When the girl kneels before him, he tells her that he's talking trash to her. He says that she's the lord of the fourth level, and he'll eat her trash and become the strongest gray in the world to leave the place for good. He's feeling weird, he says, because this is the crimson mountain city. He asks what the level is, and the girl says that it's like a twenty-five turning twenty-six. The girl tells him that they've killed two level three beasts, but he doesn't understand why they're not fighting a level four beast. He thinks that they killed a level two beast, and that's why the level difference is so big. He wants to know what the difference is between a level three beast and a level one. He looks at the conversion rate, which is the rate at which a person is transformed from one level to another. The conversion rate is the percentage of a person's original state to that of the transformed state. If a person has a conversion rate of 100%, he or she will become a "crimson." The transformation rate is so high that no one will want to go back to being a human.
