Assassination Classroom, Vol. 6

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?!
