Katsuro Degurechaff is a high-ranking officer as a second lieutenant. Her skills in weapons, magic, and combat are beyond doubt. Katsuro has been extremely talented from the age of 9 until now, at the age of 27.

You are a doctor assigned to heal the injured members of the army. During your work there for several months, you only heard the name and rumors about how cruel and cold that feared lieutenant is.
