One Piece Card Game rarities explained: L, SR, SEC, SP and what a parallel is
Six marks cover almost everything in a Japanese One Piece booster, and the composition barely moves from set to set. The part that confuses people is not the marks — it is parallels, SP cards that carry the wrong number, and a Treasure Rare that only recently reached Japan.



In short
- A One Piece set is built from six tiers: L, C, UC, R, SR and SEC.
- A standard booster is 6 Leaders, 45 Commons, 30 Uncommons, 26 Rares, 10 Super Rares and 2 Secret Rares — 119 numbered cards.
- A parallel is not a new card: it is another print of the same number, which is why OP01-120 exists three times.
- SP cards carry numbers from earlier sets, not from the set you pulled them in.
- Treasure Rare reached the Japanese line in OP-16 (May 2026); before that it appeared only in English lists.
