Weiss Schwarz is bringing Kaiju No. 8 to the stage on January 29, 2027, with the Trial Deck and Booster Pack releasing the same day. This is the Weiss Schwarz trading card game adaptation specifically, built around the Japan Defense Force's battles from the hit anime.
That's worth flagging up front for anyone who's followed EVORETRO's earlier Kaiju No. 8 coverage: this release is the card game, not the Nendoroid, Pop Up Parade, or Ichiban Kuji figure lines already covered separately. The two product categories don't overlap in contents or price point.
Both products share the KJ8/ card number prefix, so Trial Deck and Booster Pack cards combine into one constructed build. Six voice cast members get hot-stamped signature cards across the two products, a notably large signature roster for a single Weiss Schwarz release.
This guide covers exactly what's in the Trial Deck and Booster Pack, which cast signatures appear where, and how to keep hot-stamped and embossed pulls in shape from day one.
Each Trial Deck carries 50 cards drawn from a pool of 20 base types plus 22 parallels, shipping four decks per display and eight displays per carton. Every deck guarantees two shiny parallel cards plus one of either an embossed Triple Rare (19 types) or a hot-stamped Special card (2 types).
The Trial Deck specifically features hot-stamped sign cards from Masaya Fukunishi (as Kaiju No. 8) and Fairouz Ai (as Kikoru Shinomiya), with a Rules Sheet, Playmat, and Deck Manual rounding out a complete starting package.
The Booster Pack goes considerably deeper, with 100 base card types plus 121 parallels spanning Common up through Super Rare, Triple Rare, Special, Super Special, Secret, and two Serial Rare slots — the highest rarity tier in the set. Twelve Climax Rare cards round out the ladder.
Packs hold 8 cards each, 10 packs per display, 12 displays per carton. The Booster Pack expands the hot-stamped signature roster to all six featured cast members: Masaya Fukunishi, Wataru Kato, Fairouz Ai, Asami Seto, Kengo Kawanishi, and Koki Uchiyama, alongside 12 newly-drawn illustrations exclusive to this product.
Landing hot-stamped signatures from six separate cast members in one set is a larger signature roster than most single-anime Weiss Schwarz releases carry. The Trial Deck covers two of those six, while the Booster Pack is where the full six-person roster becomes available.
Collectors specifically chasing a complete cast-signature set need both products — the Trial Deck alone only gets two of the six names, and the other four exist exclusively in Booster Pack pulls.
Because both products share the KJ8/ prefix, a Trial Deck purchase gives a genuinely playable 50-card foundation that Booster Pack pulls can slot directly into without any compatibility concerns. That's standard Weiss Schwarz structure, confirmed here explicitly for the Kaiju No. 8 release.
New players are better served starting with the Trial Deck's structured, ready-to-play 50 cards before layering in booster pulls, rather than trying to assemble a first deck from loose boosters alone.
EVORETRO has previously covered Kaiju No. 8 figure collecting — Nendoroid and Pop Up Parade protection, and the Ichiban Kuji prize lineup — but those are a completely separate product category from this Weiss Schwarz release. Figures and trading cards don't share packaging, price point, or collecting habits.
Anyone searching for Kaiju No. 8 card game information specifically should bookmark this release rather than the earlier figure-focused guides, since the storage and protection needs for a 50-card deck look nothing like what a Nendoroid display needs.
With guaranteed shiny parallels in every Trial Deck and a Booster Pack rarity ladder running all the way up to Serial Rare and Secret, this release produces a meaningful volume of foil and hot-stamped cards fast. Sleeving pulls immediately protects embossed and foil surfaces from the scuffing that comes with loose handling.
A dedicated bulk storage option also matters here given how deep the Booster Pack's card pool runs — 100 base types plus 121 parallels adds up quickly for anyone opening more than a single display.
Both release January 29, 2027.
Six, though only two appear in the Trial Deck specifically.
No, this is the separate Weiss Schwarz trading card release.
50 cards, with two guaranteed shiny parallels plus one embossed or hot-stamped pull.
With hot-stamped signatures split across both products, sleeving every pull the moment it's opened keeps the chase intact long-term. EVORETRO's perfect fit sleeves protect foil and hot-stamped surfaces without adding bulk to a Kaiju No. 8 constructed deck.
