Punishing Gray Raven Simulation Shop Mousme: Memory and Simulation Score

Punishing Gray Raven Simulation Shop Mousme is the new six-star Memory option added to the Simulation Shop with the A Comet’s Afterglow update. You need Commandant Level 16 and Normal Story 1-12 completed before you can use that shop.

Unlike the version’s short-lived minigames, this addition is permanent. You spend Simulation Score on shop rewards, including Mousme and other useful items. Here is how to reach the shop and what to check before using the currency you have saved.

How to unlock Punishing Gray Raven Simulation Shop Mousme

Reach Commandant Level 16 and clear Normal Story 1-12. Both conditions are required for access to the Simulation Shop as described in Kuro’s version notes.

If you meet the level threshold but the shop is still inaccessible, check your Normal Story progression. The story requirement is 1-12, not the 1-8 needed for Leia’s Endeavorer’s Charm character trial.

Once you have access, open the shop and look for the available Memory items. The six-star Mousme Memory was added with the November 5, 2026 version update. The official announcement gives no separate December removal deadline for it.

Because the new item is in a permanent shop, there is no need to rush it simply because Dreamhouse Tycoon or Astral Obscura has an approaching end date. Those limited events are different activities with their own timers.

What Simulation Score is used for

Simulation Score is the currency used for rewards in the Simulation Shop. The new offering includes Mousme, the six-star Memory, and the Interstellar Wander decoration set.

Other available categories in the shop include selected six-star Memory Sets, Aura Basic Units, Aura Chips, character Affection Gifts, basic training materials and CUB training materials.

Punishing Gray Raven Simulation Shop Mousme does not mean every Memory in the game can be bought for one fixed price. Check the current shop item listing for availability, the required amount of Simulation Score and any stock restrictions before committing your currency.

Check the price, quantity available and any refresh rules on Mousme’s current shop listing. Those are the figures that matter when deciding whether to spend your Simulation Score.

Should you buy the Mousme Memory?

Mousme is a six-star Memory introduced alongside Leia: Fortunaster and the A Comet’s Afterglow version. The announcement confirms the Memory’s arrival in the Simulation Shop, but not the exact in-game set descriptions or the best combination for your roster.

Open the item preview and read the current two-piece and four-piece effects, if applicable, before spending Simulation Score. Compare those effects with the characters you are developing, rather than equating a new Memory release with a mandatory upgrade for every player.

If you are short of Simulation Score and also need basic character upgrades, compare the shop’s training and CUB materials with the value of the Memory for your specific team. It is entirely reasonable to save the currency until you know what you need.

The two-piece and four-piece effects matter more than the item’s six-star label. Read the set preview before redeeming, particularly if you are planning a build for Leia.

Can returning players get double Simulation Score?

Kuro’s updated Return Support system offers some eligible returning Commandants limited opportunities for double Simulation Score through return missions.

That is a returning-player benefit under particular conditions, not a permanent two-times Simulation Score reward for every account. If you are an active player, do not plan your purchases around a universal double-score event that the update never announced.

If you qualify for Return Support, check its mission screen for which attempts receive the bonus and how many remain. Look at your Return Support screen for the eligible attempts on your account.

Punishing Gray Raven Simulation Shop Mousme can be purchased with the currency the shop actually requests, and any returning-player bonus should be considered only when your own account shows the relevant benefit.

Shop checklist and common questions

First, clear Normal Story 1-12 and reach Level 16. Next, open Simulation Shop and inspect the Mousme Memory listing, its exact Simulation Score price and any available stock. Check other shop items before you spend.

Is Mousme a limited December event reward? The official version notes present it as a permanent Simulation Shop addition, not a prize that disappears with the December 16 side events. Is Simulation Score the same as research tickets? No, it is a separate shop currency.

Can you safely choose Mousme without checking its Memory effects? You can redeem an item when you have enough score, but whether it improves your preferred character depends on the effects shown in-game.

The practical choice is to review your current team and live shop preview, then spend Simulation Score where it helps most. There is no need to spend the moment the shop opens, especially when you are still deciding which Memory set suits your team.
