Volume 7

On Island Time (島の時間) is the seventh volume of the Assassination Classroom manga.

Preface
''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?! ''

Author's Comment
''In Japan, Vol. 7 comes in two editions. There's the ordinary edition like the one you're currently holding and the Anime DVD Bundle Edition, which comes with a different cover illustration and some new pages. Since this series began, many people have been supporting it through various projects, collaborations and products. I can't thank them enough. Because of Korosensei's simple design, I start thinking, "Maybe I can ask them to do a collaboration with Korosensei!" whenever I see a round shape in town. But... I'll keep working diligently and reign in my greed.''
