Once again, Hajime was not betrayed by his classmates. He was betrayed by ONE classmate, the others tried to save him. I keep seeing article after article acting like his entire class was out to get him...but that wasn't the case.

Maybe the manga is different, but I'm currently watching the Arifureta anime, and that description is not quite right. I'm halfway thru the second season, and it looks like his teacher and most of his classmates actually liked him. He was initially betrayed by only one classmate, who was jealous of him, because of a girl that liked him.

A couple of others end up betraying the group as a whole, not just him. But for the most part, his classmates seem decent.

Now the people who summoned him on the other hand..... But I still haven't seen evidence that they had anything against Hajime personally.
