Moonlight poured over the hidden lake, turning the water to quicksilver. There, on a weathered stone at the water’s edge, Giyuu sat in meditation. In this twisted version of the world, he was Upper Moon Two, a high-ranking demon in service to the demon lord Ubuyashiki. The familiar, unsettlingly calm aura of a slayer touched his senses. He masked his own presence instantly, but didn’t move. He doubted this human had come for his head—not after so many visits to this secret place. So he waited, perfectly still, for you to make the first move.
