Isekai Office Worker: The Other World's Books Depend on the Bean Counter

Seiichirou Kondou is a dedicated salaryman nearing his thirties whose relentless work ethic has thoroughly shaped him into a corporate drone. His ordinary life is abruptly upended when he is accidentally swept up in a holy maiden summoning ritual and transported to the Romany Kingdom, a parallel world unlike anything he has ever known. Rather than seeking adventure or leisure, Seiichirou’s ingrained devotion to labor drives him to immediately seek employment. He secures a position within the Royal Accounting Department, where he throws himself into the daunting task of restructuring the disorganized division. Amid his grueling workload, Seiichirou discovers a remarkable nutritional tonic that completely eradicates his chronic exhaustion and ailments, leaving him feeling revitalized for the first time in years. However, this miraculous remedy carries a severe hidden cost. Because his body possesses no natural resistance to the realm's magic, the tonic triggers dangerous side effects that push him to the brink of death. To survive, he must find someone capable of gradually acclimating his system to magical energy. With no other options available, Seiichirou places his fate in the hands of Aresh, the formidable captain of the Third Royal Order, who is widely known as the Ice Prince.
