Now that he's broken through the golden core, hades is ready to go home. He's got a new weapon, and he wants to show it off to kintaro. He wants to know if he can use it to destroy all the cities on Earth. He tells kintaro that the mang-gu-toad is dead, so he has extracted the soul of the creature and made it into a new vessel to use as a weapon. It's super-powers, kintaro says, and it's even better than an iron-clad beast because it can shrink and change its size at will. It can do this because its soul is weak in the back, like a weak spot in an ironclad body. So kintaro is super-excited to be back on his own again.
