by Kaguya's desire to escape her mundane life on the moon and find happiness on Earth with Iroha. Yachiyo's role is more enigmatic; she exists as the virtual realm's administrator, watching over Iroha while keeping her true identity a secret, knowing her past self would soon be with Iroha.
Key relationships define Yachiyo's character arc. Her bond with Iroha Sakayori is the emotional core of the story. Kaguya fell in love at first sight after looking down on Earth and watching Iroha. She supports Iroha's dream and takes the initiative to become an idol so Iroha can achieve her happy ending. Their relationship develops from Iroha caring for a naïve alien to a deep romantic connection, culminating in Kaguya confessing her love and proposing marriage. Yachiyo's connection to Iroha spans millennia, as she created the entire Tsukuyomi virtual reality system specifically to be able to see Iroha again after being separated by time. She also has a fluffy sea slug partner named Fushi.
Yachiyo's character development is profound and spans thousands of years. The immature and self-indulgent Kaguya grows to understand the burdens she places on Iroha, becoming more respectful of rules and accepting of life's limitations. After being taken back to the moon and attempting to return, she miscalculates and lands 8,000 years in the past. She spends those millennia spreading her love story with Iroha and writing the legend of Princess Kaguya to ensure they will one day be reunited. Despite experiencing tremendous hardships, including trauma from war, the thought of seeing Iroha again encourages her to keep living. Yachiyo eventually gives up her immortality by burying her glowing bamboo stick at the top of Mount Fuji so she can grow old together with Iroha.
Yachiyo possesses several notable abilities. As an alien from the Moon who is over 8,000 years old, she has the power to rapidly grow from a baby to a young adult in a matter of days. She can create and administer virtual spaces like Tsukuyomi, a realm where people can live different lives and freely pursue their creativity. Her consciousness can be uploaded into this virtual reality, allowing her to exist as a digital entity. She also demonstrates musical talent as a singer and performer. Perhaps most significantly, she has the ability to travel across time, though such journeys come with risks of miscalculation. Her most poignant ability is the choice to relinquish her immortality, a power that allows her to finally share a mortal life with the person she loves.
