The SM6 Forbidden Light chase cards are no longer cheap Sun & Moon pickups, and the box is no longer one you open for casual EV. The Japanese set released in 2018, production is long finished, and the chase-card hierarchy has changed: Lady SR now defines the collector ceiling, while Greninja GX, Mysterious Treasure UR, Bonnie SR, Diantha SR, and Ultra Necrozma GX round out the serious demand.
The older version of this article was outdated. It treated Ultra Necrozma GX Rainbow as the top chase, listed the sealed box around ¥9,000, and used unsupported exact EV math. Our SM6 sealed box is now listed at ¥55,825 (~$362), so the buying logic has to be different.
This refreshed guide mirrors our strongest pull-rate articles: set specs, top-card pricing, box-vs-singles advice, confirmed pull-rate facts, sealed-price context, and a clear recommendation for collectors, openers, and singles buyers.
The October 7, 2026 update adds the chase-card table and refreshes our store listings and prices; the other facts in this article were last checked on January 3, 2026.
SM6 Forbidden Light is a sealed collector box first and an opening product second. The official Japanese box guarantee is one SR-or-better card per 30-pack box, but exact HR/UR/specific-card odds are not published. With the SM6 box listed at ¥55,825 (~$362), singles are usually the smarter route unless you specifically collect sealed Sun & Moon boxes.
SM6 Forbidden Light Chase Cards: Set Overview
Forbidden Light (禁断の光) is the sixth Japanese main expansion from the Pokemon Card Game Sun & Moon era. The official product page positions Ultra Necrozma GX as the headline attacker and confirms a large 94-card base set, Kalos Pokemon support, Ultra Beasts, and a guaranteed SR-or-better slot in every 30-pack box.

What Makes SM6 Special
- Lady SR (Ojou-sama) aged into the headline chase – Japanese price aggregators placed it around ¥62,000 in May 2026, well above the old Ultra Necrozma-led framing.
- Greninja GX keeps the Pokemon-side chase alive – Greninja demand is stronger globally than most SM-era GX characters, and the HR/SR versions sit near the top of the SM6 card list.
- Ultra Necrozma GX and Mysterious Treasure matter historically – Ultra Necrozma was the set mascot and competitive centerpiece, while Mysterious Treasure remains a recognizable play-history trainer card.
The confirmed Japanese SM6 box guarantee is one SR-or-better card inside each 30-pack box. Treat any exact HR, UR, or specific-card odds as estimates, not official Pokemon data.
SM6 Forbidden Light Chase Cards: Prices and Where We List Them
The roster below is the eight SR cards from the official card database, with the lowest SNKRDUNK asks seen on October 7, 2026 next to our listings. The prices quoted in the card sections and tables further down are rounded from Japanese secondary-market aggregators in May 2026 and converted at roughly ¥155/USD for readability. Always check live listings before buying, because older Sun & Moon cards can move sharply when clean copies disappear.
| # | Card | Rarity | Lowest ask on SNKRDUNK (Oct 7, 2026) | Our listing |

