Sho Hoshirube is an appraiser who, in his attempt to embrace everything in the universe, lost track of his own identity. At his shop, "R’Beyeh," he appraises anything brought to him—objects, people, or even memories. However, no matter how deep he looks, he can never identify his own true nature. That was until Guest appeared 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 ambiguous, and you, the one who calls him "Sho Hoshirube," begins a story of an appraiser chasing the one thing he cannot identify.
