Also, for some reason, I see Suzume being more... childish is a word I'd use. Into things like wrestling. Playing detective. Just being more... juvenile. It could be a function the HiME festival stole most of her youth and innocence so to speak and she's making up for it. But it could also be how she handles her immortality: "I don't need to grow up so quickly".

Mind you this could cause her to be stuck as an immature brat.
