Volume 6

Swim Time (水泳の時間) is the sixth 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?!''

Publisher's Summary
The 3-E students discover that Koro Sensei's greatest weakness might be a common substance. Will they be able to use it to assassinate him while he helps Meg, formerly of the varsity swim team, with her greatest weakness? The next assassination attempt, implemented by Terasaka, is more elaborate but endangers his fellow students. Can he save them without saving his target? Then, the top class at school, including Principal Asano's son, conspires to prevent 3-E from ever rising closer to the top!

Author's Comment
''I often use current events and parody in my manga, but that's become a lot more difficult than it used to be. One major reason is the lack of subjects everyone has in common due to the decline in TV Viewership. Parodies aren't funny if you use subjects that only a handful of people can relate to. The diversity of culture is a fine thing, but every now and again, I would like to see the outbreak of a social phenomenon that every Tom, Dick and Harry knows about. For that to happen, I believe TV needs to make a comeback''
