Continuity mistake: When the girl is tied up in the room, Haru shoots the big spear-like arrow through the room. When the machine that it's attached to comes through wall, it knocks the bomb off of the table it was sitting on. But, by the time the machine makes it through the other wall into the warehouse the bomb is neatly on the machine and removed from the room that the girl was in.
Continuity mistake: When Gobe parks the car by the counterfeiting warehouse near the ending, it's parallel with the warehouse's wall. When Haru gets out of the car, the front is pointed toward the wall. Then when Haru is climbing up the palm tree, you can see that the car is further away from the warehouse than it was before.
