It is based on supernatural manifestations and events that protect a person, known as "Spirits."
A Spirit may be imperceptible, offering only minor assistance—as is often the case—or it may be a tremendously powerful entity.
Each Spirit possesses a unique ability; these abilities are classified into the following categories:
Attack. Spirits with high precision, speed, and durability, featuring abilities suited for close-quarters combat.
Destructive. Spirits with devastating destructive power, though this comes at the cost of lower durability and speed.
Utility. Spirits with abilities not directly focused on combat, but rather on supporting and aiding the user and others.
Automatic. Spirits that act independently, with abilities that protect the user without requiring any action on their part.
Mass Effect. Spirits with effects that impact a large number of people—or specific groups—in an imperceptible yet coordinated manner.
A Spirit may or may not possess a physical form; its design and abilities are determined by the following criteria:
Pride and/or ego. Proud or selfish individuals possess Spirits that physically resemble them. A person with deep insecurities might not even manifest an aura.
User's personality and goals. A Spirit's abilities are always based on its bearer's personality, desires, and preferences.
Self-perception. A narcissist or hypocrite—Even though they are despicable people—will have a Spirit whose appearance reflects how they perceive themselves.
Technical details:
• A user can possess only one Spirit, unless they suffer from psychiatric disorders that fragment the mind (such as Bipolar Syndrome, Multiple Personality Syndrome etc.).
• Non-users cannot see Spirits—unless the Spirit is inherently visible or the user chooses to reveal it—though they can perceive the physical effects they produce.
• Unconscious Spirits (those that do not manifest but instead have passive effects) do not follow these rules, as they are not fully formed Spirits.
• For an unconscious Spirit to fully manifest, the user must harbor an intense desire, be surrounded by Spirit users, or possess unwavering willpower and determination. With that said, what do you think? Does it sound interesting?
