- Costume ×1
274 real shop items pulled straight from the game's data, split across 4 counters: Costumes, Packs, Mission Pass, Jewel — every entry translates the exact name, price and reward, nothing guessed.
The Gakumas shop mixes two completely different currencies (in-game Jewel vs. real-money JPY) in the same interface, making it easy to tap the wrong thing. This page lists all 274 items with the correct currency + amount + purchase limit + real reward, so you know what's worth buying with Jewel you earned for free before considering a real-money top-up. Filter by counter (Costumes/Packs/Pass/Jewel), type into the search box to filter by item name or character.

No item matches this filter
Each card is ONE item — the price shows exactly the currency the raw data records: Jewel (in-game currency, Costume/Pack counters) or JPY (real money via the app store, Mission Pass/Jewel counters). The "Time-limited" tag is inferred from the item's own name (a time/date marker or "limited"-type wording); expired items are still listed for reference.
4 counters: Costumes (160 items — just 20 base designs resold across many characters), Packs (59 items — a mix of recurring farming bundles and time-limited anniversary packs), Mission Pass (28 monthly releases) and Jewel (27 top-up bundles).
A purchase limit of 0 in the raw data means unlimited purchases. Rewards show every real line from the data — the Pack counter usually pays several material lines at once, the Costume counter is almost always exactly 1 line.
Source: vertesan/gakumasu-diff master data (fetched 05/08/2026). 274 real items (ShopItem.yaml, empty webstore counter excluded), JPY price joined from ShopProduct.yaml.
The publisher's own data splits the shop into 5 counters (Shop.yaml), but the "external checkout" (webstore) counter has no items listed in the publisher's data, so this page only shows the 4 counters that actually have stock: Costumes (160 items — 200-700 Jewel each depending on type), Packs (59 items — a mix of farming/anniversary bundles, Jewel price ranging roughly 200-5,000 depending on the pack), Mission Pass (28 monthly releases, bought with JPY) and Jewel (27 top-up bundles, bought with JPY through the app's payment gate).
An easy point to misread: the Jewel and Mission Pass counters live "inside the game shop" but they themselves ARE the real-money transaction — neither has any Jewel price in the data (the Jewel-price field is 0 for both), the real price lives in the ShopProduct data (denominated in JPY, joined via product ID). By contrast, the Costume and Pack counters always have a clear Jewel price — this is stuff you EARN inside the game (through missions/achievements/producing) and can spend without ever topping up real money.
The 160 costume items in the shop actually boil down to just 20 distinct base designs (e.g. Child Smock, Sailor Swimsuit, Hatsuboshi Academy Gym Uniform...) — each design gets resold separately per character (the character name always sits in parentheses after the design name, e.g. "Sailor Swimsuit (Hanami Saki)"). This is a real count taken straight from the item names in the data — the page isn't missing stock, the publisher genuinely reuses designs across many characters to save art production.
Some items carry a "-resale" or "-revival" suffix in their ID — meaning that item was sold before, pulled, and later put back on sale (not a brand-new design). The Costume counter's reward is almost always exactly 1 line (the costume/accessory itself) — unlike the Pack counter, which usually pays out several material lines at once.
The page clearly flags each pack as "time-limited" or not, inferred straight from the original text (a 【】 bracket stating hours/days, or "limited"-type wording in the name) — never guessed. Packs WITHOUT this flag are usually RECURRING bundles (refreshing daily/weekly/monthly, e.g. the Daily AP Pack, Weekly/Monthly Training Pack) — purchasable again and again on a cycle, no risk of missing out.
Packs WITH the time-limited flag (e.g. the per-character "Produce Idol Piece Pack" series, or event-anniversary packs) only appeared once in a specific window and then vanished — this data comes from a single data pull, so packs whose window has already passed are still listed here as reference material (not currently on sale). A purchase limit (purchase_limit) of 0 means unlimited purchases in the raw data — most common on the Jewel counter.
The raw data does record epoch-format start/end timestamps, but most items CURRENTLY on sale have no real end timestamp (a special value that effectively means "until the publisher manually pulls it"), while EXPIRED items' timestamps are already in the past and no longer practically useful (you can't buy it again no matter what date is shown). The page only uses a simple time-limited yes/no flag inferred from the item's own NAME — the one thing that stays accurate no matter when you view this page, avoiding a printed date that might already be out of sync with the live game.
The page shows only the raw JPY price straight from the publisher's data (ShopProduct.yaml) — it does not auto-convert to VND/USD, because exchange rates change daily and baking a fixed conversion into static data would quickly go stale and could mislead you about the real price at checkout. To know the price in your own currency, take the exact JPY figure shown here and convert it at the current rate yourself, or check the final price the app store shows you at the moment you tap buy (the store may add regional tax/fees on top).
The page only attaches a character name when it can EXACTLY match the Japanese name in parentheses against one of the 14 confirmed base idols in the game's data — if the name in parentheses doesn't match (e.g. a shared-accessory item, or a newer character not yet in the name-lookup table) the page leaves it blank rather than guessing, to avoid attributing a costume to the wrong person.
