An intelligent and broad-minded Horse Girl. Influenced by her father, a famous trainer, and her education-focused mother, she is interested in nurturing the next generation. Learning that Tiara Horse Girls often focus on training successors after retirement, she admires this as her ideal path. According to her roommate and best friend, her "On/Off" switch is extremely distinct.

Usually, she carries herself with a mature, resolute attitude and speaks with a gallant tone, though she uses proper honorifics with superiors and seniors. While she is fundamentally serious, polite, and reliable, her switch between "On" and "Off" is quite sharp and reportedly surprises those around her.
