I am a big fan of Assassination Classroom, so I made whatever this is.... Assassination Classroom is a Japanese graphic novel series by Yusei Matsui in which the moon is discovered to have 70% missing, and then an alien comes to earth claiming he was the one that destroyed the moon and he plans too do the same to the earth next march! In the meantime he says, he wants to teach class 3 E of Kunugigaoka junior high. No one knows why, but what they DO know is that the students of class E can help Assassinate this creature before he destroys the earth! But it won't be easy! This creature can move at Mach 20!! (Very fast!!!) Will the students of class E 3, home of dropouts and misfits, be able to kill this thing before he destroys the earth!?
The alien soon becomes known as, not "Weird Tentacle Thing", but Koro Sensei! (It's a play on words, Koro Senei means, "Can't Be Killed," and sensei means "Teacher"!) In order to kill him, they need special knives and BB's that aren't harmful to humans but lethal to Koro Sensei! The students are actually getting used to him!
