Memories Memory

21 real Memories present in Gakuen Idolmaster's data, plus 236 memory-skill effects decoded from the source code — nothing guessed.

What this page solves

A Memory is what you keep after a Produce run, carrying stats and skills into Contest mode — but the game has no single screen listing all 21 Memories at once. This page gathers everything in one place: 21 real Memories with their required Grade and skills, plus a table of 236 decoded memory-skill effects (merged from 575 raw records), how to exchange Memories with tickets by Grade, and skill-reroll pricing.

Exchange Memories with Tickets

After every Produce run, you receive a Memory exchange ticket matching the Plan you played — the number of tickets scales with your result Grade.

3 ticket types by Plan: Plan 1 · Plan 2 · Plan 3

Rerolling Skills

To change the skills on a Memory you already own, you pay materials to reroll — the cost rises with how many slots you lock to keep (rows) and how many consecutive rerolls you do in one sitting (columns).

Source: vertesan/gakumasu-diff master data (fetched 05/08/2026) — MemoryGift.yaml + MemoryAbility.yaml + MemoryExchangeItem/MemoryExchangeItemQuantity.yaml + ResearchMemoryRerollCost.yaml. Skill effects are derived from a fixed token dictionary (real trigger/context/effect in the source code), nothing guessed.

Quick guide

In Gakuen Idolmaster, a "Memory" is what you keep AFTER a Produce run ends — it packages part of that run's Vocal/Dance/Visual stats plus a handful of skills, so you can carry them into Contest mode (asynchronous battles against other Producers) without replaying from scratch. The problem is the game has no single place listing exactly what each Memory grants and when it triggers — that information is scattered across different confirmation screens. This page gathers every Memory present in the game data, along with an effect-category table and how exchange/reroll works, translated straight from the source data.

The 3 Memory Groups Present in the Game Data

The data currently holds 21 Memories, which naturally split into 3 groups by their own source IDs (not an invented split). The "First Live" group (3 sets, Grade F) is the default memory tied to the first/failed Produce run of 3 starter idols — it carries just one small stat-boost skill, so a brand-new player has something to bring into Contest right away. The "Beginner Support" group (6 sets, Grade F) is a straight gift for new accounts, split evenly across the 3 Produce Plans, two sets per Plan tied to two different idols. The "H.I.F Support" group (10 sets, Grade SSS) is a premium reward tied to the Hatsuboshi Idol Festival event, carrying much higher stats (200-400 per stat) and a tier-2 stat-boost skill stronger than the beginner group's tier-1.

Beyond these 3 common groups there are 2 special Memories (kcna/shro, Grade D) tied to one specific idol each, unlocked from a time-limited campaign (their IDs carry the date stamp 20251116) — proof the game keeps adding new Memories tied to events, not a fixed permanent list.

How to Read the Effect Line: When It Triggers, What It Does

The source data for each memory skill has NO ready-made name or description for players — only an internal code that encodes 3 parts: the TRIGGER timing (Produce start, end of a lesson, start of a Contest audition...), the CONTEXT it applies in (a Vocal/Dance/Visual lesson, restricted to a specific Plan), and the specific EFFECT (add to a stat, recover Stamina, gain Block...). Every effect line on this page is assembled from exactly those 3 parts — nothing added or guessed beyond the source code. The accompanying "Power" number is the game's internal "evaluation" value used to rank relative strength among skills of the same kind — higher means stronger.

The single largest effect group across all 575 raw records (105 of 340 unique codes) is a "duration scales with turns" skill exclusive to the H.I.F memory line in Contest battles — an internal lookup table with many intensity tiers. This page collapses it into one representative line instead of listing every tier to avoid meaningless repetition.

Frequently asked questions

Why do many effect lines look identical?

Because that is exactly what the source data shows — the game reuses the same effect template (e.g. "add to Vocal/Dance/Visual at Produce start") across several different Memories, differing only in strength ("evaluation") or the idol attached. This page does not artificially vary the wording to make each line look different — accurate repetition beats invented variety.

Why do H.I.F Memories always require Grade SSS?

All 10 H.I.F Memory sets in the data list Grade SSS — this is the source figure, not a threshold this page invented. It is likely the Produce-result grade you need to reach to unlock that event's reward, but the static data has no extra line explaining the reasoning — this page only shows the exact figure the publisher lists, nothing further inferred.

How does exchanging Memories with tickets and rerolling skills work?

The data shows 2 separate mechanics. (1) Memory exchange: each Produce Plan 1/2/3 has its own exchange ticket, and the number of tickets earned after a Produce run scales with your result Grade — from 1 ticket at Grade F/E/D up to 5 tickets at Grade SSS/SSS+ (full table in the "Exchange Memories" section on this page). (2) Rerolling an existing Memory's skills: the cost scales along 2 axes — the more skill slots you lock to keep unchanged (lockCount 0-4) and the more consecutive rerolls in one sitting (rerollCount 1-11), the higher the cost per roll, ranging from 50 to 730 material units.
