ABOUT THE SERIES

Based on a bestselling BL light novel with over 1.4 million copies sold, the anime follows Seiichirou Kondou, a stressed-out office worker who gets pulled into another world through a saint-summoning ritual. True to form, he asks for a job and ends up working for the Royal Accounting Department.

After discovering a tonic that erases fatigue, his health problems vanish—but it also turns out the magic-rich elixir is deadly to humans without proper resistance. His only shot at survival lies in the hands of Aresh, the stoic and powerful captain of the Third Royal Order.

This unusual workplace romance between a no-nonsense accountant and a cold but dependable knight is about to unfold on screen for the first time.
