What leaked

Leak chatter points to a second Heroines Edition extra booster, EB-05, arriving in October 2026, with Nico Robin named as the set's Leader. That would make it the follow-up to the original Heroines product, and the first Extra Booster since EB04 to carry a themed character focus rather than a general roster refresh.

Nothing is confirmed by Bandai, and nothing is priced. Our EB05 set page currently carries no box market, no expected value, and no EV ratio, because there is no product and no secondary market to measure. Anyone quoting you a sealed number today is quoting vibes.

The Robin read is currently negative

The most directly relevant ticker on the board is unhelpful for hype merchants. Nico Robin (ST01-008) sits at $24.99, down 29.9% on the week, which makes it one of the five worst performers in our seven-day table. Leader announcements do not usually rescue a starter deck print, and this one is bleeding into the news rather than off it.

That matters mainly as a sentiment check. Heroines-branded products historically trade on art demand rather than competitive utility, and a Leader reveal fourteen months out is a long way from a price catalyst.

What EB04 tells us about Extra Booster economics

The useful comparable is the current Extra Booster chase pool, which is running hot. Megalo (Alternate Art) EB04-018 is at $23.60, up 36.6% in seven days, and King (Alternate Art) EB04-031 is at $32.84, up 28.9%. Both sit inside this week's top five gainers.

Extra Boosters are small products with concentrated hit lists, which is exactly why their singles can move this violently in a week. It is also why sealed EV on them is volatile. For reference, here is where our tracked sealed EV currently sits across the main sets:

Set Box market (USD) Box EV (USD) EV ratio
OP17 410.62 655 1.59
OP15 253.35 202 0.80
OP14 264.28 189 0.71
OP11 632.38 437 0.69
PRB02 393.01 264 0.67

OP17 is the only tracked box above parity at a 1.59 ratio. Everything else in the top five is under 0.80. Full table lives on the EV page.

The wider tape

The week's other headlines are unrelated to the leak but set the mood. Jinbe (OP05-066) is up 58.1% to $31.25, and Sabo (004) Alternate Art is up 55.8% to $47.03. On the other side, Monkey.D.Luffy (079) Alternate Art fell 44.4% to $161.16, and Tony Tony.Chopper (Gift Collection 2023) dropped 30.5% to $183.83, both flagged at seaking severity in our whale feed.

Translation: the high end is choppy and the mid-tier alt art layer is where money is actually rotating. That is the layer a Heroines product sells into.

The Terminal take

A Leader reveal with no set list, no rarity structure, and a release window over a year out has no price implication we can measure, and the one Robin print we do track is down 29.9% into the news. The honest signal here is the EB04 tape: alt arts from the last Extra Booster gained 36.6% and 28.9% in a week, which tells you where demand for small, art-heavy products currently sits. Watch that pool, not the leak.
