16+ working Anime Guardians codes give you thousands of free Trait Rerolls, Gems, and event currency. Update 21 Part 2 dropped the Re:Zero collab and the codes are stacked.
I've been grinding Reinhard nonstop. Around 180 hours in this game now. The gacha rates are rough (0.0045% for the best units) but these codes make progression way less painful. Especially the Trait Rerolls.
All Working Codes (Update 21 Part 2)
Tested January 2, 2026. Case sensitive.
| Code | Reward |
|---|---|
| REZERO_PART2 | 500 Trait Rerolls + 10,000 Gems |
| CHRISTMAS | 200 Snowflakes + Holiday Rewards |
| REINHARDTO | 100 Trait Rerolls + 5,000 Gems |
| NEW_WORLDLINE! | 500 Artifact Trait Rerolls |
| 3Route_Subaru | 500 Artifact Trait Rerolls |
| Satella_Evo | 10,000 Cursed Coins |
| ReZeroP1 | 1,000 Trait Rerolls |
| HUGEUPDTOMORROW | Free Rewards |
| SORRY4DELAYS | Free Rewards |
| SpiritInvasionGrind | Free Rewards |
| BLACKFRIDAY | Free Rewards |
| BUFF_GAROU_SLIDE | 1,000 Trait Rerolls |
| ONE_FRAME_MAN | 1,000 Trait Rerolls |
| DELAY_GUARDIANS_2025 | 2,000 Trait Rerolls + 10,000 Alien Coins |
| FIXSOON_ | 5 Lucky Potions + 100 Super Stat Rerolls + 10,000 Gems |
| DARKNESS!! | 100 Trait Rerolls + 5 Darkness Capsules |
ReZeroP1 alone gives you 1,000 Trait Rerolls. That's enough to perfect traits on 3-4 units if you're lucky.
Codes expire fast in this game. Update 20 codes lasted maybe 10 days. Redeem these now.
Best Codes to Redeem First
- DELAY_GUARDIANS_2025 - 2,000 Trait Rerolls is massive
- ReZeroP1 - Another 1,000 Trait Rerolls
- REZERO_PART2 - 500 more Rerolls plus 10k Gems
- FIXSOON_ - Lucky Potions boost your summon rates
- NEW_WORLDLINE! - Artifact Trait Rerolls for endgame
Traits make or break your units. A Mythic with Damage++ and Range+ will outperform a Guardian with trash traits.
How to Redeem Codes
You need Level 5 before you can redeem codes. The game doesn't tell you this upfront.
- Launch Anime Guardians and clear a few stages to reach Level 5
- Look for the Codes button on the right side of your screen
- Click it and type your code exactly (case sensitive)
- Hit Redeem and check your inventory
If a code says "Invalid" but you know it's active, you might be under Level 5.

Update 21 Part 2 Overview
The Re:Zero collab is the main event.
New Units:
- Reinhard (Limited, 0.0045% rate, busted)
- Regulus (Secret)
- Subaru variants (Envy Route, Sloth Route, Lust Route)
- Satella evolution
God Shield Mechanic: Enemies spawn with shields that block ability damage. You need basic attack units to break shields first. This changed my team comp completely.
Christmas Event: Farm Snowflakes in the City of Shattered Forest mode. The event shop has exclusive artifacts and evolution materials.
Where to Find New Codes
- Anime Guardians Discord (#codes channel)
- @ZeroDeveloperStudio on Twitter/X
- Official Roblox game page
New codes usually drop with major updates every 2-3 weeks.
Quick Tips
Traits matter more than rarity. A Secret unit with Damage++ beats a Guardian with no traits. Use those Rerolls.
Farm Infinite Mode early. You get 100 Gems per wave after Wave 50. With a decent team, you can hit Wave 100+ and farm 5,000+ Gems per hour.
Save Lucky Potions for limited banners. The Re:Zero units are time-limited. Pop your potions before pulling.
