The video cycles through 2 loops of characters:

• Danon Decile
• Urban Chic
• Shahryar
• Stars on Earth
• Stunning Rose
• Hayayakko
• Deep Bond
• Do Deuce (Second loop only)
• Regaleira

As a roulette animation, it's impossible to use notes, so the translation will be comments in this format:

Character said:

Something something

Danon Decile said:

The Derby wasn't a fluke!

"It'll soon be the age of me!"

Urban Chic said:

I announce the new generation!

"And next year's leading actor will be me!"

Stars on Earth said:

Freed from the outer gates at last!

"I will shine once again like the first-magnitude star that I am!"

Stunning Rose said:

I shall bring glory to the Rose family!

"For my finale, I shall bloom once again!"

Hayayakko said:

Is it the fast white gal's time to shine!?

"The first Grand-Prix for a white horse girl is mine for the taking!"
Indeed, Hayayakko is the first white horse to participate at the Arima Kinen. Sodashi never did, being more of a miler.

Deep Bond said:

To maintain the bonds, Everyone's "Pubo-chan" will go all out!

"16th time is the charm! For Pubo's glory!"

"I'll show you the dream from 64 years ago!"
Being the winner of the 2024 Arima Kinen, Regaleira is the first 3-year-old filly to win the Arima Kinen since 64 years ago.

Do Deuce said:

The Supreme Commander of Japan's counterattack!

"My dream hasn't ended just yet! Even at the end, I'm the strongest!"
What if... Due to lameness at one of his legs, Do Deuce was scratched from the 2024 Arima Kinen.