The old article’s “Ultra Necrozma GX Rainbow at ¥5,000” framing is not the current SM6 market. Lady SR and Greninja GX HR/SR now dominate the value discussion.
#1 Lady SR (100/094)
Lady SR is the card that most clearly explains SM6’s modern collector value. It is a female trainer SR from an older Sun & Moon expansion, and that combination tends to age better than mid-tier GX cards. At roughly ¥62,000, it is also the cleanest reason to buy singles instead of trying to hit one specific card from sealed boxes.
#2-4: Greninja GX and Mysterious Treasure
Greninja GX gives the set a real Pokemon-character chase beyond trainer demand. Mysterious Treasure is the practical-play-history card, while Ultra Necrozma GX remains the set mascot and the card most collectors associate with SM6’s original release window.
Should You Buy an SM6 Forbidden Light Box?
The answer depends on what you are actually buying. At today’s sealed pricing, SM6 is not a “rip boxes until you profit” product. It is a nostalgia-era sealed box with one official SR+ slot and a high-value trainer chase.
| Buyer Type | Recommendation | Reason |
|---|---|---|
| Chasing Lady SR | Buy the single | You avoid paying sealed-box premium for a specific-card lottery |
| Sealed Sun & Moon collector | Check box availability | Out-of-print sealed SM boxes are supply-constrained collector items |
| Pack opener | Open only for the experience | The SR+ guarantee is real, but the box price makes EV difficult |
| Competitive-history buyer | Buy singles | Mysterious Treasure and Ultra Necrozma pieces are easier to target directly |
Treat the product page as a sealed-collector availability check: the SM6 box is listed at ¥55,825 (~$362). If your target is one specific card, use singles; the spread between the sealed box and a Lady SR single makes the tradeoff very clear.
SM6 Pull Rates & Box Math
The most important correction: we should not invent precision. The official SM6 product page confirms one SR-or-better card per 30-pack box. It does not publish the exact chance of hitting HR, UR, or a specific SR like Lady. The Pokémon Company does not publish pull rates.
Confirmed vs Estimated
| Outcome | How to Treat It | Confidence |
|---|---|---|
| SR or better | 1 per Japanese 30-pack box | Officially confirmed |
| Specific Lady SR | Rare because many cards can occupy the SR+ slot | Estimate only |
| HR / UR cards | Scarcer than normal SR outcomes, but exact SM6 rate is not official | Estimate only |
| GX / holo distribution | Useful for opening experience, weak for EV at today’s sealed price | Opening-data dependent |
The old guide claimed exact-style rates and a clean box EV figure. That is not strong enough for a 2026 buying guide. For SM6, the accurate statement is: one SR+ is official; the rest requires opening-data estimates and should be labeled that way.
Box Math at Current Pricing
| Metric | Value | What It Means |
|---|---|---|
| SST listed box price | ¥55,825 (~$362) | A useful sealed-price signal; check the product page for availability |
| Top card value | ~¥62,000 (May 2026) | Aggregator reading from May 2026; the October 7, 2026 asks are in the chase-card table |
| Original implied box MSRP | ¥4,500 + tax | 30 packs x ¥150 before tax |
| EV posture | Negative for most buyers | Open for experience, not expected profit |
Price Trends & Sealed Premium
SM6 launched when Japanese booster packs retailed at ¥150 + tax. A 30-pack box therefore implied ¥4,500 before tax, or roughly ¥4,860 with Japan’s 8% consumption tax at the time. A ¥55,825 (~$362) sealed-box listing means the box is no longer priced around pack value; it is priced around scarcity, Sun & Moon nostalgia, and sealed-display demand.
| Period / Signal | Price Context | Interpretation |
|---|---|---|
| March 2018 launch | ¥150 + tax per pack | Retail expansion-pack pricing |
| Implied 30-pack box retail | ¥4,500 before tax / ~¥4,860 tax-in | Baseline for sealed-premium comparison |
| October 7, 2026 SST listing | ¥55,825 (~$362) | Collector-grade sealed pricing, not opening-value pricing |
| Top chase card | Lady SR around ¥62,000 (May 2026) | Strong card ceiling (May 2026 reading) |
That gap is the core buying signal. A sealed SM6 box can still make sense as a collectible, but the price is already assuming scarcity. Singles buyers are not paying for sealed-box nostalgia, which is why Lady SR, Greninja GX, and Mysterious Treasure are usually cleaner targets.
Where to Buy SM6 Forbidden Light
SM6 is out of print, so availability moves in and out. When boxes return, prioritize sealed condition, reputable sourcing, and clear stock status. Avoid any listing that looks rewrapped, searched, or unusually cheap relative to the current market.
Buying Checklist
- Check stock status first – the SM6 box is listed at ¥55,825 (~$362); the product page shows current availability.
- Confirm sealed condition – old Sun & Moon boxes have enough value that condition matters.
- Do not chase one card by opening – buy Lady SR or Greninja GX directly if that is your target.
- Use tracked international shipping – older sealed boxes should not be shipped casually.
Bottom Line
Three things to remember about SM6 Forbidden Light in 2026:
- Lady SR is the market leader – the set is no longer best explained by Ultra Necrozma GX alone.
- The SR+ guarantee is real, but limited – one SR-or-better per box does not mean good odds at one specific chase card.
- Sealed boxes are priced as collectibles – at a listed ¥55,825 (~$362), the box-vs-singles decision heavily favors singles unless sealed scarcity is the point.
If you collect sealed Sun & Moon boxes, SM6 belongs on the watchlist. If you want the best cards, buy singles. If you want to open packs, treat the cost as entertainment, not an EV play.

Why did this article change so much?
The previous version used stale box pricing, outdated chase-card ordering, and unsupported EV-style claims. This refresh updates the article to match the current SST article standard: sourced specs, current market hierarchy, clear buying advice, and careful language around non-official pull rates.
