Update: checked for new Slayer Training codes on January 8, 2026
Slayer Training is inspired by the Demon Slayer animanga series, where you need to train your body to the maximum in order to compete with other players. As you complete the reps with dumbbells and complete your sets, you gain power. With each session, you must push your limits to become the strongest Hashira. Also, there are a few cute pets who will stay by your side and boost your training. If you’re looking for more boosts in the game, grab on to these active Slayer Training codes that will give you strength potions, damage potions, and some gems as well.
