Right now: the best rip in BOCCHI THE ROCK! is the Booster Box (16 packs) at $113.95 against $307.72 of expected pulls — a +130% margin after ~15% selling fees, and a 28% chance it actually pays for itself. Figures refresh every two hours.
Bocchi the Rock (June 14, 2024) is a standard Weiss Schwarz booster: nine cards per pack, sixteen packs per box, one Rare-or-better slot and one foil hit slot. Its sealed-market character is that of a single-monster set — a broad, cheaply priced singles pool sitting under one card that dominates every box's expected value, and a booster box that has modeled strongly positive because of it.
The hit slot pays a foil Rare over half the time, a Super Rare a quarter, a Triple Rare or better about one pack in five; Special Rares land near 1 in 17, Super-Specials around 1 in 50. That's where True Face of Guitarhero, Hitori Gotoh (SSP) lives. Performance of Her Dreams (RRR) and the Kessoku Band Rares for Nijika and Kita are the secondary hits.
Only one product is priced — the 16-pack booster box — so loose packs don't appear and the box row is the whole story. Read the fee-adjusted margin next to the probability of profiting: a high average driven by one SSP hides a lot of boxes that never see it.

FAQ
How many packs are in a Bocchi the Rock booster box?
Sixteen packs of nine cards each, the standard Weiss Schwarz box configuration. It's the only sealed product priced for this set at the moment — loose packs aren't listed, so the live table shows the box row alone.
What are the chase cards in Bocchi the Rock Weiss Schwarz?
True Face of Guitarhero, Hitori Gotoh in its Super Special Rare form is the headline, priced far above anything else in the set. Performance of Her Dreams (RRR), the Over-Frame Rare My Own Color, and the Kessoku Band Rares for Nijika and Kita make up the second tier.
Are Bocchi the Rock pull rates official?
No. Bushiroad doesn't publish Weiss Schwarz pull rates, so the slot odds here are community estimates applied to a standard nine-card pack. Signed and serial-numbered variants are excluded from the model entirely.
