Forbidden Light is one of the last main-series Sun & Moon expansions before the era moved into its GX-heavy back half, and it’s still one of the SM-era boxes we get asked about by name. 拡張パック「禁断の光」— Expansion Pack “Forbidden Light,” set code SM6 — uses a main numbered run with secret-numbered cards above it.
This guide covers exactly what’s in a Forbidden Light box, which cards collectors actually chase, how our own Damaged Box and No Shrink listing categories apply (or don’t) to this set, and where the box sits between Japanese and English releases. We ship Japanese sealed product out of Tokyo, so the pricing below reflects the current listing — not a market estimate.
Forbidden Light (SM6) is a Sun & Moon expansion with 5 cards per pack and 30 packs per box, plus an official guarantee of 1 SR-or-better card per box. The headline chase is Ojou-sama SR 100/094, alongside Greninja-GX, Ultra Necrozma-GX, Karune and Xerneas-GX. Our SM6-Forbidden Light Japanese Pokemon Booster Box is currently listed at ¥68,250 (~$429), and the full Pokemon box range is browsable on our Pokemon card box collection.
The one listed price in this guide is our current listing as of September 2026, converted at ¥159/USD.
What’s in a Forbidden Light Booster Box
| Item | Value |
|---|---|
| Set name (JP) | 拡張パック「禁断の光」(Expansion Pack “Forbidden Light”) |
| Set code | SM6 |
| Era | Sun & Moon |
| Cards per pack | 5 |
| Packs per box | 30 |
| Box guarantee | 1 SR-or-better card per box (official) |
The main numbered run goes up to 094, and secret-numbered cards sit above it — the pattern you’ll see below is card numbers like “100/094,” where the denominator marks the main run and the numerator extends beyond it. For the card-by-card breakdown, see our Forbidden Light (SM6) card list.

As a standard-format Sun & Moon expansion pack rather than a high-class pack, Forbidden Light doesn’t carry the wide Art Rare / Special Art Rare secret pool that later high-class sets are known for. The box’s draw is a smaller, more concentrated group of SR chase cards, covered next.
Chase Cards in Forbidden Light
Five cards are the reason collectors still open this box:
Ojou-sama SR 100/094

Ojou-sama (おじょうさま) is the set’s current headline chase — a supporter-class SR that anchors most Forbidden Light discussion. This single is not currently listed on our site; sourcing requests go through Quick Order.
Greninja-GX SR 95/094

Greninja-GX sits at the low end of the secret-numbered run, one of the set’s GX-tier SRs. This single is not currently listed on our site; sourcing requests go through Quick Order.
Ultra Necrozma-GX SR 99/094

Ultra Necrozma-GX is the set’s original 2018 mascot attacker, and it’s usually the second name people bring up after Ojou-sama when talking about this box. This single is not currently listed on our site; sourcing requests go through Quick Order.
Karune SR 101/094

Karune (カルネ) is a trainer-class SR near the top of the secret-numbered run. This single is not currently listed on our site; sourcing requests go through Quick Order.
Xerneas-GX SR 98/094

Xerneas-GX 98/094 is the Secret Rare print of this card in Forbidden Light, sitting in the secret-numbered run above the 094 main-run denominator. This single is not currently listed on our site; sourcing requests go through Quick Order.
None of the five cards above are currently listed as graded singles on our site. For the pull-rate math and a fuller ranking across the set’s secret tier, see our Forbidden Light pull rates and best cards guide — that article covers the EV side; this one covers box facts and where to buy.
Regular Box vs Damaged Box vs No Shrink on Our Site
Across our catalogue, we use two extra condition categories alongside a standard sealed listing, and it’s worth knowing what each one actually means before you buy:
- Damaged Box — a condition category we use for sealed booster boxes where the outer box itself, not the contents, is affected. The booster packs inside stay factory-sealed; nothing about the sealed contents changes. You still get the same booster packs, in the same box count, just with a mark, dent or other cosmetic issue on the outer packaging. Damaged Box pricing moves independently of the regular box listing and isn’t always cheaper.
- No Shrink — this is a listing name we use on a handful of product pages for boxes sold without their original shrink wrap. We don’t have a broader definition of the term beyond that; it’s a condition label attached to the specific listing, not a separate grading system.
For Forbidden Light specifically, only the standard sealed box is currently listed — there is no Damaged Box or No Shrink listing for this set on our site at the moment. If you’re after either variant for SM6, requests can be flagged through Quick Order (no timing on availability).
The regular sealed box is currently listed at ¥68,250 (~$429).
