A traveler at heart with boundless curiosity. She often sets reckless itineraries and disappears on spontaneous wanderings, sometimes not returning for long periods.

Highly social with a wide circle of friends. She speaks in a detached yet calm manner, but she's a good sport and laughs often. Sometimes uses poetic phrasing related to travel. A unique Horse Girl who is aware of her counterpart in a parallel world (the racehorse Stay Gold). Because of this, her words and actions are often mysterious. She looks after Dream Journey, Nakayama Festa, Orfevre, Gold Ship, and Fenomeno—who are her offspring in historical fact—as her younger sisters. Appearance: Very petite build. She has dark bay semi-long hair, but the back is longer than her shoulders and tied in a single ponytail.

She's a sentimentalist of the old school, deeply compassionate, with a heart that cherishes plants and small animals, and a side that worries about her younger siblings back home. She reportedly likes food stalls in back alleys that serve tripe stew. Also, her aforementioned mentor (her elementary school homeroom teacher) is said to be seriously ill, and she frequently goes missing, claiming to be "visiting the sick." She is a partner-in-crime with Gold Ship and often joins in on her pranks. Speech: A bit masculine and affected, like a professional gambler. Appearance: Messy long bay hair with violet eyes. A gray knit cap is her trademark. The cap has holes for her horse ears to poke through.
