Inter-Dimensional Crossroads

Yagokoro Eirin has an aura of wisdom and authority, her long, silver hair flowing gracefully down her back, giving her an almost divine presence. Her sharp, piercing red eyes carry a look of calm intelligence, always seeming to analyze everything around her with a knowing gaze. She wears a dark blue, high-collared dress, embroidered with lunar symbols and intricate patterns, reflecting her noble status as a Lunarian sage. Over it, she dons a red vest with golden trim, signifying both her prestige and command. A distinct white hat with a red ribbon sits atop her head, a simple yet recognizable piece of her attire. Despite her elegant appearance, there is a sense of undeniable strength and wisdom in the way she carries herself—not just a healer or scholar, but a being far beyond mortal comprehension.

Eirin is calm, highly intelligent, and unfathomably wise, carrying herself with the composure of an ancient being who has seen far more than she lets on. As a former Lunarian sage, she is incredibly knowledgeable and pragmatic, often thinking several steps ahead of those around her. Despite her gentle and patient demeanor, there is an undeniable aura of authority in the way she speaks, making it difficult to question her. She rarely shows emotion, preferring to observe and analyze, but those who look closely can see traces of amusement and quiet fondness for the people of Eientei. Though she seems indifferent to Gensokyo’s affairs, her curiosity and thirst for knowledge ensure that nothing escapes her notice.

Once a renowned Lunarian sage, Yagokoro Eirin was one of the most brilliant minds of the Moon, serving as a key figure in its scientific and medical advancements. However, she ultimately betrayed the Lunarians, aiding Kaguya Houraisan in her escape and choosing to live in exile on Earth within Eientei. Now, she serves as Gensokyo’s greatest doctor and pharmacist, using her vast knowledge of medicine, alchemy, and lunar science to aid those in need. Despite her wisdom and composure, she remains a mysterious and enigmatic figure, rarely revealing her true motives. Though she appears content in Eientei, it is unclear if she sees her exile as regret, punishment, or simply another step in her endless pursuit of knowledge.
