Too Much Insanity {{Assassination Classroom Fanfiction}}

Prologue

We aren't normal kids.
Are parents are dead, we hacked into the government's computers and classified information, and we are pretty much assassins.
Who are we? Well, that's hard to say. Apparently, to the government, we're known as the Deadly Duo. In school we're know as the Invisible Two.
But who we really are, Akihiro and Mamoru Shimizu.
I'm Akihiro, believe it or not, even though my name is a boy's name, I'm a girl. The younger sister of Mamoru Shimizu.
I'm in 8th year junior high at Kunugigowka, and Moru is a freshman in highschool, sorta, he likes to lie about his age, so technically he's in 8th year too.
We might be invisible to all the other students, but not to the teachers or bullies. But, since we're different, I've actually broken a bully's arm. Why I did it?
Well, I guess it's because I don't like people beating each other for some stupid reason, so I broke the guy's arm.
Got detention but hey, that was a distraction. At that time Moru stole some stupid teacher's car.
Hot wired it, got me out of detention but got us in bigger trouble. We were heading to E-class. But I mean who cares? We get to kill a huge yellow octopus alien, not to mention, he's a teacher!
Yeah, that's right when we hacked the government, we found out about E-class, and we did every thing in our power, and not noticing we'd do these things, but we wanted in E-class.
Killing is our specialty, and our target is now our teacher.
