Anya carries this set. The Matching Keychain Anya secret rare sits at about $200 in our July 2026 snapshot, the top five is mostly her and Yor, and the boxes those cards come from rip at roughly half their sticker price. That's the whole review; the rest is detail worth knowing before you spend money on it.
The English SPY x FAMILY Weiss Schwarz set released January 26, 2024, riding one of the biggest anime licenses of the decade. Weiss is Bushiroad's crossover engine — every hot anime eventually gets a set — and the formula is consistent: cheap playable commons, foil chase tiers, and premium SP cards bearing printed signatures of the Japanese voice cast. How each set performs comes down to one question: which characters do people love enough to pay for?
The chase: the Forger family tax
From the snapshot:
- Matching Keychain, Anya (SEC) — about $200
- "Thorn Princess", Yor (SP) — about $175
- Telepath Girl, Anya (SP) — about $138
- Cool Agent, "Twilight" (SP) — about $120
- "Nightfall", Fiona Frost (SP) — about $96
- Kind Smile, Loid (SEC) — about $85
Two Anya cards, one Yor at $175, and Loid — the actual protagonist — bringing up the rear at $85. Character demand concentration is the defining feature of anime license sets: the market doesn't buy the show, it buys specific faces. That's chase card economics with a fandom twist — the set's value hangs on a couple of characters staying beloved, and everything outside the top eight fades toward bulk fast.
Pull rates: estimate generously, expect less
The calculator's generic Weiss model for the 9-card pack's hit slot: about 12% Triple Rare, 6% Special Rare, 2% Super-Special. Weiss pull rates vary more by set and franchise than any game we track, and Bushiroad publishes nothing, so treat these as loose community estimates. In practice, a 16-pack box typically yields foils and a triple rare or two; the SP-tier signature cards are the rare event, not the routine. The typical box outcome is far below the box's average EV, because the average leans on hits most boxes don't contain.
The box math, and one oddity
| Product | Price | EV | Margin |
|---|---|---|---|
| Booster Pack (loose) | $3.43 | $2.34 | -33% |
| Booster Box (16 packs) | $71.79 | $37.40 | -49% |
Notice the loose packs: $3.43 each, versus about $4.49 per pack inside a sealed box. Sealed-box buyers are paying a premium for the intact box — which means if you're ripping for fun, loose packs are the strictly better deal here, a full 16 percentage points less bad. (Usual caveat on loose packs: buy from sellers you trust, since opened-and-resealed product exists in every hot game.) Either way the direction is the same — you're paying $72 for $37 of expected cards. Run the live numbers for this set before deciding.
How anime license sets age
This is the part most buyers skip. License sets live on the licensing calendar: value spikes with new seasons and movies, then decays as the fandom's attention moves on. There's no rotation forcing player demand and no evergreen game economy underneath — just the show's cultural moment. The historical pattern across Weiss sets is that top-character SPs hold surprisingly well (the Anya buyers aren't leaving) while the mid-tier chase and everything below it slides toward bulk. If you're holding sealed SPY x FAMILY, you're betting the franchise stays hot through its next media cycle — a real possibility with more anime on the way, but a bet on a studio's release schedule, not on cardboard scarcity. Contrast that with hololive Weiss, where hand-signed cards and perpetual VTuber fandom give the chase a durability this set doesn't have.
Verdict: buy the Anya, skip the box
Straight call: buy singles. The $200 Matching Keychain Anya costs less than three boxes, and three boxes gets you nowhere near even odds of pulling it. Fans who want the ripping experience should buy loose packs, not sealed boxes — cheaper per pack, same lottery. And sealed-and-hold is the weakest play here: -49% at the rip, reprint risk if the license stays hot, fading demand if it doesn't. The cards are charming. The math is not.
