What’s in a Chaos Origins Booster Box
Chaos Origins (set code CORI) is a Yu-Gi-Oh OCG core booster that released in Japan on April 25, 2026, per Konami’s official product page. A sealed box contains 30 packs, and each pack holds 5 cards, for 150 cards per box. The official tax-inclusive MSRP is ¥198 per pack (¥180 before tax), which works out to ¥5,940 per box (~$39) at official retail — that’s Konami’s list price for the structure of the product, not a price we’re quoting for our own stock.
The set totals 80 unique cards across the standard rarity ladder, before any of the set’s parallel treatments are counted:
| Rarity | Card count |
|---|---|
| Ultimate Rare | 4 |
| Ultra Rare | 8 |
| Super Rare | 10 |
| Rare | 18 |
| Normal | 40 |
| Total unique cards | 80 |
On top of that base ladder, Konami layers three parallel treatments across the set: 24 cards get a Prismatic Secret Rare treatment, 30 cards get a Secret Rare treatment, and 4 cards appear as special “overframe” prints in Prismatic Secret Rare. These are alternate print treatments of cards already in the 80-card pool, not additional unique cards.
First-production boxes carry one more thing worth knowing about before you buy: a bonus “+1 Expansion Pack” containing one card drawn from a 15-card pool of higher-rarity reprints, including four cards with new artwork. It was included with the initial print run.
Chase Cards in Chaos Origins
The verified card highlighted here spans several of the set’s top rarity tiers. We’re covering it by rarity tier, not by pull rate or market price — Konami hasn’t officially confirmed pull rates for this set, so we don’t treat any pull-rate figure as fact.
Black Luster Soldier – Soldier of Light and Darkness (CORI-JP028)
This card is printed across multiple rarity tiers within the set: Ultra Rare, Secret Rare, and Prismatic Secret Rare, including an overframe version. That places CORI-JP028 among the set’s verified chase prints without conflating its treatment with Quarter Century Secret Rare.
For the complete 80-card list with every rarity variant, see our CORI Chaos Origins card list. Our CORI pull-rates and best-cards article goes further into community pull-rate discussion — we don’t repeat those figures here since Konami hasn’t confirmed them, but it’s a useful companion read if that’s what you’re after.

Regular Box vs Damaged Box vs No Shrink on Our Site
We list sealed Japanese booster boxes under a few different condition categories, and it’s worth knowing what each one means before you order. Our Damaged Box category is a condition tag we use specifically for cases where the outer box — not the contents — has been affected in shipping or handling. The booster packs inside stay factory-sealed; the change is cosmetic to the outer box only, never to what’s sealed inside it. Regular and No Shrink listings sit apart from that: a regular listing is standard factory-sealed stock, while No Shrink refers to boxes where the outer shrink wrap is no longer present even though the box itself is unopened.

Is the English Chaos Origins the same set as the Japanese one?
They share the same set name, but Yu-Gi-Oh’s Japanese (OCG) and English (TCG) print lines don’t always carry an identical card pool or release date. Konami’s TCG page lists the English Chaos Origins at 100 cards against the Japanese set’s 80 card types, so the two are not the same card list.
