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?

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?! English teacher Irina's

everyone into a tentacle tizzy. Then the 3-E students face humiliation yet again during a
school baseball exhibition match. Plus more secrets of Koro Sensei's mysterious past
revealed...!
