Project Mugetsu Codes (May 2026) — All Active & Expired Codes
Here are all the working Project Mugetsu codes for May 2026. Redeem them for free RRA potions, Legendary Orbs, Mastery and EXP Boost Potions, Race Resets, Gold, and Clan Spins. We've listed every active and expired code below, along with a full redemption walkthrough.
Project Mugetsu is a Bleach-inspired RPG on Roblox where players choose between becoming a Soul Reaper or a Hollow, unlock powerful abilities through progression trees, and battle across iconic locations from the anime. With over 1.5 billion visits and a dedicated player base, the game receives frequent updates that introduce new factions, abilities, and clan mechanics. The Factions update in early 2026 brought one of the biggest content drops the game has seen, adding faction-based PvP territory control and several new progression paths.
Codes in Project Mugetsu give you a serious head start. Reroll Ability potions (RRA) let you re-roll your Shikai or Resurreccion abilities, which normally costs Robux. Legendary Orbs are used for high-tier summons, and Race Reset Potions let you switch between Soul Reaper and Hollow paths without losing progress on your save file. Free Gold and Clan Spins round out the rewards, making each code worth redeeming immediately.
All Active Project Mugetsu Codes (May 2026)
These codes are confirmed working as of May 18, 2026. Copy them exactly as shown and redeem them before the developers deactivate them.
| Code | Reward | Status |
|---|---|---|
| Factions! | 25 RRA, 25 Legendary Orbs, 10 Mastery Potions, 10 Exp Boost Potions, 5 Race Reset Potions, 100,000 Gold, 300 Clan Spins | Active |
| Factions26 | 20 RRA, 10 Legendary Orbs, 50 Mastery Potions, 50 Exp Boost Potions, 15 Race Reset Potions, 300,000 Gold, 50 Clan Spins | Active |
| ValentinesDay26 | 25 RRA, 20 Legendary Orbs, 25 Mastery Potions, 10 Exp Boost Potions, 5 Race Reset Potions, 75,000 Gold, 200 Clan Spins | Active |
| WeAreBackAgain | 100 RRA, 100 Legendary Orbs, 50 Mastery Potions, 25 Exp Boost Potions, 10 Race Reset Potions, 200,000 Gold, 250 Clan Spins | Active |
| ExtraSpins400 | 400 Spins | Active |
| HappyEaster26 | 40 Reroll Ability Potions, 1 Race Reset Potion, 400 Clan Spins, 10 Legendary Orbs | Active |
Between these six active codes, you can claim a combined 210 RRA potions, 165 Legendary Orbs, 135 Mastery Potions, 95 Exp Boost Potions, 31 Race Reset Potions, 675,000 Gold, and over 1,200 Clan Spins. That's an enormous amount of free resources if you're starting a new save or re-rolling for a better ability on an existing one.
The WeAreBackAgain code alone gives 100 RRA potions, which would cost hundreds of Robux through the in-game shop. If you've been waiting for a good time to re-roll your Shikai or Resurreccion, redeem that code first and start spinning.

How to Redeem Codes in Project Mugetsu
Redeeming codes in Project Mugetsu works a bit differently from most Roblox games. You don't enter them through a separate menu or settings button. Instead, the code field appears on the character selection screen. Here's the step-by-step process.
- Open Roblox and launch Project Mugetsu from the game page.
- On the main menu, select your save profile or character slot. You must choose a save before the code field becomes visible.
- Look at the bottom left of the screen for the Redeem Code text field. It appears below the character preview.
- Type or paste your code into the text field exactly as shown, including any capital letters or special characters.
- Click the Redeem button next to the text field. A confirmation message will appear on screen if the code was accepted.
Where Do New Project Mugetsu Codes Come From?
The Project Mugetsu development team, led by OsirisProductions, releases codes through several channels. Their official Discord server is the primary source. Most codes get announced in the announcements channel before they appear anywhere else online. Following that server is the fastest way to claim codes before they expire.
Major game updates are the most reliable trigger for new codes. The Factions update, which added faction-based territory wars and new progression mechanics, came with two dedicated codes (Factions! and Factions26). Seasonal events like Valentine's Day and Easter also tend to bring their own reward codes. The developers have been consistent about releasing codes alongside holiday events since late 2025.
Community milestones have historically generated codes as well. When Project Mugetsu hit 1 billion visits on Roblox, the developers dropped the ThanksFor1B code with generous rewards. As of May 2026, the game sits well above that milestone, and future visit count celebrations will likely bring more codes.
The developers also occasionally release "apology" or "compensation" codes after extended maintenance periods or bug fixes. The WeAreBackAgain code, which offers 100 RRA potions, is one of the most generous codes the game has ever seen and appeared after a period of downtime and major patches.
Tips for Getting the Most Out of Project Mugetsu
Redeeming codes is just the starting point. How you spend those free resources matters more than collecting them. Here are some strategies that experienced players use to maximize their progression.
Save your RRA potions for high-level abilities. Re-rolling your Shikai or Resurreccion at lower progression tiers wastes potions because the ability pool expands as you rank up. If you're still working through early Soul Reaper or Hollow progression, hold onto your RRA potions until you've reached Bankai or Segunda Etapa. The legendary-tier abilities at those stages are what you actually want to roll for, and each attempt uses the same number of potions regardless of your level.
Stack Exp Boost Potions during double XP events. Project Mugetsu occasionally runs weekend double XP events, and the Exp Boost Potions from codes stack on top of that multiplier. Grinding Hueco Mundo or Soul Society missions during a stacked boost period can cut your leveling time by more than half. With 95 free Exp Boost Potions from the current codes, you have plenty to save for the next event window.
Use Clan Spins strategically. Clans in Project Mugetsu provide passive stat bonuses and unique perks. Some clans like Kuchiki and Zaraki are significantly stronger than others for specific builds. With over 1,200 free Clan Spins available from current codes, you have enough attempts to aim for a top-tier clan. Don't settle for a mid-tier result when you have spins to spare.
Race Reset Potions are arguably the most valuable free item in the game. Switching from Soul Reaper to Hollow (or vice versa) normally costs 500 Robux, so 31 free race resets represent serious value. Test both paths before committing your build. For a deeper breakdown of progression strategies and how to earn Robux for premium items, check out our Project Mugetsu free Robux guide.

Frequently Asked Questions
Open Project Mugetsu, select your save profile or character from the main menu, then look for the Redeem Code text field on the bottom left of the screen. Enter the code exactly as written and click the Redeem button. Rewards are added to your inventory immediately.
The most common reasons are expired codes, already-redeemed codes, or incorrect formatting. Project Mugetsu codes are case-sensitive and some include special characters like exclamation marks. Make sure you've selected a save profile before trying to redeem, as the code field won't function without one.
There's no fixed schedule, but codes typically appear with major game updates, seasonal events, and community milestones. The Factions update and Easter 2026 event both came with dedicated codes. On average, you can expect new codes every few weeks during active development periods.
No. Each code can only be redeemed once per account. If you attempt to use a code a second time, the game will display an error message indicating it has already been claimed.
Yes, most codes have a limited lifespan. Developers can deactivate them at any time, and event-specific codes like HappyEaster26 are particularly likely to expire once the event ends. Redeem every code as soon as you see it to avoid missing out.
The official Project Mugetsu Discord server is the fastest source for new codes. Developers also announce them through in-game notifications and social media. Bookmark this page for a regularly updated list — we add new codes within hours of their release.
