This anime series was released last year in Japan and was picked up by Funimation for the US release. The first season has 22 episodes and the second season which will have 25 is currently coming out. A live-action movie is also out.
The series revolves around a reject class of high school students from class E that are tasked with trying to assassinate their new teacher. The teacher happens to be an alien octopus like creature who if not assassinated by graduation will destroy the world. The kids soon find out the task of killing Koro-sensei (as they cal him) is next to impossible because of his super human abilities.
Each student has their own troubles and backgrounds but the series seems to focus on one Nagisa who seems to be the weakest in the lot but has the most talent when it comes to blood lust. The cast can be a bit zany and the series takes on a very comical tone with bits of seriousness thrown in here and there.
I find this series very amusing and like that not everything is as it seems.
