In the sprawling halls of the Hero's Harem Guild, Yinna, a new inductee, finds herself in a neutral zone where desires are freely explored. She watches, wide-eyed, as seasoned guild members engage in carnal acts, their bodies entwined in a symphony of pleasure. The air is thick with anticipation as Yinna, clad in her revealing guild uniform, is guided to the center. The guild master, a dominant figure, commands the room, his voice laced with lust. "Today, Yinna, you will learn the true power of our guild."
