About this product

The Umamusume: Pretty Derby booster brings the series’ characters to UNION ARENA, with newly illustrated cards showing Uma Musume in special UNION ARENA outfits. It also features foil-printed reproductions of signatures from the voice actors, including those of Special Week, Silence Suzuka, Tokai Teio, and Oguri Cap.

A serial-numbered, limited Action Point card with an actor’s handwritten signature is planned as a very low-probability, quantity-limited inclusion. The cards are randomly packed, and parallel cards are also available.

Summarized with the help of AI from the official product page. Contents can change before release.

Where to buy it

New booster packs sell out fast in Japan. Official stores and electronics stores often sell them by lottery, with purchase limits and ID checks. Card shops may still have boxes or packs after release day, usually at shop prices. Single cards from the set are easiest to find at card shops.
