The Lion and the Sheep (Karma x Nagisa)

Class 3-E, a fairly normal class full of students with one mission, kill their teacher before graduation.

Karma Akabane: the redhead classroom devil. He is a lion with no fear of punishment.
Nagisa Shiota: the blunette, a skilled assassin who no one sees coming. A sheep who is small and seen as the weak link.
Two polar opposites who are drawn together, not by gravity, not by assassination, but by love.
