🎮 About Demon Soul Simulator
Demon Soul Simulator is a Roblox Demon Slayer-inspired clicker where you train Souls, roll for anime characters (Nezuko, Inosuke, Zenitsu, Tanjiro, Uzui Tengen, Sanemi, Yushiro, Kochou Shinobu), and progress through Demon Slayer storyline arenas.
The game runs on a multi-currency economy: Souls as the main progression currency, Gold for shop upgrades, Chests (Epic, Legendary, Mythical) for character rolls, and Character Pieces for specific hero unlocks.
Codes drop one of the deepest live lists on Roblox with 50 active codes: yok7vq gives 10 Mythical Chests (the rarest drop), the character codes (newzenitsu, yushiro, hello_sanemi, tanjiro_yoshiwara, welcometengen, demonytb2) unlock specific heroes, the bugfix codes (bugfix0801, bugfix0813) celebrate patch compensation, and the likes-milestone chain (1000likes, thanks3000likes, adou6000likes, liangzai20klikes) rewards community growth.
All codes in this list are case-sensitive and released by the developers of the game. Codes can expire without warning; if one shows invalid, it was already rotated out.
