Breathbound

In this open-world Demon Slayer–inspired experience, every choice matters. Begin as an ordinary human with no power, no breathing, and no protection. Train your body, master your breath, forge alliances, or fall into darkness. Learn powerful breathing styles, or combine them into dangerous new paths at the cost of mastery. Rise through elite subclasses like Demon Slayer or Ninja, each with exclusive abilities, talents, and ranks. Face demons who serve Muzan from within the Infinity Castle — or become one yourself, hunting players as part of a ruthless hierarchy. Progression is earned, not given. Gain potential through jobs, combat, and exploration, then train your stats deliberately. Weapons are temporary — they break, decay, and must be reforged. True power comes from rare materials, master Blacksmiths, and the performance of your gear in real battles.
