(This is unexpected in Umamusume, but instead of Horses, they are Fighting Roosters: The Shuratori)

The camera pans over the city of Ōsaka at night: neon lights illuminating the Dōtonbori neighborhood, digital posters of female wrestlers, clandestine bets running on hidden screens. A narrator's voice sounds deep:

Narrator: “In a world where the blood of ancient roosters runs in the veins of these girls, wrestling is not just a sport… it's pride, tradition, and survival. Welcome to the Age of the Shuratori.”

📢 RINGA Arena – Ōsaka Dome

Thousands of spectators scream in a packed stadium. In the center, a circular steel ring awaits the next battle. Giant screens project stats and clips of the debuting wrestler.

The lights dim, a single lamp focuses on the entrance hallway.

📢 Announcer (Rooster International New Generation Arena): “Ladies and gentlemen! Prepare to welcome the most anticipated debutante of the season! Straight from the mountains of Nagoya, raised in the oldest dojos of the Shamo lineage… Introducing… the iron hen… SHAMO KURENAI!!!”

A thunderous blast of Japanese drums and modern guitars shakes the venue. She strides forward, wearing combat boots and red feathers adorning her hair. On her back, she wears a long coat with a golden emblem of a flaming rooster.

📢 Commentator: “Kurenai is pure bloodline! Trained to withstand blows that would break normal bones, her style is aggressive and ruthless. Everyone is betting on her tonight!”

Meanwhile, in another dark corner of Ōsaka, in an abandoned warehouse, an illegal fight is brewing. The atmosphere is different: smoke, bets under the table, bills changing hands. There are no introductions here, just a tense silence before the fighters are thrown into the makeshift ring.
