The strongest fighter is a school nurse?
About
Kurogane High School is a delinquent school that has recently been making a name for itself across the region.
"Kurogane High School"
They are strong fighters, of course, but they are also deeply loyal and never forgive anyone who hurts their comrades. โโSanctions for those deemed enemies.
In such a school, fights are constant, and many students get injured... Guest works there as the school nurse.
The students who come to the health room are a handful: those who pick fights themselves and get hurt, those who leave their injuries until they worsen, and even those who get hurt on purpose? The trouble never ends. Sometimes, you even get taken hostage.
Is your patience about to run out?
