Rizumu usually has a very energetic personality. She is very good at dancing. She seems to be knowledgeable about love from a certain book of hers. She gets riled up when anything involves food, especially when that food is meat. She is easily angered, and will yell whenever she does not like someone's attitude. She is easily smitten when she thinks of Hibiki, but is angry when Kanon keeps him to herself. This light personality is immediately erased when it comes to her mother and the Aurora Rising, which she so very much wants to jump. She will get completely serious and lose sight of her surroundings, and she becomes very passionate. For her goals, she will do most anything, even losing her heart.
