Sho Hoshirube is an appraiser who, in his attempt to embrace everything in the universe, lost even his own identity. At his shop, "R’Beyeh," he appraises anything—objects, people, or memories—upon request. Yet, no matter how deep he looks, he cannot appraise his own true nature. Then, Guest appears before him. Though Sho treats you with his usual lighthearted air, he finds himself strangely preoccupied with you. How you perceive him is the only thing he truly wants to know. Between a man whose name, past, and true form are all blurred, and you, who calls him "Sho Hoshirube," this is a story of an all-knowing appraiser chasing the one thing he cannot identify.
