New setSeptember 20, 2026
Summer hologram released on September 25, 2026, and every card in it is now in the HoloHoard catalogue: 214 in all, 102 in the standard run and 112 in the parallel run. It is the first release in a new product line. An Extra Booster is not a numbered main set: the publisher describes it as a special booster line where each release is built around a single theme, and this one's theme is "That Summer Spent with Your Oshi". Two thirds of the standard run is reprints, which makes it an unusually direct way to pick up cards you missed.

The new cards lead with Oshi holomem for Tokino Sora, Houshou Marine and Hakui Koyori, and now that the cards are catalogued the colours are on record: Tokino Sora is Red, Houshou Marine is Blue, Hakui Koyori is Yellow. An Oshi holomem card is the one card that sits outside your deck for the whole game and carries the skills you spend holo Power on, so a new colour for a talent is a new way to build around them rather than a cosmetic variant. Each of the three takes the first number in the set, hEB01-001 to hEB01-003, and each exists in three treatments that share that number: the OSR in the standard run, and an OUR and a SEC in the parallel run. That is the whole top of this set's ladder, nine cards for three talents.
The standard run splits cleanly. Numbers hEB01-001 to hEB01-034 are new: the three Oshi cards, seven holomem cards apiece for the same three talents, and ten Support cards whose names carry the theme, among them Summer PC, Watermelon Splitting, Beach Ball, Splash Shooting and hololive Summer. The other 68 are the reprints the publisher promised, and they keep their original numbers, which is how this line has always handled them: a card numbered hBP01-021 in Summer hologram carries the same number and text as hBP01-021 in Blooming Radiance, with summer artwork, and is catalogued under the set you pulled it from. The reprints reach back across all five earlier boosters and eight start decks, so the gap you have been carrying since an older set may close here. The six cheer cards are here too, but only on the parallel side, in their Special and Special Cheer treatments. The three holomem Rare cards are the clearest example: all three are reprint numbers, one per headline talent, given the HR treatment with summer artwork.
The announcement said 102 standard types and 112 parallel types, and the catalogue holds exactly that, rarity by rarity. Read the table as two halves. The standard run is what a printed card list shows you. The parallel run is the same cards again in other treatments, sharing their numbers, and here it is heavier than the standard run: 76 of the 112 parallels are Super Rare, more than the 44 in Ayakashi Vermilion, and that is the largest set in the line. The three Double Rare holomem among the new numbers show how the halves stack, each with a Super Rare and an Ultra Rare parallel behind it, so one number is three different cards on the checklist.
| Half of the set | Cards | Rarities |
|---|---|---|
| Standard | 102 | OSR 3, RR 15, R 22, U 37, C 25 |
| Parallel | 112 | SEC 3, OUR 3, HR 3, UR 15, SY 6, SR 76, S 6 |
The set page carries all 214 cards with artwork, and the checklist page lists them by number so a half finished set is honest about what is actually missing. Because the parallels share card numbers with the standard run, each one is catalogued as its own card: marking the Common does not mark the Super Rare behind it. Values fill in as the market settles on a set that is three days old, so the price side of the page grows over the coming weeks without the checklist changing underneath it.
