I'm surprised there are still people around even though the giant gate took weeks to open. It would be cool to get an explanation to how far the giants walked from the portal in order to justify that many civilians. And what happened to the rest of Japanese hunters?
The brat did acompany him to the battlefield after all, the author even tried to make him do something(lol), even though two armored shadows would be far more useful. Dude isn't even in armor, what was all that baggage for? I really hope the author isn't setting up some "emotional" death.
