Volume 9

A Shocking Time (衝撃の時間) is the ninth 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
''Whenever the popularity of a series is low, the story takes sharp turn or a new character who was never meant to appear is suddenly. We often refer to this as pandering. Luckily for me, I've never had to pander in my manga artist life so far. That is to say, thankfully I've never been in that position. But even if I do work on a series that isn't that popular, I probably wouldn't consider pandering to readers. People might think that means I'm not trying hard enough, but I want to build a trusting relationship with my readers as a manga artist who wraps up the story properly even if the series isn't super popular … that should cover any problems in the future (laughs)''
