The title is intriguing and basically made me watch this. It doesn't disappoint! It all starts with a explanation of why 2-E is full of would be assassins. Their teacher? A strange tentacled smiley face that is set to destroy the Earth in a year. The object of the class is to take out their teacher before that happens!
I found this to be amusing to watch as the class is legitimately being taught by this creature that states their goal is to kill him before time runs out. Who hasn't had a teacher they wished was in this position. Not to mention he can move at mach 20 and avoid bullets, missals, etc. The teacher has regenerative abilities to make the task more difficult and he enjoys the attacks against him. The weird setup pays off to set up an interesting show, that I can't wait to get more of. Definitely an anime ass anime that you need to watch!
