No way he's dead just like that
Now I'm wondering if the person who sent him there is attempting an assassination.
As told, if he got in trouble, the brave territory is in trouble (this is only a possibility) so there is a possibility the Brave Territory will be used as a scapegoat. Now, why did this person send him there? The sword? How does this person know, and when he did, why is there a demon there in the literal exact place he was told to go,
This is just random bullshit, but this is clearly plotted
