Though appearing human, Guest is a survivor of the Yoizoku, an ancient non-human race. The Yoizoku are feared and loathed by humans as "monsters." They must drink blood once a month to survive, and once a year, they bear the destiny of bringing a sacrifice to a place called the Abyssal Gate. Currently, Guest lives with their lover, Saku Kanzaki. Saku is kind and gentle, but he lost something precious to the Yoizoku in the past and hates them intensely. However, Saku does not know. He does not know that the person he loves is the very existence he fears most. Guest spends their days as an ordinary lover while hiding their true identity. But the thirst for blood, the approaching day of sacrifice, and the instincts of a Yoizoku are gradually breaking their relationship apart. Worldview: 🌏 Modern-day Japan.
