Shigaku Codes (September 2026) – Free Rerolls & Rewards

Rerolls are the only thing Shigaku codes produce, which makes this the simplest code list in the school-life genre: there is no premium currency to weigh up and no bundle to compare, only how many attempts at a better roll a string is worth. The table below separates strings that four independent listings agree on from the one string listings still argue about.

Verified by RoboLibrary Editorial on September 27, 2026: The verified set was cross-checked across four independent Shigaku code listings refreshed between September 25 and September 26, 2026, plus a recorded launch-week walkthrough in which the codes menu is opened and strings are entered on screen. Every reward value in the verified table matched across at least three of those listings. The disputed string is isolated rather than dropped, and three single-source strings are recorded as unverified claims. Reward amounts reflect the launch build and change when the developer rebalances.

Shigaku Codes List

Seven strings currently agree across the independent listings checked on September 27, 2026. Six of them share the same shape: milestone and compensation codes from launch week, with rewards scaled to how loudly the community asked for them.

The seven verified strings add up to 123 rerolls. Codes are case-sensitive as written, and the strings on this list are reproduceable exactly as they appear above.

Two of the seven are worth redeeming before your first character decision rather than after. lapeace and JUSTTHESTART are the low-value pair at 10 rerolls each, but they arrive before the milestone codes in the redemption order most players use, so redeeming them first means every subsequent roll decision is made with a fuller reroll pool rather than a depleted one.

Conflicting and Unverified Code Claims

Not every string that circulates during a launch week survives contact with a second source. Three separate credibility tiers came out of the September 2026 checking pass, and the difference between them matters more than the raw string count.

One disputed string. SORRY4DELAYTHATSONUS is the outlier. Two listings carried it as active on September 26, two marked it expired, and recorded launch-week footage shows the string being entered and accepted, reporting 25 rerolls. Because the string is real but its current status cannot be settled from the listings alone, it is tracked here rather than counted in the verified table. Enter it after the seven verified strings; if it is rejected, the most likely reason is that it has now expired rather than that it was never valid.

Three unverified claims. 30KLIKES, 35KLIKES, and 40KFAVS appear on a single listing with no independent corroboration, no published reward detail beyond a reroll figure, and no recorded redemption anywhere. The naming pattern is plausible for a game that awards milestone codes, which is exactly why they are worth trying in the code box once, but they are not counted as working codes and they should not shape a reroll budget. If any of them works for you, the reward is a bonus rather than a plan.

A practical rule for the launch window of any school-life game: a string that appears in three or more listings with an identical reroll figure is safe to trust, a string that appears in exactly two is worth a single attempt, and a string that appears in one is a lottery ticket. The counts on this page follow that rule.

How to Redeem Shigaku Codes

Redemption takes about twenty seconds once you are in a server, but there is a prerequisite that catches people out.

1. Join the official Shigaku community group on Roblox. Several walkthroughs list group membership as a required step rather than an optional one, and joining is free.
2. Launch Shigaku and pick your character at the title screen.
3. Open the menu from the left side of the screen. Pressing M on PC does the same thing.
4. Open Settings, then select the Codes tab.
5. Enter the string in the code box and press Redeem.

If a string is accepted, the rerolls land immediately and show up on the Appearance and Profile screens. If nothing happens at all, that is a different symptom from a rejection — the September 26 patch added messaging for rerolls that animate without changing anything, so a silent no-op now means the roll was blocked rather than that the string failed.

Where to Spend the First Rerolls

Rerolls are shared across three unrelated screens, so the order you spend them in decides whether 123 attempts buys a competitive character or a well-dressed one. The rarity bands published by the developer are the only honest guide here.

Fighting styles roll from a banded table: Common at 78 percent, Uncommon at 21 percent, Epic at 1 percent, and Shiny at 0.001 percent. That distribution means the single most common mistake is treating the style roll like a slot machine worth draining. Roughly four out of five rolls land on Basic, so a player who rerolls hunting for Shiny will spend everything and very likely finish with a worse style than the Boxing or Karate they rolled past.

The band that is genuinely worth stopping on is Uncommon. Boxing and Karate together cover 21 percent of rolls, both are competitively viable, and each arrives with two named perks rather than a cosmetic tag — Boxing patches parry and combo reliability, Karate adds forward pressure and faster string recovery. Stopping on either one and moving your remaining rerolls to appearance is the efficient play.

Identity and Appearance rolls are where the rest of the budget should go, and two of them are worth prioritising over cosmetic polish. Ethnicity is the only roll that changes other stats: Japanese is a 95 percent outcome and the other 46 ethnicities sit near 0.109 percent each, and your ethnicity shifts average height along with hair and skin tone options. Fighting reach and posture are both affected by build, so a character roll made early is cheaper to get right than one corrected later. Faces, hair, and mouths can wait, especially now that rare hair and rare styles prompt for confirmation before being rolled over.

Spend order that holds up in practice: verify the strings, roll fighting abilities until Boxing or Karate lands, roll ethnicity and height once, then spend whatever is left on faces and hair.

Why a Shigaku Code Is Refused

There are three distinct failure modes and they have different fixes.

The string is expired. Launch-week compensation codes are the first to go, and the disputed string on this page is the likely candidate for removal. Expiry is normally documented by a listing update rather than announced.

The server is stale. Shigaku's live build was updated on September 26, 2026, and the same patch changed the reroll system's retry and confirmation behaviour. A server that has not picked up the new build can refuse a string that works elsewhere, which is why rejoining is the first fix rather than the last.

You have already redeemed it. Rerolls are credited once per account per string. A string that worked yesterday and fails today is usually a duplicate rather than an expiry.

Change Log

• 2026-09-27: Verified seven active Shigaku codes worth 123 rerolls across four listings and a recorded redemption; isolated SORRY4DELAYTHATSONUS as a disputed string; recorded 30KLIKES, 35KLIKES, and 40KFAVS as unverified claims.

FAQ

How many Shigaku codes are working right now?

Seven strings were verified on September 27, 2026, worth 123 rerolls in total. A further string is disputed between listings and three more are single-source claims, all tracked separately on this page so the verified count stays honest.

Do Shigaku codes expire?

They do. The launch-week set is compensation-flavoured, and codes tied to milestones or bugs tend to be removed once the milestone passes or the bug is fixed. SORRY4DELAYTHATSONUS is the clearest example: it was demonstrably valid during launch week and is now marked expired by half the listings tracking it.

Can I redeem the same Shigaku code on a second character slot?

No. Redemption is per account, so a string is spent once no matter how many character slots you own. With the Unlock All 3 Slots game pass, that matters more than it first appears: your reroll pool is shared across all three characters, so a slot you roll badly on costs future slots attempts.

Do Shigaku codes ever give fighting styles directly?

No. Codes pay rerolls only; there is no string that grants a specific style. Getting Boxing, Karate, or anything rarer always runs through the same banded roll table, and the full perk breakdown for each style sits on the Shigaku combat page.

What else should I do with my first session besides redeeming codes?

Claim the codes, then plan the session around class points rather than cosmetics. Class D is the starting rank for every student, and wins in sports, rated chess, and tournament fights all feed the global ladder. The Shigaku beginner guide orders that first session, and the Shigaku wiki explains the workout and activity systems that feed it.
