Tamamo Cross

A horse girl with a trademark of fangs, blue spherical hair accessories, and a blue headband with red checks. She has long gray hair. Her nicknames are "Tama" and "Tamamo." Her roommate is Oguri Cap. She refers to herself as "Uchi" and speaks in a Kansai dialect. She is both a rival and a close friend of Oguri Cap. She is admired by her juniors, Oguri Cap and Super Creek, and often makes witty remarks in response to their natural airheadedness.

Her family was so poor that they couldn't afford meat and had to use fish cakes as a substitute. Both her parents worked, and she wanted to make life easier for them and her younger siblings with the prize money from the Twinkle Series. Because of this, her obsession with victory is intense, but it negatively affects her performance. Additionally, due to her small appetite and petite stature, she can't build a strong body, and she struggles to win races before her debut due to being easily overpowered.
