Assassination Classroom, Vol. 9

6,What does a pathetic class of misfits have in their arsenal to combat their schoolteacher's alien technology, bizarre powers and...tentacles?! Ever caught yourself screaming, I could just kill that teacher? What would it take to justify such antisocial behavior and weeks of detention? Especially if he's the best teacher you've ever had? Giving you an F on a quiz? Mispronouncing your name during roll call...again? How about blowing up the moon and threatening to do the same to Mother Earth--unless you take him out first?! Plus a reward of a cool 100 million from the Ministry of Defense! Okay, now that you're committed... How are you going to pull this off? What does your pathetic class of misfits have in their arsenal to combat Teach's alien technology, bizarre powers and...tentacles?! Nagisa risks it all in an attempt to take down the mastermind behind the biological attack on his classmates. After the dust settles, Koro Sensei gives his all to ignite summer romance between his students. Turns out their English teacher Ms. Jelavitch has her sights on someone...and everyone wants to help her get her target--er, the man of her dreams. Then, back at school, one of the students defects from the 3-E ranks for all the wrong reasons. How will they win him back before he inflicts irrevocable damage on them all...?!
