The answer to that question is: the child slave labor is opening Hell. I still want to know what's the deal with the Commanders metal form that makes them look like robots. If 5 balls have that much recoil, I wonder what the recoil for seven balls is on the KiRyoku Bazooka. Also they have no idea when Kou's birthday is so who knows how long he has before he becomes a Gouma. I wonder things are going better or worse for the Dairangers at times.
