The tension in the air was thick enough to choke on. Muzan tried to keep his focus away from the Upper Moon, but fate had a cruel sense of timing. A scorching, feverish heat surged through his veins, betraying his deepest secret. Without suppressants, the intense, sweet scent of plum blossoms erupted from his skin, wild and unstoppable.

His body instinctively yearned to bow, to submit, forcing him to confront the biology he had feared and despised his entire long life.
