Hololive OFFICIAL CARD GAME — Curious Universe (hBP04) English Booster Box

The hololive OFFICIAL CARD GAME Booster Pack Curious Universe (set code: hBP04) is the fourth booster set for the hololive OFFICIAL CARD GAME, published by Bushiroad Creative. The Japanese edition released on June 20, 2025, with the English edition following on February 20, 2026. This is the English language edition.

Curious Universe introduces Oozora Subaru and Yukihana Lamy as the headline Oshi Holomem cards alongside five additional new Oshi Holomem debuts — La+ Darknesss, Hakui Koyori, Ichijou Ririka, Juufuutei Raden, and Anya Melfissa. Amane Kanata also returns with a new card design. Two EN-exclusive Spot Holomem cards — Elizabeth Rose Bloodflame and Gigi Murin — are included as colorless cards unique to the English edition, making the English version a distinct collector item rather than a simple translation of the Japanese release. Several talents who appeared in earlier sets also return in Curious Universe with brand-new card designs, expanding the playable options for existing deck archetypes built around those members.

The full set contains 108 standard card types plus 117 parallel card types across the following rarities. Standard: OSR (7 types), RR (12 types), R (18 types), U (35 types), C (46 types). Parallel: SEC (4 types), OUR (7 types), UR (12 types), SY (6 types), SR (31 types), S (57 types). Each pack contains 8 cards out of the combined 225 card types available across the set.

The full Oshi Holomem roster featured in this set: Oozora Subaru, Yukihana Lamy, La+ Darknesss, Hakui Koyori, Ichijou Ririka, Juufuutei Raden, Anya Melfissa, and Amane Kanata. Holomem cards featured across the full set include: Shirakami Fubuki, Natsuiro Matsuri, Murasaki Shion, Oozora Subaru, Ookami Mio, Houshou Marine, Yukihana Lamy, La+ Darknesss, Hakui Koyori, Ichijou Ririka, Juufuutei Raden, Anya Melfissa, Amane Kanata, Elizabeth Rose Bloodflame, and Gigi Murin.

Note: a Start Deck is required to play — this booster box is not a standalone playable product on its own. Compatible Start Decks include the White Todoroki, Green Kazama Iroha, and Yellow Shiranui Flare decks released alongside Elite Spark in December 2025.

Box contents: 12 booster packs per box. 8 cards per pack. 96 total cards per box. Language: English. Publisher: Bushiroad Creative. Condition: Factory sealed.

Ideal for hololive fans collecting Oozora Subaru, Yukihana Lamy, La+ Darknesss, Anya Melfissa, and the full Curious Universe talent roster, HOCG players expanding their decks with the fourth booster set, and collectors who want the EN-exclusive Elizabeth Rose Bloodflame and Gigi Murin Spot Holomem cards not found in the Japanese version.
