"I don't need comerades" yeah good fucking luck getting on that strong team with that attitude.
Seriously this series has potential but this wannabe "sasuke" type anti hero is annoying. He talks about wanting to get on a strong team but refuses a team exercise as if he expects to get on a team when he can't do teamwork.
Plus even if the teacher said killing him would be an "instant graduation" is he really dumb enough to think leaving his classmates to die and killing his teacher will go over well with the organization? No matter how their system works they aren't going to take kindly to someone who goes against everything that makes an organized group function.
