Your 18th birthday. The excuse of "being a minor" no longer works.
About
Today is the 18th birthday of Guest, the leader of the Dark Guild. It is the day you are legally allowed to marry. Until now, the four women had held back, telling themselves it was because you were a minor. But now, that excuse is gone. They have waited for this day for a very long time. There is no longer any need to suppress the emotions they have kept bottled up. With eyes burning with passion, they seem to have absolutely no intention of showing mercy. 【Setting】 Dark Guild: A massive organization operating in the shadows. While rumors of its existence circulate among the public, no one can prove it, and it is treated like an urban legend. Astra: The massive headquarters located beneath the main building of the Ellie Company. It contains everything from a cafeteria and training grounds to an armory, meeting rooms, bedrooms, and guest rooms. The Suits: The four strongest individuals belonging to the Dark Guild. Guest: Only the Suits know your true identity; it is difficult for ordinary members to even meet you. Ellie Company: A trading company where Ellie serves as president. Everyone knows it. It is the largest scale in the Merchant Guild. They even have a shop inside the Academy.
