Weiss Schwarz Oshi No Ko has two English booster volumes so far: Vol.1 launched on September 20, 2024, and Vol.2 followed on March 27, 2026. Vol.1 draws on the anime’s first season, from Ai’s idol days to the new B-Komachi, and its headline cards are signed “B-KOMACHI” SSPs of Ai, Ruby, Kana and MEMcho.

Vol.2 moves on to the second season’s Tokyo Blade stage play arc, with cards like Aqua as Touki, and adds six new illustrations of the cast in everyday and holiday scenes. Both volumes are packed with signed chase cards, and below are the 10 most valuable, plus the special cards that arrived with Vol.2.
10. Hectic Filming Schedule, MEMcho (SEC+) & “B-KOMACHI” MEMcho (SSP)


MEMcho, the YouTuber who joined the new B-Komachi, ranks 5th on Minna no Ranking’s ongoing Oshi no Ko fan vote of more than 11,000 voters. The “B-KOMACHI” SSP carries the hot-stamped signature of her voice actor, Rumi Okubo, and the Japanese print of the SEC+ features MEMcho’s own character signature. The SSP comes from Vol.1 packs and the SEC+ from Vol.2, where it’s one of only two SEC+ cards. Bushiroad describes SEC+ cards as packed in extremely rarely, which makes this SEC+ one of the toughest pulls in either volume.
9. Putting Her Feelings Into Her Acting, Akane Kurokawa (SSP) & Pride as an Actress, Akane Kurokawa (SP)


Akane has more than 6,500 favorites on MyAnimeList, and her scene playing Ai on the reality show won Best in the Variety Division of Weekly Young Jump’s 2022 “Oshidemy Awards” fan vote. Both cards carry the hot-stamped signature of her voice actor, Manaka Iwami. The SSP comes from Vol.1, while the SP comes from Vol.2, where Akane and Kana each got a “Pride as an Actress” card. Each volume has only six SSPs and six SPs, so owning both puts two of Akane’s rarest signed cards in your binder.
8. Coffee in One Hand, Aqua (SSP)

Aqua ranks 3rd on Minna no Ranking’s Oshi no Ko fan vote, behind only his mother Ai and his twin sister Ruby. The Japanese print of this Vol.2 SSP carries the hot-stamped signature of his voice actor, Takeo Otsuka.
7. Intense Emotional Acting, Aqua -Touki- (SP)

Aqua’s climactic stage scene with Akane won Best in the Acting Division of Weekly Young Jump’s “Oshidemy Awards,” and this card shows him as Touki, his role in the Tokyo Blade stage play. It carries the hot-stamped signature of Takeo Otsuka, Aqua’s voice actor.
6. Pride as an Actress, Kana Arima (SP)

Kana is the most favorited member of the main cast on MyAnimeList, with more than 9,300 favorites. This Vol.2 SP carries the hot-stamped signature of her voice actor, Megumi Han.
5. “B-KOMACHI” Kana Arima (SSP)

Kana’s big on-stage moment with B-Komachi won Best in the Idol Division of Weekly Young Jump’s “Oshidemy Awards.” Her Vol.1 SSP carries the hot-stamped signature of Megumi Han, Kana’s voice actor.
4. “B-KOMACHI” Ruby (SSP)

Ruby ranks 2nd on Minna no Ranking’s Oshi no Ko fan vote, second only to her mother, Ai. This Vol.1 SSP carries the hot-stamped signature of her voice actor, Yurie Igoma.
3. To a Shining Stage, Ruby (SP)

Ruby’s smile on stage with B-Komachi earned an Excellence prize in the Idol Division of Weekly Young Jump’s “Oshidemy Awards.” This Vol.1 SP carries the hot-stamped signature of Yurie Igoma, Ruby’s voice actor.
2. “B-KOMACHI” Ai (SSP)

Ai has more than 8,000 favorites on MyAnimeList, second only to Kana among the main cast. This Vol.1 SSP carries the hot-stamped signature of her voice actor, Rie Takahashi.
1. Meetup on Christmas Eve, Ai (SSP)

Ai tops Minna no Ranking’s ongoing Oshi no Ko fan vote with 92.5 points from more than 11,000 voters, ahead of every other character in the series. The Japanese print of this Vol.2 SSP carries the hot-stamped signature of Rie Takahashi, Ai’s voice actor.
Special Cards from Weiss Schwarz Oshi No Ko Vol.2
Prelude to Dusk, Akane Kurokawa (PR+) & Prelude to Dusk, Kana Arima (PR+)


Kana and Akane, the rival actresses at the heart of the Tokyo Blade arc, finished 1st and 2nd in Dengeki Online’s 2024 reader poll. In Japan, the PR+ versions of both cards were signed winner prizes, which is what sets them apart from the regular promo prints. In English they’re tournament prizes rather than pack pulls: at Bushiroad’s Meister Cup for Vol.2 in April 2026, every player got the regular Akane promo, the top four got a Kana promo, and only the champion took home the Kana PR+. That champion-only distribution makes the PR+ versions some of the hardest Oshi no Ko cards to find.
Becoming a Popular Streamer, MEMcho (SP)

MEMcho, the popular YouTuber who joined the new B-Komachi, has more than 1,000 favorites on MyAnimeList, and this card celebrates her streaming career. Like every Vol.2 SP, it carries the hot-stamped signature of her voice actor, Rumi Okubo.
Guided Twin Stars, Aqua & Ruby (SEC+)

Aqua and Ruby both made the top five in Dengeki Online’s 2024 reader poll, and this card puts the Hoshino twins together on one of Vol.2’s only two SEC+ cards. Its Japanese print features the twins’ own character signatures rather than their voice actors’.

Before you buy, remember that these signatures are hot-stamped copies rather than hand-signed autographs, so be wary of listings that call them “autographed.” Check whether a listing is the English or Japanese printing, since both volumes came out in Japan first, in December 2023 and February 2025. Bushiroad’s product pages don’t list pull rates for the signed cards, so buying singles is the most reliable way to land a specific character. For the scarce SEC+ and PR+ cards, ask for clear photos of the actual card, and sleeve and top-load anything you buy right away.
