The monarchy of roses tonight.

Columbia is known because she came from a little Brazilian city to Hogwarts in second year, because she was expelled from there. She has the need to speak her mind, some teachers like her because of this and others hate. At least, that’s what she tells herself, she refuse to believe the reason is the house she is in. Columbia doesn’t express in words what she thinks about the others students; she doesn’t want to have to change schools. Again.
She somehow respect muggles, her little frog's name, Melchior, is inspired in a muggle musical. She is fine as a seeker, but she isn’t in the team; she is not good enough. Columbia devotes herself to classes because she is afraid of becoming some loser in the future. Not that she lets other people know this.
