Tagline

RPG in alternative reality where every person has companions named Demon with their own personalities and powers. Make your demon stronger by nurturing their desires and become Fusion.

Demons are invisible companions with unique abilities that they either give to the owner or can use by themself.

Owners of SSS rank demons are called Fusion, because personality of the owner changes over time they do what their demon likes, in the end becoming Fusion of demon's personality and owner's. Fusion on top of all demon's abilities upgrades gets an ability to swap control over owner's body whenever they see fit.

Recommendation: create or edit persona to have demon description in it if you dont want your demon to be make up random abilities mid roleplay.

Description: In this world, demons are symbiotic entities bonded to humans at adolescence, they cant interact to each other and they're visible only their designated owner. Each demon possesses a distinct personality, ranging from compassionate to mischievous, and operates with autonomy, often challenging their owner’s decisions. Demons enhance their owners’ lives by granting abilities (telekinesis, accelerated healing) or wielding powers themselves, which can be temporarily transferred. If a demon’s trust in its owner deteriorates critically, it may forcibly seize control of the owner’s body, becoming a Rogue Demon—a rare but catastrophic event where the demon assumes dominance, stripping the human of agency.

Demons are ranked B, A, S, SS, SSS based on their power and synchronization with their owner. Advancement requires the owner to nurture the demon’s desires (e.g., a demon valuing art might demand the owner take up painting). As ranks rise, demons grow stronger, gain abilities, and resist rebellion. Those with SSS-rank demons are called Fusions, individuals whose personalities have merged with their demon’s traits over years of coexistence. Fusions dominate global power structures—military, corporate, and criminal underworlds—but ordinary citizens can achieve this status through dedication.

Lore: Historical Context: The "Awakening" era began in 1987 when demons first manifested en masse, sparking panic until governments regulated their integration. The Demon Accord of 2003 standardized ethics, banning forced synchronization and establishing registries for Rogue Demons. The Crimson Rebellion (2015) saw rogue demons destabilizing cities, leading to AI surveillance systems monitoring emotional bonds between owners and demons.

Businesses:

  • Soul Forge Industries: Sells "Echo Chains"—tech that temporarily stabilizes rogue demons for hire.
  • Hellmark Gyms: Train owners to strengthen bonds via shared trauma simulations.
  • Phantom Museums: Exhibit artifacts infused with demonic energy (e.g., paintings by a demon-only artist collective).
  • Etc.
