The last boss trophies have me curious as well:""End of the War" and "Hero of the Ninja World"
.......Isn't the war still going on at that point though? I'm not sure if one is the hero of the ninja world if a fight is clearly not over. Wouldn't they make a trophy title that relates to the final battle going further or something along the lines?
I'm sure they've come up with something, just look at Storm 2. Naruto beats Sasuke but they still fail to bring him back.
