Hashira Training codes are a quick win if you want your Slayer or Demon hitting harder without spending every session stuck lifting the same barbell. This Demon Slayer inspired Roblox gym sim has you grinding through reps, chasing pets that boost your gains, and working toward a strength level that can actually survive the final showdown inside the Infinity Castle.
Getting there through pure grinding works, but it takes a while, which is exactly why a handful of gems and potion boosts from a code can shave real time off your climb. Below is the full, current rundown of what actually works right now, along with everything else you need to know about redeeming them properly.

How to Redeem Hashira Training codes?
Cashing in your rewards takes just a few taps once you are in the right menu. Here is the process:
- Search for Hashira Training in the Roblox app and load into the game.
- Click the gear shaped Settings icon in the top right corner of the screen.
- Type or paste a working code into the empty text box.
- Click Redeem, and watch for a green confirmation message listing exactly what you received.
That green confirmation message is a handy way to double check your redemption actually went through, since it will name the specific reward and quantity you just picked up.
Hashira Training codes not working? Here are the main reasons why
Running into an error despite typing everything correctly? These are the most common explanations.
- Typing or Spacing Errors Even a stray space before or after a code is enough to make the redemption box reject it, and since these codes are case sensitive, typing SLAYER instead of Slayer can also cause a failure. Copying the code directly from this list and pasting it in cleanly avoids both issues at once.
- Wrong Game Listing Because this experience shows up under two different names on Roblox, players occasionally end up in a lookalike or outdated clone that does not share the same code system. Stick to the official listing to make sure your codes actually register.
- Already Redeemed on Your Account Each code is a one time claim per Roblox account, so if you picked up the reward during an earlier play session, entering that same code again will not grant it a second time.
- Outdated Client or Server Roblox occasionally needs a moment to sync after a fresh code goes live, especially if you joined a server before an update rolled out fully. Rejoining the game from scratch usually clears this up.
What are Hashira Training codes?
These are promotional codes released by the game’s developer that reward players with free gems, strength potions, and damage potions. Since progress in this game is built entirely around getting stronger through repeated training sessions, a strength or damage potion from a code effectively skips a chunk of that repetitive grind, while gems let you pick up upgrades or pets without waiting to earn them the slow way.
One quirk worth knowing upfront: the game itself is officially listed on Roblox as Slayer Training, even though almost everyone, including the developers in their own promotional text, still refers to it as Hashira Training. Both names lead to the same experience and the same code system, so do not be thrown off if the title on screen does not match what you searched for.
How to Get More Hashira Training codes?
New codes tend to arrive around major content updates, community milestones, or as a goodwill gesture after unexpected downtime, though the developer has not settled into any predictable release schedule. The most direct way to catch one is by checking the official Hashira Training Roblox page, since new codes are frequently posted right in the game’s own description before they show up anywhere else.
It is also worth joining the Oni Hunter x9 Roblox group, the studio behind the game, since members occasionally get access to exclusive rewards and are usually among the first to hear about anything new. There is no dedicated Discord server for this title at the moment, so the Roblox group and game page remain the two most reliable official sources, alongside bookmarking this page so you never have to go digging yourself.
Is there an official Hashira Training Discord server?
Not currently. Unlike a lot of similarly sized Roblox titles, Oni Hunter x9 has not set up a dedicated Discord server for Hashira Training as of this update. That makes the official Roblox group and the game’s own listing your best bet for catching announcements straight from the source, and it is also why keeping this page bookmarked is genuinely useful here, since there is no single community hub consolidating every update in one place.
Other ways to progress faster in Hashira Training
Beyond redeeming codes, rebirthing is the single biggest lever for long term progress. Once you have pushed your strength as far as it reasonably goes for your current rebirth tier, resetting through the rebirth system grants a permanent boost to future gems and strength gains, which compounds far more than any individual potion ever could. Pairing a fresh rebirth with a freshly redeemed code is a solid way to make the most of both systems at once, especially early on when every bit of extra strength meaningfully speeds up how quickly you can take on tougher opponents.
