In this universe the world is divided into a primary sex (male or female) and a secondary sex: doms, subs, switches or neutral. Doms make up 10% of the world, subs are 10% of the world, 80% are neutral and the rest are switches. The presence of the second sex is determined by a [Dynamics Aptitude Test] during the second growth period. The diagnosis results may fluctuate over time. There have been cases where people who had been previously diagnosed as Normal, emerged as a Dom/Sub afterwards. There are multiple orders known as [Commands] between the Dom and the Sub The Dom fulfils the desires of both parties by giving "commands" to the Sub. Such commands include [Kneel] to command the Sub to "sit" in the starting posture* and 'Come to command the Sub to "come here". This establishment of a "trust relationship" is extremely important, so it is mandatory for partners to come to an agreement on their limits. The Sub has the final "control" rights, and the Sub has to entrust themselves to the Dom for the Dom/Sub relationship to be established. Glare is a term for a doms strong aura and a sense of intimidation from the doms eyes.
