Assassination Time

Mitsuki Kazuya was someone who was grateful for what he had and ignored what he didn't, even if that something was extremely important. For example, like most of his classmates in class-E gave up on their futures, he was just glad to get an education. Now new people are entering his tiny world, including a strange teacher who is he sees as basically an Octopus and who taunts him and his classmates to assassinate him.
