I’m going to call you parasite as from now on,”[You wouldn’t dare,]“ I just did and I would again, a thousand times,”[Why you little!!][Fine you win. What do I have to do to make you stop calling me that?]“Hmm, If you help me accomplish my mission of ending every single one of those who captured my mother.
