Shigaku Surname: Rerolls and Codes Explained (September 2026)

Quick answer

Surnames in Shigaku are a customization attribute changed with rerolls — the same currency the game uses for other appearance and ability changes. Codes are how you stock up on rerolls.

• Pocket Tactics frames it plainly: “Codes get you rerolls, which are what you need for basically anything in this game. New hair? Rerolls. New surname? Rerolls.”
• GameRant describes the same system from the starting-roll side: “Every active code drops rerolls, so you can swap your face and kit instead of living with the first roll the game handed you.” It adds that “Twenty-five rerolls is a big starter pile. One promo code can cover a few face changes and a couple of ability rolls.”
• What a surname roll can actually produce isn't documented — no surname names, rarity tiers, or effects are published for the current game.

Is there a verified Shigaku surname list?

Not one that can be published yet. As of September 26, 2026 — the most recent date on the code list below — no surname names are documented in Shigaku, and nothing attaches rarity tiers, odds, percentages, or gameplay, stat, or clan effects to surnames. Surnames are known to be changeable because rerolls are described as covering them, but the mechanics beyond that are open questions: which surname outcomes a roll can produce, where the surname reroll sits in the UI, whether surnames roll separately from hair or face, and what a single roll yields are all undocumented. Whether rerolls are one shared pool across all customization attributes or split into separate types isn't stated either. If a customization update lands, surname entries and any rarity or effect data are worth rechecking.

Reroll codes reported for September 2026

Rerolls come from redeeming Shigaku codes. The fullest current list comes from Pocket Tactics' September 26, 2026 update — “We added three new Shigaku codes to our list for extra rerolls. We also made sure the other codes on our list still work.” — merged with the overlapping code lists from GameRant and PCGamesN. The three new entries there are lapeace, JUSTTHESTART, and bugfixes.

Every reward in the table is rerolls — no code is reported to grant anything else. The strings and amounts are as reported by those guides, not confirmed in-game. Codes are time-sensitive: in GameRant's snapshot, “No Shigaku codes have expired yet, but don't waste time redeeming the active ones above, as they could expire at any moment!” Code lists also differ between guides because they're written at different times, so treat this table as the September 26, 2026 picture and confirm current status in the Discord “codes” channel (details below).

How to redeem codes and claim your rerolls

Roadmap

1. 1

   Join the community group

   Clear the step that sits first in most redemption walkthroughs

   • Join the official (私学 ) Shigaku Roblox community group
   • Pocket Tactics and GameRant list this step first, while PCGamesN's steps leave it out — joining first removes the risk either way
2. 2

   Launch Shigaku

   Get in game to the point where redemption works

   • Launch Shigaku on Roblox
   • Wait until you spawn on campus (PCGamesN's steps have you pick your character here)
3. 3

   Open settings

   Reach the menu that holds the codes box

   • Open the menu — the button sits in the top-left corner of the screen
   • Hit “settings”
4. 4

   Find the Codes box

   • Click the “codes” tab
5. 5

   Redeem a code

   • Paste a working code into the Codes box
   • Hit redeem to claim your rewards
6. 6

   Check and spend your rerolls

   Confirm the rerolls landed before spending them

   • Check your rerolls
   • Use them when you want a new face or a different set of abilities

These published steps cover claiming rerolls only. GameRant's spending tip — “Check your rerolls, then use them when you want a new face or a different set of abilities” — covers face and ability changes, and no published walkthrough extends the procedure to the surname reroll itself. You'll need to locate the surname option in the in-game customization menu, and what one surname roll yields isn't documented.

Getting more rerolls: code cadence and the Discord codes channel

New codes top the reroll supply back up. How often they come out is up to the developer, (私学 ) Shigaku — Pocket Tactics calls the developer “quite hard to read”, though codes tend to arrive after the game updates or hits likes or visits milestones. New codes are often lumped together in the official Shigaku Discord server: to join, scroll to the bottom of the game page and click the link in the socials section, then look for the “codes” channel along the left of the screen — it holds the list of every working code you can still claim. Stock up there and you'll have rerolls ready for your next change, surname included.
