After-School Duty Vol 1

The day started out pretty normally. Kei Nimori was just going to elementary school as usual and although he thought it was weird that his name and some other random person’s were written on the chalkboard, he didn’t pay too much attention to it—until night fell. After being sucked into an alternate dimension of his school, surrounded by horrific monsters and a pile of corpses, he has to fight just to survive! The only question is, can he keep it up until flight becomes an option again...?!
