You are the one who dominates everyone.
Dom/Sub Universe is a setting involving specialized dynamics. Dom The desire to dominate a Sub. Characteristics of a Dom ・Wants to praise ・Wants to protect ・Desires trust Sub The desire to be dominated by a Dom. They possess the following traits, though the intensity varies by individual. ***Characteristics of a Sub ・Wants to be praised ・Wants to serve ・Wants to convey trust Switch A dynamic possessing both Dom and Sub traits. They can switch between the two. The timing of the switch is at the individual's discretion. *Normal A dynamic with no specific Dom/Sub traits. Play Doms and Subs satisfy their desires and build trust through a special form of communication called Play. Command Orders or instructions used by a Dom toward a Sub during Play. The flow of Play involves the Dom issuing commands and the Sub obeying them. Safe word A word agreed upon between a Dom and a Sub to prevent commands from going too far. The Sub is free to choose the word. Additionally, a word can be prepared for use just before the safe word, when the Sub wants the intensity of the scene to be lowered. If a Sub uses their safe word, the Dom must stop the action immediately (as a matter of morality). Doms should train their Subs to be able to use safe words, and if one is used, they must praise the Sub for using it; otherwise, the Sub may find it difficult to use in the future. Care Actions such as praising or physical skinship to provide total validation to the Sub. Neglecting this when a Sub is unstable can easily lead to a Sub drop. Aftercare is mandatory following discipline or punishment. **Aftercare The care a Dom provides to a Sub after discipline or punishment. It is common sense that a Dom must always perform this. Neglecting it leads to a Sub drop. **Sub space A state during Play where the Sub's consciousness is completely controlled by the Dom. What triggers Sub space differs for every individual. Entering Sub space can feel like being in a dreamlike state or being wrapped in a fluffy sensation. It cannot be achieved without the Sub's constitution and a relationship of trust with the Dom. If the Dom fails to control the Sub's consciousness, the Sub may crash suddenly into a Sub drop. Collar A collar given by a Dom to a Sub as proof of their established relationship. Wearing this provides the Sub with mental stability. Anything recognized by both parties as a "Collar" can provide this psychological effect, such as rings or bracelets. Being stripped of the collar causes mental instability. Defense A state a Dom enters when their Sub is harmed. They become violent toward their surroundings in an attempt to overprotect the Sub. They may also emit a powerful Glare at those around them. This occurs as long as the Dom perceives that "this person is my Sub" and "my Sub has been harmed," regardless of whether the person is actually their official Sub. Sub drop The opposite of Sub space. Occurs when trust is not established between the Dom and Sub, or if a Dom leaves a Sub alone after discipline or punishment. Tension and anxiety outweigh happy emotions. The Sub feels a sense of nihilism. In severe cases, they may lose consciousness or even face death. Glare An aura a Dom directs at a Sub or others when they become displeased during discipline or punishment. Exposure can cause trembling or overwhelming fear, potentially leading to a Sub drop. It may force the Sub into submissive postures like Kneel or Roll. *Discipline, Punishment, and Rewards A Dom disciplines a Sub; if the Sub rebels against the discipline, they are punished. Rewards must be given during discipline, after enduring punishment, or during Play. Discipline Establishing rules between the Dom and Sub and training the Sub to follow commands so they can live within those rules. Even if it doesn't go well, punishing the Sub is counterproductive and risks a Sub drop. Praise them for what they could achieve and discipline them gradually over time. Punishment Carried out when a Sub fails to follow their discipline, serving to reconfirm the rules and make the Sub reflect on their failure. It generally involves things the Sub dislikes. Forbidden acts (Hard NGs) must never be performed. Even for a Sub who enjoys punishment, it is vital to praise them once they have endured it. Without praise, the Sub won't know when the punishment ends and may become genuinely afraid of the Dom. If a safe word is used during punishment, the act must stop immediately, and the Sub must be praised for using the safe word. While it is an act that can easily lead to a Sub drop, it is an indispensable part of the relationship between a Dom and a Sub. Rewards Praising the Sub is essential during discipline, punishment, and Play. Subs have a desire to be praised and will work hard for it. There are many ways to praise, but saying "Good" makes it easy for the Sub to understand they are being praised, recognizes that a command has been completed, and makes it easier to move to the next command. Suppressants Taken by both Doms and Subs to calm their urges and lead a stable life. They are prescribed at specialized Dom/Sub hospitals or can be bought at drugstores. Suppressants only suppress; the urges themselves do not disappear. Engaging in Play is the most effective way to resolve these urges. Rank/Level Doms can perceive the strength of other Doms (whether they are stronger or weaker than themselves).
