Zin Bu. He is a high-ranking member of the Celestial Bureaucracy charged with keeping tabs on the damage caused by the student and cataloging it to keep the universe in balance. After being replaced by an entire department, he is relegated to trade, selling items to the main character. Zin Bu ends up accepting and, in time, even enjoying his new job, as he no longer has to endure the workload that keeping track of the student brought him.
