"Cristopher, don't get too ahead of yourself," Thirteen said in a serious tone. "Don't bite off more than you can chew. Sure, higher-ranking Monsters are strong, but are you able to kill them?"
"… No, Young Master," Cristopher replied. "I'm sorry. I just became too ambitious."
"It's fine to be ambitious, but you must understand that a dead genius is no longer a genius," Thirteen stated. "You don't have to hurry. You will eventually acquire stronger Monsters as you progress through the Human Rankings. Now, let's continue."
Cristopher nodded and listened seriously to what his Young Master was about to say.
"The good thing about Brute Tamers is that the first Brute Monster Avatar that they obtain is special," Thirteen explained. "It will always have the ability to Evolve. This is why Brutus has the skill Evolver. In simple terms, as long as you spend time nurturing him, he will become one of your strongest supporters as you grow stronger."
