Bam is already joke of a character in this first episode alone. That first episode was bad, the set-up and worldbuilding is generic and poorly defined, at one point they're just throwing out jargon terminology that Bam just repeats because he's an empty husk of a character.

Just being dropped in this empty hallway seemingly made only for Bam to do this thing, and then these two people come out of literally nowhere and just inject poorly disguised exposition making vague allusions to Bam's behaviour like it means anything to us.

They really try their best to make Bam just standing there like an idiot seem like some dramatic brilliant gesture and they needed the guy to just say "there is something special about this boy" even though all he does is trip over himself and show no ability to think on his own.

There's like an element where this one guy is like trying to give Bam some tips but the show also wants to manifacture tension so they cut him off, but then once he's in the middle of the challenge he can give us the full rundown, the entire reasoning for the scenario is thin.

Which includes him just being given a sword by Yuri who isn't even supposed to be there?? It's such a contrived "trial" that depends on what-ifs and weakly justified character decisions. Even the reason he can use the legendary sword when "even Yuri couldn't do it" is stupid.
