Megumi Yanagisa was everything a young girl should be: model student, aspiring performer, driven athlete, and... MEMBER OF THE END-CLASS?! As if maintaining her status as "Queen of Kunugigaoka" isn't enough, Megumi also has to juggle tutoring her defeated classmates and also working with the Ministry of Defense to assassinate an octopus-like, seemingly extraterrestrial being that happens to be the teacher of the End-Class! Will she be able to succeed in all of the duties given to her: assassinate Korosensei, pass finals, uncover the truth about her past, fight the voice inside her head, deal with confusing young love, and take down the A-Class?! We'll see!
To everyone my name is Aika Tora. To one, I'm Hime. I'm in class 3-E, also known as the End class of Kunugigaoka Junior High School. 70% of the moon was destroyed with a monster's power, permanently rending it into the shape of a crescent. The monster claims that within a year, Earth will also be destroyed by him but he teaches us in the mean time. The Japanese government promises a reward of ten billion yen, if we could kill the Mach twenty target before the year ends. Our goal, to kill our octopus teacher, that we named Koro-Sensei, and deal with everything else.
