⭐ Akane Kurokawa's "Happy Halloween" SSP is the most expensive card in Oshi no Ko Vol.3 (OSK/S133) on the Japanese singles market, and it isn't her only card among the set's priciest. This is the third 【推しの子】 booster set for Weiss Schwarz, built around the anime's third season.

About the Oshi no Ko Vol.3 set (OSK/S133)
It came out in Japan on 7 August 2026 and covers the anime's third season, which wrapped up in March 2026. There are six new illustrations, one per character: Ai, Aqua, Ruby, Kana Arima, Akane Kurokawa and MEM-cho.
Unlike Vol.2, this set has no SEC+. The most valuable pulls are the six SSPs.
Oshi no Ko Vol.1, Vol.2 and Vol.3 at a glance
- Vol.1 (OSK/S107): December 2023, 16 packs of 9 cards per box
- Vol.2 (OSK/S121): February 2025, 12 packs of 8 cards, with SEC+ and Rie Takahashi's AGR (Ai)
- Vol.3 (OSK/S133): August 2026, 10 packs of 8 cards, in the box format Bushiroad has used since April 2026
All three share the OSK title code, so you can play their cards in the same deck. If you'd rather start at the beginning, we also stock the Weiss Schwarz Oshi no Ko Vol.1 Booster Box.
