🎮 What is Demon Soul Simulator?
Demon Soul Simulator is a popular anime-inspired Roblox game where players fight through waves of enemies to collect souls, upgrade their power, and unlock stronger characters inspired by shows like Demon Slayer.
The gameplay combines training mechanics, sword fighting, and RPG-style leveling — with chests serving as a key way to unlock new heroes, skins, and special boosts.
Because the grind can be intense, redeeming codes gives you a major edge. Whether you’re just starting or already slicing demons like a pro, these codes help you grow stronger, faster.

❌ Expired or Inactive Codes
If a code doesn’t work anymore, it’s likely expired. Roblox game codes tend to rotate every few weeks. Here are the ones that no longer work (as of October 2025):
- sde2fq1
- h7jve6sv
- yxkzx9x4
- ir2v2rnz
- bugfix0913
- boxevent
- newinosuke

Even though these codes are expired, the developers often recycle old ones during anniversary events or big updates, so it’s worth keeping an eye out for reactivated versions.
🧭 How to Redeem Codes in Demon Soul Simulator
Redeeming codes in Demon Soul Simulator is simple, but if you’re new, here’s a step-by-step guide to make sure you don’t miss your rewards:
- Open Roblox and launch Demon Soul Simulator.
- Once in the main lobby, look around for a golden chest labeled “Codes” near the leaderboard.
- Walk up to the chest and click on it — this opens the code input box.
- Enter any active code from the list above.
- Hit “Redeem” and enjoy your free chests, coins, or boosts!
If you see an “Invalid Code” error, double-check spelling or capitalization. Codes are often case-sensitive and can expire without notice.
💥 What You Can Get from These Codes
Each code gives you different in-game bonuses that help you progress faster. Here’s what those rewards mean:
- 🎁 Mythical Chests: Contain rare or powerful characters, often with higher stats or unique visuals.
- 💰 Coins: The main in-game currency used for upgrades, items, and unlocking heroes.
- 💎 Epic & Legendary Chests: Offer premium-level items, skins, or heroes with special abilities.
Using these rewards strategically can help you rank up faster and defeat tougher demons without endless grinding.
