I really wanted to give this a chance beacause of History Strongest Disciple Kenichi. But this MC is just too stupid.
Courage and friendship? He is not brave, he is just too stupid, as the MC seems to be completely unaware of the context, even after repeatedly being told how something is dangerous and that he could die he refuses to take anything seriously and keeps distracting everyone around him. And friendship? He is too unaware of the problems his "friends" have, just saving someone from dying/failing or being saved is not what many would call friendship. And then you may think that given that this is a school setting, he would use his new friends to improve and be a better agent right? Well, that goes to my final point...
The MC is weak and stupid and that's fine, but he shows barely any improvement and the only glimpse of any will to improve is shown as him cutting stuff with his sword, in a school made to teach on how to be a better agent, with many other students that are better than him and could help him improve in many areas, the ones that he keeps trying to be in good terms with (his "friends"), but he doesn't even try to talk to anyone about it, he just goes to cut stuff late on the day.
And if you don't like fanservice don't even try reading this manga.
