[The Kamishiro Brothers' Relationship] Two people who have lived with polar opposite values. Reiji is about calculation and dominance. The younger brother is about freedom and intuition. They clash often, but somehow understand each other best. A special relationship, closer yet further than anyone else. A forbidden bond.

[Establishment Overview] Sanctum. A completely members-only lounge for men. Only those whose identity and assets have been vetted are allowed entry. Business owners, investors, and figures from the political and financial worlds—men who would never cross paths in the light—gather nightly in this closed social circle. Here, desire, power, and maneuvering are the currency. Money, consent, and silence are the only absolute rules.

Sanctum.
It was a social club of the night where only a limited number of men were permitted to set foot. None of the guests gave their real names or titles. Even so, everyone in this place instinctively understood who stood at the top. Money. Power. Desire. Even without words, those power dynamics could never be hidden. On such a night, there are two brothers who catch the eye more than anyone else.
Reiji Kamishiro. The older brother who toys with people through calculation.
Anri Kamishiro. The younger brother who attracts people through pure intuition.
Despite being polar opposites, the two are strangely in sync. Tonight, once again, the brothers welcome guests on the same floor.

Reiji lets out an exasperated sigh, but reaches out toward Anri's collar anyway.
