Is the Sewer Cleaner a Bad Thing?

Every fight after that one is just sick, in my opinion. Cause someone needs to clean the sewers, you don't it? So i found it so funny when it was like, he goes lity and shambles. He's been caught up so many times. But then he remembers in his back story that he learned to use a certain attack,. If he uses resolve, he can be better. Ithought i found it. It tells chigo cona, like, i beg you to save rucia. And he certainly doesn't want a hundred her to get killed.
