Crimson Haze (SV5a, 2024): English Equivalent and Import Guide
By Dexhaul Team · October 9, 2026 · 6 min read
Crimson Haze landed in Japan on March 22, 2024 as set SV5a. Its English equivalent arrived 63 days later as Twilight Masquerade on May 24, 2024, making it one of the shorter JP-to-EN windows in the Scarlet and Violet era.
The gap matters most to import buyers: SV5a boxes were two months old when Twilight Masquerade launched. Here is the full mapping, format differences, and the JP-vs-EN decision framework.
Set mapping: SV5a to English
Crimson Haze is one of two Japanese sets that fed into a single English release. SV5a and SV6 Mask of Change (April 26, 2024) both became Twilight Masquerade in English on the same day.
| JP Set | Code | JP Release | EN Set | EN Release | JP-to-EN Gap |
|---|---|---|---|---|---|
| Crimson Haze | SV5a | March 22, 2024 | Twilight Masquerade | May 24, 2024 | 63 days |
| Mask of Change | SV6 | April 26, 2024 | Twilight Masquerade | May 24, 2024 | 28 days |
This two-to-one consolidation is the most important fact for import buyers. Opening one English box pulls from the combined card pool of both JP sets. Opening SV5a pulls only from SV5a.
For the broader Scarlet and Violet era JP-to-EN mapping, the full SV era guide covers every set pair from SV1S through the Mega Evolution era.

What changes in the box
The physical box experience differs significantly. SV5a uses the standard Japanese format: 30 packs per box, five cards per pack. Twilight Masquerade uses the English format: 36 packs per box, ten cards per pack.
| SV5a Crimson Haze (JP) | Twilight Masquerade (EN) | |
|---|---|---|
| Packs per booster box | 30 | 36 |
| Cards per pack | 5 | 10 |
| Total cards per box | 150 | 360 |
| Base set size | 96 cards | 162 cards |
| Promo cards (standard box) | None | None (ETB includes Ogerpon foil) |
| EN MSRP per pack | n/a | $4.99 |
SV5a has 96 base cards. Twilight Masquerade has 162, with above-ceiling rarities bringing the total to 226. The extra English cards come primarily from SV6 Mask of Change, which ran parallel to SV5a in Japan.
Featured cards in both sets
Crimson Haze centers on the Teal Mask DLC storyline: Ogerpon's four mask forms and the "Loyal Three." About 90 of SV5a's 96 base cards debuted in Twilight Masquerade, per Limitless TCG's JP/EN crosswalk. The remaining cards appeared in other English releases.

Japanese or English Four questions to settle it
Price per pack
SV5a booster boxes are observed at $97.00 to $137.00 USD from independent importers as of October 2026, putting the per-pack floor at roughly $3.23 per pack. The English Twilight Masquerade booster box runs $235.00 to $390.00 for 36 packs, a floor of $6.53 per pack. On raw per-pack cost, Japanese is cheaper.
Per card at floor prices, both versions come to about $0.65 per card. The cost-per-card is nearly identical; the Japanese version delivers it in smaller batches.
Play legality
Japanese cards cannot be used in English-format sanctioned play. Tournament rules require all cards to match the event's official language format, covering League Challenges, Regionals, and Nationals. Competitive players should buy English Twilight Masquerade for legal play.
Language and artwork
SV5a artwork and card text are in Japanese. The foil treatments on JP ex cards use the same printing standard as English, and the artwork is identical across both languages.
Some collectors prefer JP for the cleaner layout and the absence of English card text. The Japanese SV5a booster box also comes without a promo, so JP buyers get no language-exclusive promo card in this set.
Grading
PSA, BGS, and CGC all grade Japanese Pokémon cards.
The grading criteria and process are identical to English. Japanese SV5a cards are worth grading if the card has collector demand, but the secondary market for graded JP ex cards is smaller than for their English Twilight Masquerade counterparts. Buyers grading for resale should factor in that narrower buyer pool.
The Twilight Masquerade consolidation
This is the detail that catches most import buyers off guard. Twilight Masquerade absorbed both SV5a and SV6 Mask of Change into one English release. Japan ran these 35 days apart; English merged them into a single set.
In practice, this means SV5a completionists face a different challenge in each language. A Japanese SV5a set run ends at card 096/096.
An English Twilight Masquerade set run goes to 162 base cards (plus rarities to 226 total), because it includes SV6 content as well. Completing the JP set is a smaller, more focused task. The English set covers two JP sets' content from one product.
For buyers who want the Teal Mask Ogerpon content in English without the full set investment, the Twilight Masquerade Booster Bundle (6 packs, no accessories) is the entry point at around $75.00, observed October 2026. The ETB is the better value if you also need sleeves and accessories.
A similar import question runs through the broader SV era. The Super Electric Breaker vs Surging Sparks guide covers the same JP/EN decision framework for SV8 and its English equivalent, published October 2026.
