The Butcher was not an easy opponent, not at all.
He was more powerful than other Bronze Knights and was a mid-grade Bronze Knight, but he had a big flaw when it came to fighting against Lyle, and that was his ability.
His ability was the same as Lyle's, albeit a weaker version. There had been cases of powerful humans having the ability to control blood, as well as other races having the same, but a vampire would always be superior when it came to that thanks to their race.
Not only was the power of blood manipulation something that a vampire would have boosted thanks to their race, but it would usually also be of a higher rank compared to the others.
