Its 116 standard cards and 125 parallel versions include seven Oshi Ultra Rare cards, plus new alternate art for fan favorites like Mikkorone 24. Value is concentrated in the four signed SECs, which sell for well above the URs and OURs on this list.
15. Cecilia Immergreen (SR) hBP04-031
Cecilia, the flower-loving Ancient Automaton of hololive English -Justice-, gets an SR that works as a gentle entry point into the set. It is unsigned and the most budget-friendly card on this list, a low-cost way to add a -Justice- member to a collection.
14. Raora Panthera (SR) hBP04-019
Raora, the sharp-eyed artist of hololive English -Justice-, gets an SR in the same budget tier as Cecilia’s. It is unsigned, and a fitting pickup for a talent who illustrated a card herself in Ayakashi Vermilion.
13. Mikkorone 24 (SR) hBP02-084
Mikkorone 24 celebrates the 24-hour stream by Sakura Miko and Inugami Korone, and it arrives here with new alternate art. This unsigned SR keeps its original Quintet Spectrum number and is the priciest SR on this list.
12. Kaela Kovalskia (UR) hBP04-042
Kaela, the blacksmith adventurer of hololive Indonesia’s holoh3ro, gets a UR that represents her branch well in this set. It is unsigned and an affordable way to own a holoh3ro card.
11. Natsuiro Matsuri (UR) hBP04-082
Matsuri, the cheerleader of hololive’s 1st Generation, gets a UR that gives the veteran a place among the set’s top rarities. It is unsigned and the most affordable UR on this list.
10. Momosuzu Nene (UR) hBP04-086
Nene, the idol hopeful from another world in hololive’s 5th Generation, gets a UR that gives her generation a presence among the set’s premium pulls. It is unsigned and sits in the affordable tier alongside Kaela’s and Matsuri’s.
9. Shiori Novella (UR) hBP04-053
Shiori, the story-collecting Archiver of hololive English -Advent-, gets a UR that adds her generation to the set’s premium pulls. It is unsigned and a budget-friendly pick.
8. Koseki Bijou (UR) hBP04-066
Bijou, the gem formed from crystallized human emotion in hololive English -Advent-, gets a UR that pairs naturally with Shiori’s. It is unsigned and sits in the mid-range among the URs here.
7. Ichijou Ririka (OUR) hBP04-003 & Ichijou Ririka (UR) hBP04-037
Ririka, the entrepreneur of ReGLOSS in hololive DEV_IS, gets two cards in this set worth chasing. Neither is signed, since hot-stamped autographs are reserved for the set’s four SEC cards. The OUR is her Oshi holomem card, while the UR is her standard holomem card. The OUR carries a clear premium over the UR, which stays a mid-range pick.
6. Juufuutei Raden (OUR) hBP04-002 & Juufuutei Raden (UR) hBP04-025
Raden, the rakugo performer of ReGLOSS, also gets an Oshi OUR and a standard UR in this set. Neither card is signed. The OUR is her Oshi holomem card, while the UR is her standard holomem card. The UR is the priciest UR on this list, and the OUR commands a bigger premium still, having been sold out when checked in October 2026.
5. Anya Melfissa (OUR) hBP04-007
Anya, the sleepy Keris-turned-human of hololive Indonesia’s holoro, gets an Oshi OUR, the premium parallel of her Oshi holomem card. It is unsigned and the most accessible OUR on this list.
4. La+ Darknesss (SEC) hBP04-005
La+, the founder of Secret Society holoX, joins the game in this set, and her SEC is one of its four signature cards. It carries her own hot-stamped signature and is the most affordable of the set’s four SECs.
3. Yukihana Lamy (SEC) hBP04-004
Lamy, the snow noble of hololive’s 5th Generation, headlines the set as one of its four signature SECs. It carries her own hot-stamped signature and sits at the top of the price range for this set’s SECs.
2. Oozora Subaru (SEC) hBP04-006 & Oozora Subaru (UR) hBP04-072
Subaru, the cheerful MMA and e-sports team manager of hololive’s 2nd Generation, is the only talent on this list who pairs a signed SEC with a second card. Her SEC carries her own hot-stamped signature, while the UR is unsigned. The SEC is her Oshi holomem card and the UR is a standard holomem card. The SEC is a premium pick, while the UR is a budget-friendly way to own her.
1. Hakui Koyori (SEC) hBP04-001
Koyori, the self-proclaimed brain of Secret Society holoX, anchors the set’s theme alongside La+, and her SEC is its headline card. It carries her own hot-stamped signature and sits at the top of the price range for the set.
Curious Universe is a strong fourth booster that balances a clear chase tier with plenty of accessible pulls. Its four hot-stamped SECs and seven Oshi OURs give collectors real targets, while the SR and UR tier stays affordable for casual collectors. Fresh additions like holoX’s arrival and the alternate art for Mikkorone 24 keep the checklist from feeling like a rehash of earlier sets. Overall, it rewards both budget collectors and signature hunters, which makes it one of the easier sets to recommend.
