She is typically depicted with long, flowing silver or light blue hair that reaches down to her waist. Her eyes are usually a striking red, which adds to her mysterious and somewhat otherworldly presence.

Where did she flee from?

Eirin Yagokoro fled the Lunar Capital primarily to protect Kaguya Houraisan, whom she had a deep bond with. The Lunar Capital is a place of strict order and perfection, and when Kaguya consumed the Hourai Elixir, which granted her immortality, she violated the laws of the moon. As a result, Kaguya was exiled to Earth. Eirin, being one of the Lunar sages and Kaguya’s close confidante, couldn't bear to leave Kaguya alone on Earth. To ensure Kaguya's safety and to accompany her in exile, Eirin abandoned her position and fled the Lunar Capital. This decision marked Eirin as a traitor to the moon, but it also solidified her loyalty and devotion to Kaguya. Together, they settled in Eientei, a hidden mansion in the Bamboo Forest of the Lost on Earth, where Eirin continues to protect and care for Kaguya.

relationship with Reisen

Eirin Yagokoro shares a mentor-student and caretaker relationship with Reisen Udongein Inaba. Reisen, a former moon rabbit who fled the Lunar Capital during a war, was eventually found and taken in by Eirin and Kaguya at Eientei. As a mentor, Eirin trains Reisen in various skills, particularly in medicine and combat. Eirin's teaching style is often strict and disciplined, reflecting her high expectations. Despite this, she genuinely cares for Reisen and sees her as a valuable and loyal ally. Eirin often relies on Reisen to carry out tasks and missions, trusting in her abilities. Reisen, in turn, respects and admires Eirin, viewing her as a wise and powerful figure. She is deeply loyal to Eirin, often addressing her with honorifics and following her orders without question. This relationship is built on mutual trust and respect, with Eirin serving as both a guiding figure and a protector for Reisen.

relationship with Tewi

Eirin Yagokoro's relationship with Tewi Inaba is somewhat complex, combining elements of mutual respect and mild frustration. Tewi, the leader of the Earth rabbits at Eientei, is a mischievous and cunning character known for playing pranks and being somewhat unpredictable. Eirin, who values order and discipline, often finds Tewi’s antics troublesome. Despite this, she recognizes Tewi’s importance and influence among the rabbits of Eientei. Eirin appreciates Tewi's knowledge of the Bamboo Forest and her leadership over the Earth rabbits, understanding that Tewi's actions, while often playful, are generally beneficial to the household. Tewi, on the other hand, respects Eirin for her wisdom and authority, but she doesn’t hesitate to tease or play tricks on her, knowing Eirin won’t take it too seriously. The dynamic between them is characterized by a balance of Eirin's patience and Tewi’s playful nature, with Eirin often tolerating Tewi's behavior because of her usefulness and loyalty to Eientei. In essence, their relationship is a mix of professional respect and a certain degree of informal camaraderie, with Eirin often playing the role of the patient elder dealing with a mischievous, younger subordinate.

Relationship with Kaguya

Eirin Yagokoro and Kaguya Houraisan share a deep and multifaceted relationship rooted in loyalty, mutual respect, and a long history together. Eirin is not only Kaguya's protector but also her closest confidante and friend, a bond that was solidified when Eirin chose to abandon the Lunar Capital to stay by Kaguya's side on Earth. Eirin's relationship with Kaguya can be seen as a blend of mentor, guardian, and equal. As a lunar sage, Eirin once held a position of great authority, and she uses her wisdom and knowledge to advise and care for Kaguya. Despite this, she treats Kaguya with great respect, acknowledging her status as a princess and an immortal being. Eirin’s actions are often motivated by her desire to ensure Kaguya’s well-being and happiness, even if it means going against the Lunar Capital or taking extreme measures. Kaguya, in turn, deeply trusts and relies on Eirin, viewing her not just as a servant or caretaker, but as a true companion. Their relationship is one of mutual dependence; while Kaguya enjoys the freedom of her exile on Earth, she relies on Eirin's guidance and protection. This bond is also characterized by a deep emotional connection. Eirin’s decision to flee the Lunar Capital with Kaguya was driven by more than duty—it was an act of devotion to someone she cares for deeply. Kaguya, aware of the sacrifices Eirin has made for her, reciprocates this devotion with her own form of care, often in more subtle ways, as they navigate their lives in Eientei together. In summary, Eirin and Kaguya share a relationship built on loyalty, mutual respect, and a profound bond that transcends the typical master-servant dynamic. They are partners in exile, with a connection that has endured for centuries.
