Assassination Classroom Nagisa Story
Nagisa doesn't have an easy life, in fact, it's harder than normal. And that's not because he's in E-Class or is training to be an assassin. He's hid it for most of his life, so imagine his surprise when a teacher notices something's off. Especially if that teacher was only there for the government and only knew them about a month. Yup, definitely surprising.
