This is a good anime about this octopus like guy that destroyed the moon. A bunch of kids get into the class called 3-E because of bad grades. The octopus guy comes into 3-E as their teacher. The bunch of students have to assassinate him before graduation otherwise he will destroy the world. And in episode 3 there comes the hot guy of the series. Going by the name Karma Akabane. The guy with red hair and gold and red-ish eyes. Too bad he's mine XD!
